Cheap 2X16 red/black LCD tests
We got our hands on a few cheap 2×16 red/black LCDs of eBay for $5 a piece, these are the same LCDs from the unboxing video. In preparation to build the soldering iron driver, we tested them out with the Bus Pirate LCD adapter and the USB LCD Backpack. Initially we were worried that the red on black LCD would need a negative voltage supply, contrary to the advertisement, but it works great on a simple supply.
The USB LCD Backpack is available for $16.95 at Seeed Studio.This entry was posted in testing and tagged 47780, LCD, USB LCD backpack.
