From the project

A KiCad hardware project for a multi-channel DUT (Device Under Test) hub with integrated JTAG multiplexing, power management, and Raspberry Pi Pico control interface.

- 4-channel DUT interface with individual power control via TPS22992 - JTAG multiplexer for debug access to multiple targets - 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)

Dut hub hw: common questions

What microcontroller does the Dut hub hw use?

The Dut hub hw is built around the RaspberryPi_Pico, from the RP2040/RP2350 family.

How big is the Dut hub hw PCB?

The Dut hub hw measures 100 × 155 mm, has 4 copper layers and is 2.218 mm thick.

How many components are on the Dut hub hw?

147 components, from 29 distinct parts. The full bill of materials is listed on this page.

Where can I download the Dut hub hw design files?

From the Netlist-Studio/dut_hub_hw repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Dut hub hw design in my own project?

Yes, under the terms of its CERN-OHL-S-2.0 license, which Netlist-Studio chose for the repository.

Can I test firmware for the Dut hub hw without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
