1 month ago Thank you for the hint. I have not encountered OLEDs with a different pin configuration before. I am currently traveling and have a very busy schedule. Once I have a bit more time, I will add a corresponding note.
Hi, I just build this device. Worked on first try! (nice job)
Sort of.
The OLED exists in multiple variants. I2C and SPI. While i bought the correct one 4pin, the pinout was VCC GND I2c i2c. Your pinout is GND VCC I2c I2c.
Probably worth mentioning for people interested in building.
(or maybe add 2 0R resistors on bottom that can be mounted as || or = depending on source of oled)
