Prrpls406: common questions

What microcontroller does the Prrpls406 use?

The Prrpls406 is built around the ATTINY406-MNR, from the AVR/Arduino family.

How big is the Prrpls406 PCB?

The Prrpls406 measures 8 × 8 mm, has 2 copper layers and is 0.6 mm thick.

How many components are on the Prrpls406?

20 components, from 5 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 Prrpls406 design files?

From the jimktrains/prrpls 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 Prrpls406 design in my own project?

Yes, under the terms of its AGPL-3.0 license, which jimktrains chose for the repository.

Can I test firmware for the Prrpls406 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.
