Mimas: common questions
What microcontroller does the Mimas use?
The Mimas is built around the PIC18F14K50, from the PIC family.
How big is the Mimas PCB?
The Mimas measures 66.1 × 62.2 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Mimas?
89 components, from 31 distinct parts. The full bill of materials is listed on this page.
Where can I download the Mimas design files?
From the numato/samplecode repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Mimas design in my own project?
The repository has no license, so all rights stay with numato. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Mimas without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug PIC firmware against it before you order a PCB.
