I’ve released a HAT for the Raspberry Pi for simplifying integration into a UAV. It’s essentially a 5.1V/3.5A power supply, JST-GH telemetry connector to flight controller and an on/off switch for safety powering down the RPi (reducing the risk of file system corruption).
This was inspired by a flight where the serial cable between the RPi and flight controller came loose inflight, leading to a loss of geotagging for the image capture software running on the RPi.
It’s designed for reliability and the power supply has the following features:
- Wide input voltage (7 – 30V)
- Reverse input protection
- ESD protected
- Supplies a full 5.1V at 3.5A for the Pi and accessories
- Overcurrent protection
- Short circuit protection
