Devpad: common questions

What microcontroller does the Devpad use?

The Devpad is built around the XIAO-RP2040-DIP, from the RP2040/RP2350 family.

How big is the Devpad PCB?

The Devpad measures 99 × 99 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Devpad?

34 components, from 3 distinct parts. The full bill of materials is listed on this page.

Where can I download the Devpad design files?

From the Devansh-Singh-Parmar/devpad repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Devpad design in my own project?

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

Can I test firmware for the Devpad 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.
