There seem to be a lot of these around, but no clear instructions for hooking them up and using them.
The chip on the back says this:
The pinouts with headers are; VCC GND GND NC NC LED CLK SDI RS RST CS
There are unsoldered headers too 1-RST 2-CS 3-D/C 4-DIN 5-CLK 6-VCC 7-LED 8-GND
The package it came in said 1.44 Arduino IC: ST7736 128x128 SKU QDM144SPINT7735RA Barcode 6013801144020 one one side, and 19/6 24/50 5401105 9FM06-05-0102 on the back.
The pin in it labelled “RS” is equivalent to pins named CD, DC, D/C, RS, or A0 on other devices.
Wire it as follows (TFT => Arduino Nano):
CLK => D13
SDI => D11
RS => D9
CS => D10
RST => D8
LED => 220ohm => +5v
Declare it in your code like this:-
Ucglib_ST7735_18x128x160_SWSPI ucg(/sclk=/ 13, /data=/ 11, /cd=/ 9 , /cs=/ 10, /reset=/ 8);
And you’re good to go!
