Power: common questions
What microcontroller does the Power use?
The Power is built around the Arduino Interface, from the AVR/Arduino family.
How big is the Power PCB?
The Power measures 115 × 75 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Power?
51 components, from 29 distinct parts. The full bill of materials is listed on this page.
Where can I download the Power design files?
From the simle-stardust/PCB repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Power design in my own project?
Yes, under the terms of its MIT license, which simle-stardust chose for the repository.
Can I test firmware for the 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.
