Working with Raspberry Pi Pico

• If RTK functionality is needed, please use the Raspberry Pi Pico 2 W series and follow steps similar to those for the ESP32 to achieve RTK positioning. This section uses the Raspberry Pi Pico 2 as an example for basic GNSS positioning. The connection table is as follows:

  Raspberry Pi Pico 2	Q43 NEO-F9P GNSS Helical RTK Module
  GND	GND
  GP2	SDA
  GP3	SCL
  GP1	TX1
  GP0	RX1
  VBUS	VCC

• Open and run the GetGPS.py example in Thonny to obtain raw GNSS messages, as shown in the figure below:

  

• Run the QMC5883P.py example to measure the ambient magnetic field strength, as shown in the figure below:
