Monitor 16 HC-SR04 Ultrasonic sensors at 5Hz, or 8 sensors at 10Hz. Collect distance data via RS232 or SPI bus to BBB.

Board has two RS232 ports, one connected to the PIC microcontroller and one connected to the BBB.

Supply 9-16 VDC, and board will regulate power to all circuitry including the BBB.

Note: This board can be used standalone without a BBB. Source code provided for BBB SPI bus interface to PIC microcontroller.
