PowerMonitor: common questions

What microcontroller does the PowerMonitor use?

The PowerMonitor is built around the ATTINY88-PU, from the AVR/Arduino family.

How big is the PowerMonitor PCB?

The PowerMonitor measures 101.4 × 50.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PowerMonitor?

43 components, from 32 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 PowerMonitor design files?

From the kk6axq/PowerMonitor repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the PowerMonitor design in my own project?

Yes, under the terms of its GPL-3.0 license, which kk6axq chose for the repository.

Can I test firmware for the PowerMonitor 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.
