EMG-HW-MainBoard: common questions
What microcontroller does the EMG-HW-MainBoard use?
The EMG-HW-MainBoard is built around the STM32WBA63CIU6, from the STM32 family.
How big is the EMG-HW-MainBoard PCB?
The EMG-HW-MainBoard measures 95.3 × 62 mm, has 4 copper layers and is 1.16 mm thick.
How many components are on the EMG-HW-MainBoard?
123 components, from 47 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 EMG-HW-MainBoard design files?
From the N-Pulse/EMG-HW-MainBoard 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 EMG-HW-MainBoard design in my own project?
Yes, under the terms of its CC-BY-4.0 license, which N-Pulse chose for the repository.
Can I test firmware for the EMG-HW-MainBoard 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.
