Each IO pin is preconfigured with IO_MUX functionality, which means you can use any GPIO as I2C or SPI pins. You just need to define these pins in your code. However, it’s important to note that once a pin is used, it may affect other functions associated with that pin. What are the connection options for HT-HC32? include Wi-Fi, Bluetooth, and Wi-Fi HaLow, with an onboard 2.4 GHz patch antenna for Wi-Fi and Bluetooth, as well as a reserved IPEX (U.FL) interface for the HT-HC01 Wi-Fi HaLow module.
