Big ESP32 + SX127x topic part 3

Well you can re-map the pins and it does work.

However, which LoRa driver are you using ?

The first diagram with the SD card mapped to its native interface was posted by yourself, bluejedi, “TTGO LoRa32 V2.1 rev1.6 versus TTGO LoRa32 V2.0 pin layouts”, back in October 2019. And very useful it is too. It corrects TTGO’s mistake in mapping IO0 and IO4 to power and ground for starters! Thanks.

Good catch.

The TTGO LoRa32 V2.1.6 pinout has now been corrected, enhanced and the file has been renamed.

Maybe this helps:

Below microSD connection details come from the TTGO LoRa32 V2.1.6 schematic diagram:
