    I suffer with lung disease so monitor my sats and heart rate regulaly and being a retired electronics engineer saw this module and the AD 8232 module so hooked them up to my esp32 board and did some comparisons with my finger clip on spo2 monitor both read exactly the same build quality is good

    It does what it should. Three resistors have to be removed to work with the arduino. (the only three on the board)
