The KiCad project lives in the PinguinoIDE/pinguino-cad repository on GitHub; these links point at the commit this page was built from.

32mx2xx: common questions

What microcontroller does the 32mx2xx use?

The 32mx2xx is built around the PIC32MX250F128B, from the PIC family.

How big is the 32mx2xx PCB?

The 32mx2xx measures 64.1 × 33.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the 32mx2xx?

38 components, from 21 distinct parts. The full bill of materials is listed on this page.

Where can I download the 32mx2xx design files?

From the PinguinoIDE/pinguino-cad repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the 32mx2xx design in my own project?

Yes, under the terms of its GPL-2.0 license, which PinguinoIDE chose for the repository.

Can I test firmware for the 32mx2xx without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug PIC firmware against it before you order a PCB.
