USB RTC for Raspberry Pi: The Best Way to Enhance Your Raspberry Pi's Time Accuracy

When it comes to building real-time applications with the Raspberry Pi, one of the most crucial components to ensure is timekeeping. A RTC (Real Time Clock) module provides the Raspberry Pi with a reliable source of time, even when the system is powered off. For those looking to achieve incredibly accurate timekeeping, a USB RTC for Raspberry Pi is a solution that combines the DS3231 RTC chip with a MCP2221 USB to I2C/UART converter is a perfect match.

In this blog post, we'll dive deep into what makes this USB RTC setup an ideal choice for your Raspberry Pi projects, and how it enhances accuracy, reliability, and ease of use.

What is USB RTC?

RTC is a device which is used for maintaining accurate time in the host’s system processor. With the Raspberry Pi, the internal clock relies on the system supply to track the accurate time and the main issue is when the Raspberry Pi is powered off, the clock resets. USB RTC is a solution for providing accurate timekeeping even when the Raspberry Pi is turned off or disconnected from the network. This setup allows users to easily add accurate timekeeping to their Raspberry Pi without using the GPIO pins.

The USB RTC is a device which comes with a strongly integrated DS3231 circuit that is used to consume less power and has an integrated temperature-compensated crystal oscillator. It has MCP2221, a USB-to-UART/I2C serial converter that provides USB connectivity, used in Raspberry Pi operations that contain USB, UART(Serial), GPIO, and I2C interfaces. This module can be used with Raspberry Pi, Windows, Linux or any other operating system.

Key Features & Specifications:

DS3231 RTC Circuit: The DS3231 provides a highly stable timekeeping function and includes a built-in temperature-compensated crystal oscillator (TCXO), which helps maintain accuracy across a wide temperature range.

Temperature-Compensated Crystal Oscillator (TCXO): This is a critical feature of the DS3231. TCXO compensates for temperature variations that could affect timekeeping accuracy. This ensures the RTC module performs well in a range of environments without the need for external temperature sensors.

Battery Backup (CR1220, 3V): The module uses a CR1220 coin-cell battery to maintain time even when the Raspberry Pi is powered off. This ensures your system's time is preserved even in the event of power failure or system reboot.

16-pin, 300-mil SO Package: The module comes in a compact and durable 16-pin, 300-mil SO (Small Outline) package. This size makes it easy to integrate into your projects.

Automated Backup Power Supply: The onboard battery backup power supply ensures your RTC chip continues to run and track time even when the Raspberry Pi is turned off or disconnected from power.

Fast 400kHz I2C Interface: The RTC communicates with the Raspberry Pi using a 400kHz I2C interface, allowing fast and efficient data transfer. This is crucial for time-sensitive applications, as it minimizes any lag or delay when reading the time or setting the RTC.

MCP2221 USB to I2C/UART Converter: The MCP2221 is a USB-to-I2C and UART converter that makes it easy to connect the RTC to the Raspberry Pi via a USB port. This eliminates the need for GPIO pins, making it a plug-and-play solution for Raspberry Pi users.

USB 2.0 Compatibility: The module uses USB 2.0 for a fast and stable connection to the Raspberry Pi, offering plug-and-play functionality without requiring complicated wiring or software configuration.

Plug-and-play: The device is plug-and-play, with available drivers for various operating systems, including Linux, ensuring smooth integration with the Raspberry Pi.

High Accuracy: ±2ppm from 0°C to +40°C: Offers incredible timekeeping accuracy of ±2ppm (parts per million) between 0°C and +40°C. This means that, in a typical environment, the RTC will deviate by no more than 2 seconds per day—a level of precision ideal for most hobbyist and professional projects.

Extended Accuracy Range: ±3.5ppm from -40°C to +85°C: In more extreme conditions, such as outdoor or industrial applications, this module maintains an accuracy of ±3.5ppm in the temperature range of -40°C to +85°C. Whether you're working in a chilly warehouse or a hot outdoor environment, this module ensures your Raspberry Pi’s timekeeping remains precise.

Versatile Timekeeping: The module doesn’t just count seconds and minutes; it also tracks days, dates, months, and even the year with leap year compensation valid until the year 2100. This makes it perfect for long-term projects, as you can rely on the RTC to keep accurate time for many years to come.

Two Time-of-Day Alarms: With two independently programmable time-of-day alarms, this RTC module allows you to set scheduled events. Whether you need to trigger an action, send a notification, or turn on/off a device at specific times, the alarms make it easy to synchronize with your Raspberry Pi’s actions.

