Ultrasonic Distance Sensor Breakout 4-tronix

This breakout is a simple and robust way to add ultrasonic distance sensing to your robot. Supported on Pi2Go Mk2, Pi-Bug (v1.1 and later), Minibit and other 4tronix robots. This breakout is fully compatible with Pimoroni"'s breakout garden, so you can plug it into any of the I2C connectors and use it on GPIO pin 4. It is a single pin, 3.3V sensor breakout. So the Ping and the Echo are on the same pin.
