EMG SENSOR
About the EMG SENSOR PCB
EMG SENSOR is an open source PCB design by SonDinh23, published on GitHub under the GPL-3.0 license. It is a 4-layer board measuring 16 × 28 mm, with 43 components from 19 distinct parts.
Other key parts include the INA333xxDGK, MCP601-xOT, Pad 5, Pad_Battery and Pad_1. By type, the board carries 20 capacitors, 12 resistors and 11 ICs.
It belongs with the iot & wireless, wearables and sensors designs in this gallery.
From the project
Full-stack 6-ch dry-electrode sEMG wearable (ESP32/BLE, 1 kHz/ch, JSON presets) with DC removal + HPF/LPF + Kalman DSP and dual-path gesture control (Amplitude thresholds + 6-ch Radar-shape matching) + Flutter app; SNR>=8 dB, latency<=80-100 ms, >=85% online (4 grips)
The definitive pit stop for every PCB in the EMGBand/Hand Bionic stack. Each section tells you what the board does, how it talks to the rest, where to grab build assets, and what to check before you power it up—plus a gallery pulled straight from the committed files.
- Use forward slashes / in image paths; links are relative to this README. - Example: ``. - GitHub renders images once the PNG files are present; add new renders/photos in the matching board folder. - Prefer per-board READMEs or a PDF gallery? Say the word and we will scaffold it.
