Mini mass prog bench: common questions

What microcontroller does the Mini mass prog bench use?

The Mini mass prog bench is built around the ATMEGA32U4_QFN, from the AVR/Arduino family.

How big is the Mini mass prog bench PCB?

The Mini mass prog bench measures 600 × 110 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Mini mass prog bench?

420 components, from 35 distinct parts. The full bill of materials is listed on this page.

Where can I download the Mini mass prog bench design files?

From the limpkin/mini_mass_prog_bench repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Mini mass prog bench design in my own project?

Yes, under the terms of its MIT license, which limpkin chose for the repository.

Can I test firmware for the Mini mass prog bench 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.
