ATX PSU ProtoHAT for Raspberry Pi

ATX-PSU-ProtoHAT project test HAT board for ATX PSU.

ATX-PSU-ProtoHAT is a prototyping HAT board for DIY use. This board features Raspberry Pi and ATX PSU connector.

- Raspberry Pi 40-pin connector - ATX PSU 24-pin connector - DIY raster DOT area for prototyping

- Fixed board geomery to fit better to Rasperry Pi HAT spec - Added few more DIY raster lines - Fixed typo in pad's description - Moved texts around

ATX-PSU-ProtoHAT: common questions

What microcontroller does the ATX-PSU-ProtoHAT use?

The ATX-PSU-ProtoHAT is built around the PI_CONN, from the Raspberry Pi family.

How big is the ATX-PSU-ProtoHAT PCB?

The ATX-PSU-ProtoHAT measures 65 × 56.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ATX-PSU-ProtoHAT?

19 components, from 14 distinct parts. The full bill of materials is listed on this page.

Where can I download the ATX-PSU-ProtoHAT design files?

From the red-scorp/ATX-PSU-ProtoHAT repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the ATX-PSU-ProtoHAT design in my own project?

The repository has no license, so all rights stay with red-scorp. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the ATX-PSU-ProtoHAT without the hardware?

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