Laowang stn/cstn and 1.8in tft screen adapter board

All pull-down point resistors are 10k.
The transistors are s8050
backlight current-limiting resistors. The ones here are directly driven by the power supply. I
use 100R.
If controlled by a microcontroller, I recommend 1k~10k
or you can choose to replace the appropriate MOS tube.
100R may burn out the microcontroller
capacitor 0.1uf~ 10uf is available.
All components are subject to description.
Do not refer to BOM

Lao Wang’s stn screen
picture and the corresponding welding method
for the transfer chip using 74hc595
program are shown below (thanks to the boss an_ye)
PCB space design problem The screen is close to the soldering pad.
The screen printing of this screen It's not accurate. The actual screen is larger than the screen printing. If you have high requirements for
screen printing accuracy, you can still use it if you don't change it .************************ *************************** ************************* **************************** Lao Wang’s cstn screen picture and corresponding welding method. The adapter chip uses 74hc595 , which may be the cause of the program display effect. Pulling a horse can light up anyway. The procedure is the same as above **************************************** **************************************************** ​************* Normal 1.8in tft screen pictures and corresponding welding methods do not require a transfer chip program? st7735 ************************************************* ****** ************************************************ *********** The program mentioned above: the library and attachments in the picture. Of course, you can also use the pio project I packaged in the attachment to directly connect the high-level backlight RD to other pins of vcc. For st7735 RD, you don’t need to connect it ; RS is D/C.
