BioAmp v1.5 is a single chip Bio-potential amplifier for recording any Bio-potential signal non-invasively. It's compatible with Backyard Brains Spike Recorder, which you can use to record and visualize all the Bio-potential signals.

This PCB is the starting point of our build, solder components as per the instructions below to get your own BioAmp v1.5 ready to record BioPotential signals. Keep this interactive BOM link handy to help you with the build process.
We will start with all the resistors first, for this step you solder a 1k resistor at R11 as shown in the interactive BOM. The image below shows the exact placement.
Solder 6 x 10k resistors at R1, R2, R5, R6, R7, and R8.
