A Little Backstory:
I recently received a spare small 1.8 (the kit self-proclaimed it as HD though I'm skeptical due to the size) screen I happened upon from an arduino kit I got as a present. Note that the vendors of that kit were kind enough to provide what I assume is normally clear manual and or spec sheet. Unfortunately for me, I don't understand the language, but after searching the web with the info present on the board and the size of the screen itself I was able to pin this down as Chinese generic Arduino product that is currently being sold on Temu. It has a Video Driver IC: ST7735S and the information they provide [included below as numbered points] seems a tad off, maybe, I'm not sure 100% myself.
(Staff and Moderators, I looked for threads with this model screen but couldn't find one, so I had to create one. I am new to this forum and to lcd screens in general so I apologize if there is a thread with a similar model and question)
Anyways my actual question:
I was wondering just out of curiosity if this can be wired to accept either rca or hdmi video input without the use of an arduino. As I currently do not have the arduino shield to connect the board, nor am I serious enough to consider buying a shield or actually using this in a portable project due to its size, and scruples I have surrounding this product. Except maybe as a test screen while I await the 8 inch lcd screen and other parts I ordered to come in.
Sidenote: If you decide to buy the kit from Temu, which seems to be exactly the same as the one I got. Test the pins before for ease of soldering with good flux and solder with higher temps. Otherwise you may just want to pass on soldering the pins provided onto the board, the ones I got were made out of some sort steel (it was magnetic, plus it dented & broke my pin cutters' tip) that even when lightly sanded and I applied a liberal coat of flux would just not solder easily. Even when cranking the heat on my iron to 700 F, I still got poor joints that I'm just going to undo.
