The display cycles through the digits 0-9 and the hex=20 letters and finally the two dots in center. The decimal points for each digit are not present on this display so=20 what I did was to paint over one of the dots in the center so I have a=20 99.99 display . These displays are limited by the decimal point issue,=20 but they are so easy to use that I can overlook that. Glad to hear it works at 3.6V , I tried 3.3V and couldn't get a display.
