README
README.mduEMG - 4-channel EMG device
This repository contains PCB design, firmware and PC program for analysing data (that one has hardly readable code for now, it's a work in progress with thousands lines of code dedicated to various signal processing approaches with only small part of them used in current version)
Firmware is in relatively good state. It depends on our nrf library: https://github.com/ultimaterobotics/urf_lib and requires bootloader: https://github.com/ultimaterobotics/uECG_bootloader

Questions
How big is the UEggMG v3b PCB?
It measures 81.7 × 372 mm and has 2 copper layers, 1.6 mm thick.
What parts does the UEggMG v3b use?
80 parts, built around the AD8608AR, 74AHC1G32GW, BMI160 and BAV99. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the UEggMG v3b KiCad files?
From the ultimaterobotics/uEMG repository on GitHub, at the commit this page was made from: the board is pcb/uEggMG_v3b.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the UEggMG v3b design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
