Midevil: common questions

What microcontroller does the Midevil use?

The Midevil is built around the Pico, from the RP2040/RP2350 family.

How big is the Midevil PCB?

The Midevil measures 464 × 118.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Midevil?

156 components, from 13 distinct parts. The full bill of materials is listed on this page.

Where can I download the Midevil design files?

From the dcpedit/midevil repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Midevil design in my own project?

Yes, under the terms of its CC-BY-4.0 license, which dcpedit chose for the repository.

Can I test firmware for the Midevil 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.
