The I043 TX0 should be connected to RXD, and I044 RX0 connect to TXD
Thanks for answer. Some people talks that XY-485 module must be connected as RX-RXD, TX-TXD. Other people talks that ESP32 hardware UART is not compatible with XY-485 module. https://aliexpress.ru/item/32857507366.html
What problem in that?
I have tried to connect XY-485 module to CrowPanel thorough Arduino Nano:
XY-485 UART <-> Arduino Nano Software Serial2 <-> Arduino Nano Hardware Serial UART0 <-> CrowPanel UART0.
Arduino Nano works in transmitter-receiver program mode.
And this system works! Dual channel transmission and receiving works fine. Why CrowPanel UART0 incompatible with XY-485 UART based on usual MAX485 chip?
Hello ,
We want to buy an 7 Inch Display - DIS08070H. But On Mouser.in & Digikey.in it's available only without Acrylic case.
We need with Acrylic case. Please share the actual part no. which is available with Acrylic case either its with 7inch or 10 inch.

I have tried to connect RXD pin of XY-485 to laptop thorough USB/UART convertor. Data have been received successfully .

No ideas?

Please answer me!
The schematic https://www.elecrow.com/download/product/CrowPanel/ESP32-HMI/7.0-DIS08070H/7.0-DIS08070H-SCH&PCB.zip that is linked from the website https://www.elecrow.com/wiki/esp32-display-702727-intelligent-touch-screen-wi-fi26ble-800480-hmi-display.html still shows the resistance as 22R. I measured 470R on a recent board, but 22R on an older board that does not have the I2C port.
Furthermore, the "Update Record" at https://forum.elecrow.com/discussion/672/esp32-display-update-history does not mention the resistor value change.
Please update the documentation so we don't waste so much time with wrong information.

@vdmerwej Have you found any solution of this rx pin?
