SchematicProduct Overview
The SparkFun GNSS Flex pHAT is a Raspberry Pi pHAT that functions as a carrier board for our SparkPNT GNSS Flex modules. With pre-soldered headers, no soldering is required to stack the pHAT on the headers of a Raspberry Pi, NVIDIA Jetson Nano, Google Coral, or other single-board computer with a similar 40-pin header.
The GNSS Flex pHAT also comes with two sets of 2x10-pin, 2mm pitch male headers for attaching a GNSS Flex module. With these headers, the GNSS Flex system is designed to be modular, so boards are pin-compatible for upgrades and can be easily swapped out for repairs. Depending on the capabilities of the GNSS Flex module that is connected, these pins will breakout the USB, UART (x4), I2C, and SD card interfaces for the GNSS receiver, along with any PPS or event signals, using a standardized pinout.
By default, we use the Raspberry Pi's primary serial bus (i.e. TX: GPIO14/Pin 8; RX: GPIO15/Pin 9) to communicate with the GNSS receiver of the SparkPNT GNSS Flex module. However, users can also utilize any of the other interfaces.
