From the project
PCB designed with KiCad for OLED 2.42" display.
I use this pcb to connect 2.42 inch displays from Aliexpress to either my SHC build or the ESP32 dew heater. Look for 2.42" 128x64 SSD1309 displays and the assoc. metal frame.
Best case you can use all displays equals to 25/unit. Worst case you just need one and can't share the cost of the other four equals to 125.
