Configuration for ESP32
{"NAME":"LilyGO T7 V1.5","GPIO":[1,1,1,1,1,1,0,0,0,0,0,0,0,0,1,544,0,0,0,1,0,1,1,1,0,0,0,0,0,1,1,4704,1,0,0,1],"FLAG":0,"BASE":1}
Flashing instructions for tasmota32 firmware.

The board uses an older version of ESP32 chip that requires a binary wih the PSRAM fix compiled in.

Compile with platformio env including these flags:

-DBOARD_HAS_PSRAM 
-DHAS_PSRAM_FIX 
-mfix-esp32-psram-cache-issue 
-mfix-esp32-psram-cache-strategy=memw

Template maps the JST SH1.0 4 pin connector GPIO21 and GPIO22 to I2C.

Pinout

Note: The difference between T7 V1.4 and V1.5:

GPIO16 and GPIO17 are replaced with GPIO25 and GPIO27. Board remains compatible with D1 mini expansion boards.
