I'm trying to connect Max3012 to Raspberry PI. I actually tested:
- two Max30102 versions (?): one with 7 holes on one side and another one with 4 holes on one side and 4 holes on another AND,
- trying to connect it to 4B and ZeroW.
Connecting them as explained here:
3.3V (pin1) VIN
I2C_SDA1 (pin3; GPIO 2) SDA
I2C_SCL1 (pin5; GPIO 3) SCL
- (pin7; GPIO 4) INT
GND (pin9) GND
Obviously, enabled I2C via raspi-config, rebooted but when I run sudo i2cdetect -y 1 all I get is:
0 1 2 3 4 5 6 7 8 9 a b c d e f

I searched this forum and couldn't find a solution (already tried writing a totally fresh system to SD card, using/not using prototype board, using different wires, nothing helps). What am I missing?
