TinyLily / Tinylily LRA Module Issue
« on: October 27, 2022, 01:31:18 PM »
Hello, I am running into an issue with the DRV2605 in audio to vibrate mode. When the microcontroller is hooked up to the USB connection and the rest of the circuit is hooked up to the battery, it works fine. However when everything is hooked up to the battery, the LRA motor just vibrates continuously.

Circled in the photo are the signal and ground wires for the audio signal that goes to the DRV2605 module. With the microcontroller hooked up to USB they read 0v normally, but with the battery connected to the microcontroller they are getting 3.3v continuously.

I tried this same circuit with the Seeed Xiao and the Adafruit haptic module and ran into the same problem.


Any help is appreciated!
