Are there arduino boards with integrated OLED displays available for purchase? I have been working on a handful of projects and soldering on OLED displays to all of them. It only involves four wires using I2C, but an integrated one-board solution is just much cleaner and solid. I was thinking something like the integrated ESP8266/ESP32 boards now available for $10-15, but could not find any using the Arduino.
Alternatively would it be possible to order a small run of custom assembled boards at a reasonable cost (something like a Pro Mini combined with a 128x64 OLED)?