Programmable Square-Wave Output: The square-wave output feature allows you to generate periodic signals that can be used to sync other devices. Especially useful in projects that require precise timing for communications or measurements.

Use Cases:

Data logging: For applications like weather stations or scientific experiments, you need precise timestamps for each data point.

Embedded systems: For embedded systems that require time-based tasks (like alarms or scheduled events), the RTC ensures that the system runs on a stable, reliable time.

Low-power applications: The RTC ensures your Raspberry Pi can operate in low-power or battery-operated setups while maintaining the correct time.

IoT devices: When building IoT applications where devices may not always have a constant internet connection, having a local, accurate time source is essential.

Conclusion: 

For projects that demand extremely accurate timekeeping, the combination of the DS3231 RTC chip and the MCP2221 USB to I2C/UART converter is an excellent solution. This setup not only provides highly accurate, temperature-compensated time tracking but also integrates seamlessly with the Raspberry Pi via a fast I2C interface. 

Whether you're building a weather station, data logger, or any time-sensitive project, the DS3231 with MCP2221 ensures that your Raspberry Pi has reliable, battery-backed, and accurate timekeeping capabilities that won't be affected by power outages or system restarts.

A Compact Pi Compute Module Backpack 🍓🥧📸🎒

We used to stock a PiCam Module

that would plug into a Pi CM4 or CM5 - recently we went to restock it, but the vendor hasn't replied to our emails for many months. So, it could be a good time for us to design something that works similarly but with more capabilities. So we tasked Timon

with designing something for us - we just said, "Make the best thing ya can," and he delivered! Check this board out that plugs onto the compute module and provides many great accessories: USB connection for bootloading/USB gadget, USB 3.0 host type A for CM5, micro HDMI, micro SD card for data storage on 'Lite modules, camera connection, and mount, two DSI connectors, fan connect, Stemma QT / Qwiic connection, and RTC battery. There's one shutdown button for CM5 and two GPIO buttons plus one LED. Timon's gonna try to add an EYESPI connector for our next rendering so we can get some I2C/SPI/PWM outputs easily. What do you think? We wanted to keep it compact and not too pricey (aiming for <$30 cost. We'll see if we can get it there) but were able to craft fairly complex projects in a small space.

Arduino und DS3231: Relais jeden Tag automatisch zu variablen Uhrzeiten schalten

Im Beitrag Arduino und DS3231: Relais jeden Tag automatisch zur gleichen Uhrzeit schalten habe ich dir gezeigt, wie du ein Relais zu einem fest definierten Zeitpunkt aktivierst. Aufbauend auf diesem Wissen erkläre ich dir heute, wie du das System erweiterst, um an mehreren Zeitpunkten pro Tag automatische Schaltvorgänge durchzuführen. https://youtu.be/rZtfyYJyA_0 Hinweis: Die Idee zu dieser Erweiterung entstand aus einem Wunsch eines Lesers meines Blogs, der sich eine Mehrfachschaltung des Relais gewünscht hat. Wenn auch du Anregungen, Fragen oder Wünsche hast, melde dich gerne per E-Mail oder schreibe mir in den Kommentaren.

Rückblick - Aufbau der Schaltung und benötigte Ressourcen

Für den Aufbau der Schaltung benötigt man: - einen Arduino Nano V3* - ein USB-Datenkabel* - eine RTC DS3231* - ein 2fach Relais-Modul* - ein 20x2 LC-Display mit I2C Schnittstelle* - diverse Breadboardkabel* - ein 400 Pin Breadboard*

zeitgesteuerte Schaltung mit dem Arduino UNO R3, RTC und LCD-Display Für die Schaltung verwende ich den Maker Nano welchen ich dir im Beitrag Vorstellung des Maker Nano von Cytron vorgestellt habe. Dieser hat die Abmaße des Arduino Nano bietet aber ein paar nette zusätzliche Features.

