Heltec USB Interface Question

Hello,

Can the USBC connection on the Heltec Wifi LoRa 32 be used as an interface to a daughter board such as a Blues Wireless device? I understand it is meant for powering and flashing code primarily.

If this is not an option, is the only i2C access via the test pads 17 and 18 on the bottom to interface with a Blues Wireless board?

Thanks
