Edm control board: common questions
What microcontroller does the Edm control board use?
The Edm control board is built around the SI8641BB-B-IS, from the STM32 family.
How big is the Edm control board?
The Edm control board measures 240 × 100 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Edm control board?
58 components, from 39 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 Edm control board design files?
From the strombom/EDM repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Edm control board design in my own project?
The repository has no license, so all rights stay with strombom. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Edm control board 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.
