Dev: common questions

What microcontroller does the Dev use?

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

How big is the Dev PCB?

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

How many components are on the Dev?

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

Where can I download the Dev design files?

From the pranavrasam001-tech/dev repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Dev design in my own project?

The repository has no license, so all rights stay with pranavrasam001-tech. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Dev 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.
