Baker link dev hardware: common questions

What microcontroller does the Baker link dev hardware use?

The Baker link dev hardware is built around the Raspberry_Pi_RP2040, from the RP2040/RP2350 family.

How big is the Baker link dev hardware PCB?

The Baker link dev hardware measures 21 × 51 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Baker link dev hardware?

71 components, from 28 distinct parts. The full bill of materials is listed on this page.

Where can I download the Baker link dev hardware design files?

From the Baker-link-Lab/baker-link-dev-hardware repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Baker link dev hardware design in my own project?

Yes, under the terms of its CERN-OHL-P-2.0 license, which Baker-link-Lab chose for the repository.

Can I test firmware for the Baker link dev hardware 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.
