Working with Raspberry Pi Pico

• If RTK functionality is needed, please use the Raspberry Pi Pico 2 W series and refer to steps similar to ESP32 to achieve RTK positioning. Here, the Raspberry Pi Pico 2 is used as an example to test standard GNSS positioning (GNSS positioning is also the most basic function of the LG290P GNSS RTK Module). The wiring diagram is as follows:

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

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

  

• Run the IST8310.py example to measure the spatial magnetic field intensity, as shown in the figure below:
