I’ve used a 16X2 serial Red on Black LCD as the display in astronomy projects. Great but I’d love to have a larger screen. I noticed someone else had asked about a Red on Black version in the comments section for a 20X4 serial LCD but have not seen an answer.
At a guess a lot of astronomy hackers would love to have an affordable serial screen which did not mess up night vision.

I’ve found a 20*4 red on black LCD. I’ve ordered 2 to try them out but would love to see a serial LCD board added.

I’ve done some basic power up and limited screen output using the display matched to a Sparkfun Serial LCD Backpack. So far so good although I’ve not done any coding yet to use the extra display size.
The display is an RT204-1 (VER2.0). Very hard to find much information about them on the web or other suppliers.
