Useful Raspberry Pi HATs for ArduPilot

This repository contains 3x archived hardware PCB designs for Raspberry Pi HAT's, created in KiCAD.

The Kakute HAT is an expansion board for the Raspberry Pi, which allows a KakuteF4 (non-AIO) to be interfaced (send telemetry to the Pi). Additionally, it contains breakout ports for RC In, GPS, Servo Out and others.

It contains a 5V, 2.5A power supply for the Raspberry Pi and has power switches for both the Kakute and Pi.
