Pixl.js: common questions

What microcontroller does the Pixl.js use?

The Pixl.js is built around the nRF52832-QFxx, from the Nordic nRF family.

How big is the Pixl.js PCB?

The Pixl.js measures 40 × 23 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Pixl.js?

45 components, from 30 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 Pixl.js design files?

From the freepixl/pixl.js 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 Pixl.js design in my own project?

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

Can I test firmware for the Pixl.js without the hardware?

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