This repository contains the design files and software for the Blue pill based High Altitude Balloon tracker.
The main components of the system are:
- STM32F103 based Blue pill arduino board
- Ublox MAX-M8Q GPS on breakout board
- NTX2B-FA Radio module
- MPU-9250 9DOF Module 9 Axis Gyroscope Accelerometer Magnetic Field Sensor on breakout board
- SD card reader on breakout board
- potentially other sensors as well
The microcontroller is programmed with an ST Link and the serial debug info is transmitted via the in built USB connection on the Blue pill
