Dev expansion card: common questions

What microcontroller does the Dev expansion card use?

The Dev expansion card is built around the RP2040, from the RP2040/RP2350 family.

How many components are on the Dev expansion card?

35 components, from 16 distinct parts. The full bill of materials is listed on this page.

Where can I download the Dev expansion card design files?

From the boredom101/dev-expansion-card repository on GitHub, which has a netlist; the links under Design files point to each one.

Can I use the Dev expansion card design in my own project?

Yes, under the terms of its MIT license, which boredom101 chose for the repository.

Can I test firmware for the Dev expansion card 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.
