I want to try to create a PWV speed gate by measuring femural artery pulse arrival delta time using two max30101 sparkfun sensors at a fixed distance apart, resulting in an estimate of PWV.
First snag, it appears the all sparkfun max30101 sensors have a factory loaded i2c address of 0x57.
I was hoping to avoid the more expensive sensor hub, max32664, that appears to allow multiple i2c circuits.
Any ideas how to alter the i2c address on one of the sensor boards?
I am using a Seeeduino Xiao controller, should I be able to add a second i2c circuit to it?
