Octasonic HC-SR04 Breakout

The Octasonic HC-SR04 Breakout provides a simple way to connect up to 8 HC-SR04 ultrasonic sensors to a Raspberry Pi, Arduino or any other single board computer or microcontroller that uses either 5V or 3.3V and supports SPI.

The Octasonic breakout can be purchased from my Tindie store.
