I built (and currently testing) a 4 port automated PCB test & programming tool. I needed a way to produce a bunch of PCBs efficiently and couldn't find a solution that was flexible and didn't cost many thousands of dollars. I made a simple tool to solve this.

Features

    - 4-channel DUT interface with individual power control via TPS22992
    - JTAG multiplexer for programming (not exclusive to JTAG)
    - Power monitoring using PAC1954 for per-channel current/voltage measurement
    - Raspberry Pi Pico for control logic and automation
    - USB interface through Pi Pico USB-CDC for host communication (1 port for each DUT)
    - 1.8V - 5V IO support
    - MicroPython support for test script automation
