The reasons for this unit, as opposed to using "off the shelf" unit, 1: cost about $10 US using import LCD, 2: This is the biggie . . . code formatting, I found several off the shelf backpacks all used different formatting, so if you are building a product, then you have to rewrite the code when you change vendors, 3: Control of the code.
