Aloha everyone - I'm trying to power the 1.44" LCD with the Micro-Lipo Charger, and not having any luck. Shouldn't it just be 5V to Vin, and GND to GND?

Re: Driving 1.44" LCD with Micro-Lipo Charger
Are you using a microcontroller to draw an image?
I would not expect to see anything just by applying power as you have described.
Using the Micro-Lipo charger is an odd way to power a circuit. I don’t think that will work unless you are plugged into USB.

Aloha, thanks for the feedback!
As to the microcontroller, no, I'm trying to make this as small/self-contained as possible. All I'm looking to do is have the display cycle through BMP images on the MicroSD. It isn't powering the display whether I have the charger plugged in or not.

The MicroSD card is a good place for storing bitmaps (BMPs), but that is all it will do. You must have a controller connected to this display to "play" or "draw" the bitmaps on the LCD.
