Question on the proper supply voltage for the Character Display module. The socket diagram on the overview tab on the product listing page indicates that pin 1 is 3V3, but appears to list pin 2 (5v) as unconnected. The specifications tab, meanwhile, lists the power consumption as 0 @ 3.3 V, 30 @ 5 V mA, which suggests that 5v is required.
I was testing this module with mBuino via a breakout, and was unable to get it to work on 3V3 supply, but works fine under 5V (via external power supply…mBuino does not provide enough current to run the display from the 5V pin, it would appear).
I’m assuming from the available info that the Character Display module runs on the 5V line, but the socket diagram suggests 3V3. Can someone from GHI confirm that it’s 5V, and if so, can you correct the diagram to indicate the proper 5V connection?
