Pot board: common questions
What microcontroller does the Pot board use?
The Pot board is built around the ATmega328P-A, from the AVR/Arduino family.
How big is the Pot board?
The Pot board measures 77.1 × 132 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Pot board?
42 components, from 12 distinct parts. The full bill of materials is listed on this page.
Where can I download the Pot board design files?
From the mar0x/pq-4 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Pot board design in my own project?
The repository has no license, so all rights stay with mar0x. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Pot board 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.
