I’m curious about doing an OLED drop-in for an Alesis Micron, funnily enough, and stumbled across this thread. Comparing the datasheet you supplied for a compatible micron led to the Winstar offerings I identified this module that has pretty close measurements and appears to communicate with the same controller:

My research elsewhere led me to find that the correct replacement part is the WH1602m (WH1602M - WINSTAR) and the micron utilises the 4-bit 6800 protocol.
Any advices, or do you reckon the WEH001602a I linked will work?
