  H!
  CrowPanel ESP32 Display 3.5 Inch Display

  I need an advise regarding "CrowPanel ESP32 Display 3.5 Inch Display".
  I would need to connect to 2 (two) 485 devices and I would need at least 1 input PIN and 1 output pin.
  One more question: How many free pins I can use for my stuff ?
  Thanks!

  Hi, i'd like to post please:

  I just got a CrowPanel Advance 5.0-HMI ESP32, version 1.1

  Three questions if I may:

  1. Do you have the schematic file of version 1.1? I only can find 1.0 version.
  2. In the google drive for this board for PlatformIO (https://drive.google.com/drive/folders/1Qw7hdW862upBigarI11btgl4cQkr0vpe) i can only see 1.0, 1.2 and 1.3 version. All codes reference a TCA9534 and or STC8H1K28. am i correct in understanding the 1.0 has the TCA9534 for backlight and 1.1 and above have the STC8H1K28?
  3. In the documentation its mentioned that you can send 0x05-0x10 to the STC8H1K28, but in the code (2.0 and 3.0) i see 0x18 and 0x19 being sent, what is this for? is there some more documentation about the STC8H1K28?

  Thanks.
