The Teseo-LIV3 GPS module (as used in shabaz ' GPS / Galileo / BeiDou / GLONASS receiver) talks UART and I2C. I developed an OO driver and parser for it.
The Raspberry Pico port of that library is now ready for release 2.0.
GitHub 2.0 release with binaries
Main changes:
- parser has more coverage for NMEA responses and attributes (everything used in shabaz' Arduino library)
- faster UART interface
- uses consistent naming conventions and C++ constructs, compliant with µOS coding standards.
- STL aggregate and filter examples
- Teseo and NMEA library now are STL container independent, and support embedded-friendly std::array

Pico resources used only if you use I2C:
- I2C0
- SDA: GP16 (Pico I2C0 SDA)
- SCL: GP17 (Pico I2C0 SCL)
- baud: 100 * 1000
for I2C, SDA connects to SDA and SCL to SCL. The PCB that I use has the pull-ups for I2C.
Pico resources used only if you use UART:
- UART1
- TX: GP4 (Pico UART1 RX)
- RX: GP5 (Pico UART1 Tx)
- baud: 9600
- UART1 RX interrupt
for UART, RX connects to TX and vice versa
Pico common resources:
- RESET: GP18 (optional)
- 5V: VBUS
- 0V: GND
