Raspberry Pi GPS HAT
This is a Raspberry GPS HAT expansion board designed specifically for the Raspberry Pi B+, A+ and Raspberry Pi 2 Model B! It's a simple to install and use GPS module, that utilises the Raspberry Pi the serial ports (UART) for communication. The board is compliant with Raspberry Pi HAT specification, and includes a 2x20 way header and stand-offs to provide a robust solution to Raspberry Pi GPS function.
We also have cases available for the Raspberry Pi and GPS HAT combination in Black and Clear, and you'll probably need an external Antenna to get going!
It's great for accurate timing applications or general applications that require GPS information. It's equipped with the latest Ublox MAX-M8Q low power, high performance positioning module and features an RTC Crystal for timing applications, making it more than adequate for a Pi based NTP Server. Its worth noting the module can, with a serial command, be placed in “Stationary” dynamic mode which is the default mode for the much more expensive timing modules.To facilitate PPS, the time pulse output is connected to GPIO18, so you can utilise this board to give NTP PPS discipline.
The board features an SMA Female connector for an active patch antenna power, PPS LED's, and an on board 6 hour supercap which can be used to retain any custom settings in the event of power loss.
Please Note. This board is NOT compatible with the original Raspberry Pi A and B boards.
Please Note. This board has firmware version 2.01 and is currently unable to receive Galileo signals.
