Custom-Devboard: common questions

What microcontroller does the Custom-Devboard use?

The Custom-Devboard is built around the C2040, from the RP2040/RP2350 family.

How big is the Custom-Devboard PCB?

The Custom-Devboard measures 21 × 51 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Custom-Devboard?

39 components, from 22 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 Custom-Devboard design files?

From the dragonruler1000/Custom-Devboard 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 Custom-Devboard design in my own project?

Yes, under the terms of its CERN-OHL-P-2.0 license, which dragonruler1000 chose for the repository.

Can I test firmware for the Custom-Devboard 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.
