MYO-kit v1.1 is a compact myoelectric (EMG) kit designed for quick devices development operated by 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 solder kit and power it with a voltage of 5V (no more than 5.5V) and connect the output signal to an ADC.

We provide free libraries for using MYO-kit v1.1 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: OUT1 in the range 0 - 3.3 V and OUT2 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 boards: 33.2x10.0x3.3 mm (accuracy to 0.2 mm)
• Wire length ~ 50 cm
• Libraries for Arduino, STM32 and Teensy
• Examples of sketches for signal visualisation by Python and Matlab

If you plan to use the kit 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.
