DigiPot Evaluation Board: common questions
What microcontroller does the DigiPot Evaluation Board use?
The DigiPot Evaluation Board is built around the ATmega32U4-AU, from the AVR/Arduino family.
How big is the DigiPot Evaluation Board?
The DigiPot Evaluation Board measures 114.3 × 163.2 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the DigiPot Evaluation Board?
71 components, from 36 distinct parts. The full bill of materials is listed on this page.
Where can I download the DigiPot Evaluation 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 DigiPot Evaluation 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 DigiPot Evaluation 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.
