Ad8232 *2 Single-Lead, Heart Rate Monitor Front End
1333A TI 51K AEPE + BQZ TI K 483Y for eeg *1
Accelerometer: analog + lpv324 r2r opamp
https://github.com/BITalinoWorld/arduino-api No arduino c code. Only assembly C. → reverse engineer and redo code
Rev ecg related modules
Left i1 to a1 Empty 2chip A direct Ad Ad
Right Empty Empty Button Buzzer Acc sen(on analog!!)
2chip AVCC 3.2v Ref 1.6v Analog out
Same voltage for AD but only receive voltage on port 4 and 5
Same voltage for direct A/ diff opamp
Design need: 2 way ADC, 1 for acc, 1 for choice of ecg Some kind of wireless data stream
Thats it.
Rev onboard connection or make my own. Need FTDI breakout, reset management?
Plan: Connect ftdi and test upload. If work, good. Else if brick or doesn’t upload, make own. 11/27
