Launch and track model rockets via smartphone #Feather

Hackaday writes about a project which mounts an Adafruit M0 Feather microcontroller board into a rocket, along with a 900 MHz LoRa transmitter and a GPS module. This allows the rocket’s journey to be measured and logged, and is particularly useful for when a craft floats off downrange during parachute recovery. There’s also a relay module onboard, which dumps power from a dedicated separate battery into the rocket motor igniter. This allows the rocket to be fired wirelessly.

On the ground, the setup uses an ESP32 fitted with another LoRa module to receive signals from the rocket. It’s designed to hook up to an Android smartphone over its USB-C port. This allows data received from the rocket to be displayed in an Android app, including the rocket’s GPS location overlaid on Google Maps.
