What is BioAmp v1.5?

It is a small size portable biopotential amplifier with a no code setup to record and listen to your muscle signals (EMG) non invasively. The best part is that it doesn’t require any microcontroller (like Arduino) to sample the signal. You just plug a 9V battery into the board, electrodes to the body, and an audio jack to a mobile/laptop, and you are ready to record signals from muscles (EMG) using audacity or Backyard Brain’s spike recorder app

What’s included in the kit?

• BioAmp V1.5 PCB
• All the passive components required in the PCB
• BioAmp AUX Cable
• BioAmp Cable v3
• 9V Snap Cable
• Muscle BioAmp Band (EMG Band)
• Boxy Gel Electrodes x 15

Note: Note: 9V battery is not included in the kit!

Assembling the Kit

Follow the steps below to solder all the components provided on BioAmp v1.5 PCB carefully. Follow this link for a complete tutorial on how to properly solder the components on any PCB.

How to use it?

To start using the fully assembled Upside Down Labs BioAmp v1.5 you require a 9v battery (not included in the kit). After doing that you have to connect

1. 9v Battery to power input.
2. Electrodes to the body using BioAmp Cable (see the connection diagram above).
3. 3.5mm BioAmp AUX cable to phone/laptop with recording software installed.

Note: You have to put the gel electrodes on the muscle you want to sense the signal from and use the alligator clips to connect to the Board.

Recorder software links, - Audacity for laptop (if you are using Linux you can get it from your distributions software repo) - Backyard Brains Spike Recorder for both laptop and smartphone

What makes BioAmp v1.5 special?

This board works on a single power supply (9v) and uses only one integrated circuit (TL074CN). It produces exceptionally clean output signals (if you are not very close to an AC Appliance Or a wall outlet) even without using any micro-controller board like Arduino. BioAmp v1.5 kit is also a certified open-source hardware project!
