## AI overview

A review of Uputronics' GPS/RTC Raspberry Pi Expansion Board, tested with the galmon.eu GNSS monitoring project. The board uses a u-blox M8 timing receiver, provides raw GNSS and correlator data, and offers a stable clock signal. The review also covers antenna performance, Raspberry Pi 4 configuration, UART communication, and baud-rate considerations.

## Source excerpt

Hi everyone, Disclaimer: this is a review of a free sample I got sent by Uputronics. I recently spotted on Twitter that Uputronics had launched a GPS/RTS Raspberry Pi Expansion Board, and that they were looking for worthy projects to test it. I thought our Galileo/GPS/BeiDou/GLONASS monitoring project galmon.eu might be worthy and Uputronics agreed. Relevant for our purposes, this is an actual 'timing receiver'. Any GNSS chip will get you a location, but some of them go the extra mile to also deliver a very stable clock signal.
