APM/Pixhawk, SR04 Ultrasonic Mounting plate with angle mounting points

**HC-SR04** Mounting plate for UAV (or other robotic stuff, like drones, copters, RC-Cars, ...). Please note, these SR04 ultrasonic modules are **not the regular SR04** - These special modules contain a second pcb with an Arduino to connect them onto a **PIXHAWK or APM 2.4.x** - the sensor is a **HC-SR04**.

The idea behind this part is, to mount your US sensors in different angles on your chassis. There is an center hole and a half circle hole with angle points (0, 22.5, 45.0, 67.5, 90.0deg)
