Field notes
The hardware description pairs two ADS1299 front ends on one SPI bus with an ESP32-S3, then routes data over isolated USB-C or Wi-Fi UDP into Lab Streaming Layer. It gives separate sEMG and EEG profiles, and shows a Python recording example that exports 16-channel data with timestamps to HDF5. Listed tiers range from a PCBA to a cuff-and-electrode kit and a lab bundle framed around camera or motion-capture synchronization.
