Hi
I have trouble to find a datasheet and a correct pinout for this board. Google tells me that the pinout I find from Liligo has been wrong.
Due to massive use of ports in my project I strugle to get things to work.
Can any of you help me with a correct datasheet and or pinout.
Here is my needs for pins, and pic of board for info:
Thanks up front

have you tested basic device, e.g. is this LilyGO/TTGO-LORA32 your device? if not can you give a link to the device?

Good morning,
I am using a TTGO Lora T3_V1.6.1 board and I would like to connect a second Nokia 5110 display that works with SPI. The connection is impossible which pins should I use?

I tested all the configuration using the pins available for the SD card (which I don't use) but it still doesn't work.
I use the Adafruit PCD8544 library which allows you to configure the connection. For example I tested the pins: RST=34, CS=12, DC=35,DIN=15, CLK=14.
here is a qood video regarding esp32 pins
Andreas Spiess
He mention how to use 2 x SPI busses

Thanks for the link, but I can't find the solution.
Not all pins are accessible with the LILYGO Lora module.
