Hi,

I was working on a thesis project on a portable ECG device, I checked these

MY CONFUSION: https://i.stack.imgur.com/CVJ1f.png & https://i.stack.imgur.com/qoMJl.jpg

CIRCUIT: https://raw.githubusercontent.com/gaodingpan/ECG-on-Teensy/master/CSE_EE%20474%20Lab%206_%20Analog%20Front%20End%20for%20an%20Electrocardiograph.jpg

https://www.instructables.com/Log-High-Speed-ECG-Data-Continuously-for-Over-a-Mo/

So it was basically biopotential->Amplifier->logging->displaying using Teensy(Programmable chip), Adafruit(Bluetooth Module), SPI LCD Screen, and resistors and capacitors.

I developed and assembled all except Teensy, adafruit, SPI LCD screen, as I don't have circuit on how to connect output to these 3 devices.

Can anyone share some other resources it would be very much valuable.

Thank You
