Upside Down Labs Muscle BioAmp BisCute DIY Kit - EMG Sensor Kit w/ Electrodes & Band

The Muscle BioAmp BisCute operates from a single supply voltage between 3.3V and 30V DC. This wide range allows it to be powered directly from most microcontroller boards (3.3V or 5V rails) or from a separate regulated bench power supply, providing flexibility for various project setups.

Connect the kit's output pin (after assembly) to an analog input pin on your microcontroller (e.g., Arduino A0). The provided BioAmp cable connects the three electrode leads (positive, negative, reference) to the sensor inputs. Power the board from your MCU's 3.3V or 5V pin and a common ground. The output is a conditioned analog voltage ready for ADC sampling.

This sensor is specifically designed for electromyography (EMG), amplifying the microvolt-level electrical signals generated by muscle contractions. It applies a fixed gain of x2420, boosting these weak signals into a robust 0–3.3V or 0–5V analog output range suitable for microcontroller ADCs. An integrated 72–720 Hz bandpass filter isolates the typical EMG frequency spectrum.

Yes, this is a DIY through-hole soldering kit. You must solder all provided components onto the PCB to build a functional EMG amplifier. If you prefer a pre-assembled version, consider the Muscle BioAmp Candy, which is the surface-mount (SMD) version of this sensor available pre-soldered.

The kit includes the BisCute PCB, all necessary through-hole components, a 50cm BioAmp cable, a pack of 3 Jumper wires, 3 boxy gel electrodes, and an adjustable sensor band. The system uses a 3-electrode configuration: positive (signal), negative (inverting input), and reference (ground) for differential amplification to reject common-mode noise.
