Note:

The touch chip is GT911, the manufacturer's default touch chip is 6336U. If you cannot drive the default chip, remember to specify this to the seller when purchasing.
Version V1.1 is placed on top of the 01-RTC motherboard, and version V1.2 is placed on the bottom of the 01-RTC motherboard.
Please pay attention to the wiring sequence when connecting, and pay attention to the top and bottom connections of the FPC connector. I myself reversed it several times!
