The BPH is a hat for the Raspberry Pi 3 designed to connect PHiLIP-b to a DUT (Device Under Test) which typically consists of a micro-controller development board.
It provides connections to communicate with PHiLIP, a convenient 20 pin ribbon cable for the pinout to the DUT and some power control and monitoring. The purpose is to make an easy to assembly and maintain setup for HiL (hardware in the loop) testing at a low cost.
The BPH was designed so a skilled hobbiest can reproduce it. The gerber files and BOM for the PCB should be enough to build a board. Board design files are also available. Manufacturing costs for 100 board units range between 1000 to 2000 EUR for a turnkey solution.
Along with the BPH board, a PHiLIP-b is needed.
A BPH interface is provided to make usage easier.
Using a standard ribbon cable to connect the BPH to the DUT the following wiring should be followed
