25pix: common questions

What microcontroller does the 25pix use?

The 25pix is built around the C132230, from the AVR/Arduino family.

How big is the 25pix PCB?

The 25pix measures 60 × 96 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the 25pix?

60 components, from 17 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the 25pix design files?

From the bnaucler/25pix repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the 25pix design in my own project?

Yes, under the terms of its MIT license, which bnaucler chose for the repository.

Can I test firmware for the 25pix without the hardware?

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