Hello everyone! I recently decided to venture into the Heltec WiFi LoRa 32 V3.2. Unfortunately, it’s not what I expected; however, I have still managed to make progress on my project. At this point, I want to connect a microSD adapter module, which communicates via the SPI protocol. I’ve been checking the pin map, but I haven’t been able to find which external pins I can use for this connection (understanding that LoRa also uses SPI). I was hoping to use it anyway.

The use of the SPI interface to drive a µSD card reader on several processors, including the V3 modules, is covered in this discussion on the subject.
