Final handsEMG: common questions
What microcontroller does the Final handsEMG use?
The Final handsEMG is built around the STM32L496ZGT6, from the STM32 family.
How big is the Final handsEMG PCB?
The Final handsEMG measures 85.9 × 94.4 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Final handsEMG?
200 components, from 104 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 Final handsEMG design files?
From the blakep7/HANDS-EMG repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Final handsEMG design in my own project?
The repository has no license, so all rights stay with blakep7. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Final handsEMG 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.