Erweitern des bestehenden Codes

Wie bereits erwähnt, habe ich das kleine Projekt bereits vorgestellt. Nun gehe ich auf die notwendige kleine Änderung ein, die es ermöglicht, pro Tag mehrere Schaltvorgänge umzusetzen. Schritt 1 - Strukturen zum ablegen der Zeiten anpassen Da das Projekt nun darauf abzielt, das Relais täglich zu festen Uhrzeiten zu steuern, ist es nicht mehr notwendig, auch das Datum zu berücksichtigen. Ursprünglich war die Struktur so aufgebaut, dass sie an einem bestimmten Datum und zu einer bestimmten Uhrzeit aktivierte – das Datum war also ein entscheidendes Kriterium. Jetzt, wo die Schaltvorgänge jeden Tag erfolgen, genügt es, nur die Uhrzeit zu prüfen. Das Datumsfeld kann daher entfernt werden, was den Code übersichtlicher und zielgerichteter macht. // Struktur für einen RTC-Zeitstempel. // Speichert Datum und Zeit als Strings, wie sie z.B. von einer Real-Time Clock (RTC) geliefert werden. struct RTC_Zeitstempel { String datum; // Datum als String, z.B. "2025-02-23" String zeit; // Zeit als String, z.B. "12:34:56" }; // Struktur für einen allgemeinen Zeitstempel. // Enthält zwei Zeitangaben: eine für das Einschalten (ON) und eine für das Ausschalten (OFF) des Relais. struct Zeitstempel { String zeitON; // Zeitpunkt, zu dem das Relais eingeschaltet werden soll String zeitOFF; // Zeitpunkt, zu dem das Relais ausgeschaltet werden soll }; // Struktur zur Darstellung eines Relais. // Speichert Informationen über das Relais und die zugehörigen Schaltzeitpunkte. struct Relais { int digitalPin; // Digitaler Pin, an den das Relais angeschlossen ist String desc; // Beschreibung oder Name des Relais int numZeitstempel; // Anzahl der aktuell gesetzten Zeitstempel im Array Zeitstempel zeitstempel; // Array, das bis zu 10 Zeitstempel (Schaltvorgänge) aufnehmen kann }; Schritt 2 - Anpassen der Funktion zum auslesen der aktuellen Uhrzeit von der RTC DS3231 Die Struktur zum speichern des aktuellen Zeitstempels habe ich umbenannt, daher musste im Code dieses an den entsprechenden Stellen angepasst werden. void loop() { ... //bleibt leer RTC_Zeitstempel zeitstempel = readRtc(); … } //auslesen der Daten von der RealtimeClock RTC_Zeitstempel readRtc() { ... } void checkCurrentTimestamp(Relais relais, RTC_Zeitstempel zeitstempel) { ... } Schritt 3 - prüfen aller gespeicherten Zeiten Die Funktion checkCurrentTimestamp dient dazu den aktuellen Zeitstempel gegen die gespeicherten Zeiten für die beiden Relais zu prüfen. // Funktion zum Überprüfen, ob der aktuelle RTC-Zeitstempel einem // der definierten Schaltzeitpunkte des Relais entspricht. void checkCurrentTimestamp(Relais relais, RTC_Zeitstempel zeitstempel) { // Schleife über alle gesetzten Zeitstempel für dieses Relais for (int index = 0; index // Aktuellen Zeitstempel (mit On- und Off-Zeit) aus dem Array lesen Zeitstempel relaisZeitstempel = relais.zeitstempel; // Überprüfen, ob die aktuelle Zeit mit der Einschaltzeit übereinstimmt if (zeitstempel.zeit == relaisZeitstempel.zeitON) { // Ausgabe an den seriellen Monitor, dass das Relais aktiviert wird Serial.println("aktivieren"); // Relais aktivieren digitalWrite(relais.digitalPin, LOW); // Überprüfen, ob die aktuelle Zeit mit der Ausschaltzeit übereinstimmt } else if (zeitstempel.zeit == relaisZeitstempel.zeitOFF) { // Ausgabe an den seriellen Monitor, dass das Relais deaktiviert wird Serial.println("deaktivieren"); // Relais deaktivieren digitalWrite(relais.digitalPin, HIGH); } } } fertiges Projekt Hier kannst du das fertige Programm als ZIP-Datei herunterladen.

Ausblick - Relais zu variablen Uhrzeiten schalten

Nachdem in diesem Projektkommentar auf Wunsch eines Lesers bereits die Funktionalität um mehrere Schaltzeitpunkte erweitert wurde, steht nun der nächste Schritt an: der Umstieg auf den ESP32. Mit dem integrierten WiFi bietet der ESP32 enorme Vorteile, denn zukünftig sollen die Schaltzeiten flexibel und benutzerfreundlich über eine eigene Webseite konfigurierbar sein. Außerdem wird die aktuelle Uhrzeit nicht mehr ausschließlich von einer RTC ermittelt, sondern direkt von einem NTP-Zeitserver aus dem Internet bezogen – für eine präzise und wartungsfreie Zeitsynchronisation. Diese Neuerungen machen das Relaissteuerungs-Projekt noch flexibler und vielseitiger.
