uMyo is an open source wearable EMG sensor. It's single-channel, wireless, and collects muscle activity (EMG) data which you can then use in your projects. Works with any Arduino via nRF24 radio module, ESP32 boards, or our USB receiver base to send data to a desktop monitor app.

You can buy our base for uMyo PC connection here: Ultimate Receiver Base

Up to 12 uMyos can work at the same time, and they can use either dry electrodes (with a wristband) or wet electrodes. uMyo EMG sensors can be chained together with JST cables (PH2.0) to share power from a single LiPo battery, or a CR2032 to power one sensor (via battery holder PCB). There is also a LiPo charger board with a USB type C connector in each kit.

Specifications

  • Microcontroller: nRF52832 BLE SoC
  • Operational amplifier: AD8293 (additional bias compensation via firmware)
  • Mains noise filter: digital 50/60 Hz filter (auto detects mains frequency)
  • LSM6DSR gyroscope/accelerometer (low noise, 16-bit)
  • Short circuit protection: yes (PTC resettable fuse)
  • Antenna type: 5dB chip antenna
  • Charging: micro USB type C, via separate LiPo charger
  • Weight: 9 g (just the device with dry electrodes attached)
