Mynd Main: common questions

What microcontroller does the Mynd Main use?

The Mynd Main is built around the STM32F072RBT6, from the STM32 family.

How big is the Mynd Main PCB?

The Mynd Main measures 75 × 136 mm, has 4 copper layers and is 1.59968 mm thick.

How many components are on the Mynd Main?

560 components, from 141 distinct parts. The full bill of materials is listed on this page.

Where can I download the Mynd Main design files?

From the Prototype-Fund-Hardware/MYND-Hardware repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Mynd Main design in my own project?

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

Can I test firmware for the Mynd Main without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
