Myoware doesn't work

Good catch Tom.

Those solder joints look less than ideal as well. You should test them with a multimeter.

Tom, I used this connection scheme (this scheme from tutorial). Is it wrong?

This image is incorrect. The GND pin is the middle one on the sensor labeled “-”.

Tengo el mismo problema con el sensor, no me funciona, estoy leyendo todo lo que han comentado, pero sigue sin funcionar el sensor myoware, hay alguna solución?
