On  Wednesday 28th January 1829, the notorious William Burke was hanged in Edinburgh.

He and his accomplice William Hare, who escaped the death penalty by turning King’s ­Evidence against Burke, were caught murdering people in the city and selling the cadavers to ­anatomist Robert Knox.

The hanging took place in Edinburgh at Libberton’s Wynd, this street ran from High Street/Lawnmarket down to Cowgate, roughly where the East pavement of George IV Bridge is now.

Below is the story The Scotsman ran about the execution

Pursuant to sentence passed in the High Court of Justiciary, Burke this morning suffered the last sentence of the law, at the common place of execution, head of Libberton’s Wynd.

From the hour in which he heard that his associate Hare was to be admitted an evidence against him, he abandoned all hopes of acquittal, and resigned himself to his awful fate. When consigned to the silence and solitude of his cell, he eagerly availed himself of the consolations of religion and sedulously ­prepared for the awful change he was soon to undergo. Sincerely anxious to hear of the premises of pardon and acceptance which the gospel holds out to the contrite and repentant sinner, on one occasion when a Catholic Priest and the Rev. Mr Marshall arrived at once at the jail, he exclaimed “admit them both”.

In a short time, however, he ­dispensed with the visits of Mr ­Marshall, and resolved to die ­professing the faith of his ­forefathers. Thought he talked ­freely over his murders at all time, he spent much of his time in reading such books as were left by his ­spiritual instructors, and in deep and serious meditation.

Heavily manacled as he was, and confined to the murderer’s diet – bread and water – he uniformly manifested an astonishing ­calmness and contentment. One gentleman, by whom he was visited, remarked that his cell was very cold, “Yes, yes,” he promptly replied, “but since matters have come to this, I must just bear it all.”

Though dreadfully afflicted by an excruciating disease and tormented by the approach of an ignominious death, he acted with deliberation; and talked with perfect coherence.

Shortly after eight o’clock, the procession set out for the place of execution. Bailies Crichton and Small, with a party of town officers, first ascended the scaffold and they were followed by Burke, supported by two Catholic Clergymen. He was dressed in decent black clothes, and was perfectly firm and ­composed. The moment he appeared the crowd set up an appalling shout, which continued for several ­minutes. The murderer and the Catholic clergymen knelt down and spent a few minutes in ­devotion. During the time a deep silence ­prevailed among the assemblage, but the devotions were ­succeeded by vehement cheering from every quarter, mingled with groans and hisses. When the cheers had subsided, the wretched man was assailed with every epithet of contempt and abhorrence.

As soon as the executioner ­proceeded to do his duty, the cries of “Burke him, Burke him, give him no rope,” and many others of a similar complexion, were vociferated in voices loud with indignation. Burke in the meantime, stood ­perfectly unmoved, and gazed around till the cap was drawn over his face, and shut the world forever from his view.

The executioner having completed his preparations and placed the signal in Burke’s hand, the magistrates ministers, and attendants left the scaffold. The crowd again set up another long and loud cheer, which was followed by cries for “Hare, Hare, where is Hare.” Burke lifted his hands and ejaculated a prayer of a few sentences then dropped the napkin and momently the drop fell.

The struggle was neither long nor apparently severe, but at every ­convulsive motion, a loud huzza arose from the multitude, which was several times repeated after the last agonies of humanity were past.

What are the advantages and features of a wireless serial module? How is a wireless serial module used?

SV651 is an Industrial class & highly-integrated RF module. TTL / 232 /485 can be chosen corresponding to SV651-TTL / SV651-232 / SV651-485. SV651 has good sensitivity and 500mW output power to achieve long RF range and reliable RF communication. To avoid the interference, SV651 provides 40 frequency channels and configurable Net ID. SV651 is flexible but easy to use , it comes with many parameters, such as: frequency, data rate, output power, Net ID, Node ID. Users can configure the parameters through PC or customer’s own device.

Wireless serial is a wireless communication technology that allows devices, which would typically connect via wired connections (such as RS232, RS485, and other standard serial interfaces), to transmit data wirelessly. A wireless serial module usually consists of two parts: a transmitter and a receiver. The transmitter converts serial data into wireless signals and transmits them, while the receiver receives the wireless signals and converts them back into serial data.

Advantages of Wireless Serial Modules

Easy installation: No need to lay physical cables, reducing wiring costs and complexity. Flexibility: Facilitates communication between mobile devices and makes it easy to expand and reconfigure network layouts. Transmission range: Compared to wired communication, wireless serial can transmit data over distances ranging from tens of meters to several

kilometers. Some specially designed modules can achieve even longer transmission distances.

High output power: An output power of 500mW ensures stable communication over a large range, allowing the signal to be transmitted over greater distances with reduced susceptibility to interference.

Ultra-low sensitivity: A sensitivity of -121 dBm enables the detection and reception of extremely weak signals, ensuring the device can operate normally even in noisy environments by extracting useful signals.

Data Rate: In an open, unobstructed environment, the maximum transmission distance of the SV651 wireless serial module can reach 2800 meters at a data rate of 1.2Kbps. You can select an appropriate communication rate based on data transmission needs to ensure real-time and accurate data transfer.

Operating Frequency Bands: Options include 433/470/868/915 MHz. Select the appropriate frequency band according to regional regulations to avoid interference with other wireless communication devices.

Industrial-grade Interference Resistance: The wireless serial module can operate stably and reliably in noisy, interference-prone industrial environments.

Efficient Watchdog Design: In the event of an anomaly, the module will automatically restart and continue working according to the previous parameter settings.

Built-in Hardware Anti-crash Auto-reset Circuit: This circuit effectively prevents the device from freezing or malfunctioning. It can automatically detect issues and trigger a reset operation, allowing the device to restart and resume normal operation.

RSSI Signal Strength Detection Function: When the module switches to configuration mode, the RF will detect the surrounding signal strength in real-time. Users can send corresponding commands through the serial port to obtain the current real-time signal strength value of the module.

Wide Range of Applications: Widely used in industrial automation, remote monitoring, smart homes, wireless meter reading, access control systems, and various wireless data collection scenarios.

Wireless Serial Module Usage Method

Hardware Connection: Connect the wireless serial module to the serial port of the target device using a serial cable (such as RS232, RS485, TTL, etc.)

According to the module's requirements, provide the module with the appropriate power supply

Parameter Configuration

In working mode, pull low the SET pin to force SV651 into setting mode. When using USB bridge board, simply put on the short cap to enter into setting mode.

In setting mode, both blue and red LED will light on, shown as below:

Diverse Serial Port Parameter Settings

Once the module is successfully connected, it enters the "parameter setting" state. Users can modify the module's relevant parameters through a PC interface.

Data Transmission

Once configured, the wireless serial port module can convert serial port data into wireless signals and transmit the data to the target receiving device. The receiving device receives data through the wireless serial port module and converts it back into serial port data output to the target device.
