Powering an I2C device via qwiic connector and another sensor via 3.3V rail - not working

Development Boards Artemis
1

Hi there,

I’m trying to connect a TMP117 sensor via qwiic and a Myoware muscle sensor via the 3.3V rail to an Artemis Nano. The Myoware is powered on, but the TMP117 is not, even though I can recognize that there’s an I2C device connected via a scanner. Is this expected behavior? If so, what’s the best way to get around this issue if I only want to use one Arduino board with one power source?

Looks like it was an issue with the qwiic connector. I used another artemis nano and it powered both devices.
