  • at the moment (absolute beginner, no solder skills, etc.) i use a ready-to-use module from NOA Labs (available at Tindie.com )

    i did some light testing for power consumption

    • using the multimeter it takes around 20-25mA for a display refresh cycle, which needs ca. 1s
    • idle takes about 1,3mAh
    • i did not try it with setting deep sleep, but i am almost confident to say the deep sleep mode with max 5uA does not help here, it is the blue led which counts for the idle current draw
    • for the GDE021A1 the typical operating current is 8mA

    so far i am not able to just turn it off (still learning electronic switching with transistors) completely, which means it takes some current in idle mode - checked right now - 1,3mA (there is a blue LED which is always on when powered)

    it is possible to get the GDE021A1 display with SSD1606 controller without additional PCB, right now there is one seller at eBay
