HANDS-EMG-BOARD: common questions

What microcontroller does the HANDS-EMG-BOARD use?

The HANDS-EMG-BOARD is built around the STM32L496RGT6, from the STM32 family.

How big is the HANDS-EMG-BOARD?

The HANDS-EMG-BOARD measures 80 × 54 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the HANDS-EMG-BOARD?

113 components, from 43 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 HANDS-EMG-BOARD 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 HANDS-EMG-BOARD 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 HANDS-EMG-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.
