Hello all,
I am currently trying to use the Gravity: Offline Language Learning Voice Recognition Sensor with my Arduino nano 33 IoT however every time I use it the nano with specifically just this voice recognition module I get the "No device found on COM5" error. I tried it with the same usb cable and still had the same issue, tried resetting the board and also no luck. I tested the board with a simple LED blink sketch and it worked no problem. This problem only arises when using the voice recognition module. I have a feeling it has something to do with the SDA/SCL pins I am using as this is the first time I have used them on a nano and I2C. Also probably worth mentioning I tried this circuit and program on the UNO and it worked just fine. Any help would be greatly appreciated, below is the code and picture of the circuit. Also I will add a link provided by the manufacturer that shows other details about the product. SKU_SEN0539-EN_Gravity_Voice_Recognition_Module_I2C_UART-DFRobot
