Mokaboard: common questions

What microcontroller does the Mokaboard use?

The Mokaboard is built around the ATMEGA328P-AU, from the AVR/Arduino family.

How big is the Mokaboard PCB?

The Mokaboard measures 60 × 60 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mokaboard?

52 components, from 9 distinct parts. The full bill of materials is listed on this page.

Where can I download the Mokaboard design files?

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

Can I use the Mokaboard design in my own project?

The repository has no license, so all rights stay with troisiemetype. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Mokaboard 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.
