Hello, the OLED display on my RS232 WIModem is faulty. It works intermittently, mostly off.
It's definitely the display because I connected a different white one and it worked fine. But this one has the "VCC and GND" pins reversed, so it's not compatible.
And what is its actual size?
I ordered a 1.3-inch display (from AliExpress), but it's too big.
What is its actual reference number? (It's difficult to find the layout of the "Vcc-Gnd-Scl-Sda" pins).
I can't send it to you because I'm in Europe. Thank you.
