Pico weather balloon datalogger project. Powered by the Raspberry Pi Pico.
todo
This project is designed to work with the following components (links are examples):
- Raspberry Pi Pico (can be downclocked)
- RFM9x LoRa radio chip
- MCP9808 Temperature Sensor
- BMP3XX Temperature and Humidity Sensor
- Fat32 SD Card + Reader
- GPS/NMEA GPS chip (using UART)
- RGB LED (common cathode)
You will need the following libraries (all are in the Arduino library manager as well):
- Arduino-Pico (board manager)
- Adafruit BMP3XX
- Adafruit MCP9808
- Arduino-LoRa
- TinyGPSPlus
The hardware used is fully customizable using these headers.
The pinouts can be found here and can be customized using these headers. Make sure that they use the corresponding interface and are valid pins for that interface, otherwise the Pico will just hang.
