PwrModule: common questions

What microcontroller does the PwrModule use?

The PwrModule is built around the ATTINY424-SS, from the AVR/Arduino family.

How big is the PwrModule PCB?

The PwrModule measures 25.9 × 62.3 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the PwrModule?

21 components, from 11 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 PwrModule design files?

From the CIDCO-dev/Poseidon 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 PwrModule design in my own project?

Yes, under the terms of its MIT license, which CIDCO-dev chose for the repository.

Can I test firmware for the PwrModule 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.
