Does a USB drive get heavier as you store more files on it?

Nope. Paradoxically (and theoretically), the more you save on a flash drive, the lighter it gets.

USB drives use Flash memory, which means the the ones and zeros of the data are stored on transistors.

When you save data, a binary zero is set by charging the float gate of the transistor, and a binary one is set by removing the charge.

To charge it, we add electrons, and the mass of each electron is 0.00000000000000000000000000091 grams.

This means that an empty USB drive (which mostly holds zeros) weighs more than a full USB drive (which has ones and zeros). Add data, reduce the weight.

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.
