Pigmy-CoryDora: common questions

What microcontroller does the Pigmy-CoryDora use?

The Pigmy-CoryDora is built around the RP2040-Zero, from the RP2040/RP2350 family.

How big is the Pigmy-CoryDora PCB?

The Pigmy-CoryDora measures 82.8 × 25.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pigmy-CoryDora?

9 components, from 5 distinct parts. The full bill of materials is listed on this page.

Where can I download the Pigmy-CoryDora design files?

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

Can I use the Pigmy-CoryDora design in my own project?

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

Can I test firmware for the Pigmy-CoryDora 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.
