Polly power: common questions
What microcontroller does the Polly power use?
The Polly power is built around the Arduino_1pin, from the AVR/Arduino family.
How big is the Polly power PCB?
The Polly power measures 134.8 × 53.3 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Polly power?
53 components, from 30 distinct parts. The full bill of materials is listed on this page.
Where can I download the Polly power design files?
From the icnagy/polly-power repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Polly power design in my own project?
The repository has no license, so all rights stay with icnagy. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Polly power 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.
