Building an open source flight logger

By Scooter Y and Liam G


About:

The Goal of this project was to build a simpler datalogger for model rockets to collect the info needed for most rocketiers from multiple sensors including an IMU and Baro. We built this as a dev board so when we eventually produce the larger V1 board, we can weed out issues before spending $400.

Features:

  • This whole board is under $50 USD.
  • One ARMCortex M0+ MCU
  • IMU and Barometer
  • SD and NAND Datalogging
Checkout locally
