Pixl.js oled: common questions

What microcontroller does the Pixl.js oled use?

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

How big is the Pixl.js oled PCB?

The Pixl.js oled measures 32.2 × 23 mm, has 4 copper layers and is 1.2 mm thick.

How many components are on the Pixl.js oled?

84 components, from 50 distinct parts. The full bill of materials is listed on this page.

Where can I download the Pixl.js oled design files?

From the xiaohail/pixl.js-oled repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Pixl.js oled design in my own project?

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

Can I test firmware for the Pixl.js oled 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.
