Astrapad: common questions

What microcontroller does the Astrapad use?

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

How big is the Astrapad PCB?

The Astrapad measures 99.9 × 54.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Astrapad?

34 components, from 7 distinct parts. The full bill of materials is listed on this page.

Where can I download the Astrapad design files?

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

Can I use the Astrapad design in my own project?

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

Can I test firmware for the Astrapad 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.
