BrainEnch: common questions

What microcontroller does the BrainEnch use?

The BrainEnch is built around the STM32L151CXTX, from the STM32 family.

How big is the BrainEnch PCB?

The BrainEnch measures 50 × 57 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the BrainEnch?

59 components, from 44 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the BrainEnch design files?

From the Kreyl/nute repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the BrainEnch design in my own project?

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

Can I test firmware for the BrainEnch 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.
