Myoelectric module MYO v1.2
(for registration of electromyographic signals)

MYO v1.2 is a ready for use compact myoelectric module, designed for registration and measurement of muscle activity.
Very easy to use with such microcontrollers as Arduino, STM32 and Teensy. To receive a signal, it is enough to power the device with a voltage of 5V (no more than 5.5V) and connect the output signal to a ADC.

We provide free libraries for using MYO v1.2 with Arduino, Teensy and STM32, also we provide sketches for visualisation signals by Python and Matlab.

Features:

• Operate voltage is 4.5 - 5.5 V. Typical 5.0 V.
• Low supply current 3 mA.
• Two analog output channels: OUT_3.3V in the range 0 - 3.3 V and OUT_5V in range 0 - 5 V.
• Base gain is 500 V/V, can be increased by 8 additional Gain Selections: x1, x2, x4, x5, x8, x10, x16 or x32 V/V
• Serial Peripheral Interface (SPI) gain selection.
• 8 - 100 Hz filter.
• Dry skin contact.
• Stainless steel electrodes.
• Size of module 44x15.5x8.5 mm (accuracy to 0.2 mm), scanning electrodes 10x10 mm, grounding electrode 10x5mm.
• Wire length ~ 50 cm
• Libraries for Arduino, STM32 and Teensy
• Examples of sketches for signal visualisation by Python and Matlab

NOTE: this product is NOT a medical device and should not be used to diagnose or treat medical conditions.

If you plan to use the module with a plugged-in PC (connected to the household power supply), we recommend purchasing a USB Isolator: it will reduce the interference caused by the household power supply and also make the connection safe.
