Hi Jim,

Please check the pinout of the OLED displays you have. There are some models which are Vcc, GND, SCL, SDA, these ones even if you correctly connect them with wires they will not work with the AQM II.

The correct model for AQM II will look like those on the pictures below

Werk, 
The ones i have are marked correctly for the pin connections but have no details on the back. Could you please advise me of your supplier and I will order them.
Regards
Jim
