Over the last few days I took the bold step of putting my entire autopilot concept on a single board. Leaving the convenient use of Arduino shields behind and heading towards developing a full blown flight controller comprising of:
- 3.3V additional regulator for sensor power supply.
- 6DOF IMU - accelerometer and gyroscope
- Magnetometer board
- Logging capabilities (with OpenLog board)
- 4 servo inputs (can be extended to 5 in the future)
- Female headers for quick sketch modification and upload
- LED light for testing purposes
- Provision for a barometric altimeter and GPS sensor
- Total board weight: 30g (as compared to the previous board or 90g)
I've tested the logging of IMU and servo inputs and the board is ready for it's first Test bench logging test. I would have taken this straight up in the air but having learned that everything is in moderation, I realised that 'baby' steps is your ONLY friend.
