Bonjour
I need to connect the Patient position sensor (the old one not the Pro version) directly to a standard Arduino and later to a Lolin D32 and I am looking for:

1. The cable pinout, I tried the schematic of the ehealth v2 but I didn't find it.

2. As the accelerometer (normaly a MMA8452Q) is working with 3.3 v for power and also for IC2 interface. Do I need to use resistor or a level shitter to protect IC2 interface or is already embedded in the belt circuit ?

3. Is IC2 pullout resistor need to be implemented or already embedded in the belt ?

Regards
