Ephys test board: common questions

What microcontroller does the Ephys test board use?

The Ephys test board is built around the SC0914(13), from the RP2040/RP2350 family.

How big is the Ephys test board?

The Ephys test board measures 150 × 120 mm, has 4 copper layers and is 1.5842 mm thick.

How many components are on the Ephys test board?

542 components, from 56 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Ephys test board design files?

From the open-ephys/ephys-test-board repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Ephys test board design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Ephys test board 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.
