I would like to build (around 150 + ) digital labels, using an LCD 16x2 or even a 2.2" 18-bit color TFT LCD display with microSD card breakout - HX8340BN
These are things that I would like to achieve;
Run off Battery for minimum 5 hours
Compact, need to be placed on counters for customers to see
Be able to change what is displayed on the label, either wireless, RF, or via Card
It would be great to get some feedback, ideas and help with a project like this.
