  1. Please confirm whether the screen specification book screen supply voltage is correct, whether the board’s corresponding power supply can meet the maximum working current of the screen.
  2. Please use a multimeter to confirm that the power supply selected by the jumper cap is correct.
  3. When connecting the 6 / 8-bit LVDS screen cable, install it near pin1.

No.

HUIDU HD-M21 KEY Interface (extension) and definition
1 group of 485 communication interface, which can support common 485 interface equipment on the market. The level of the interface is 5V. If the level of the connected interface is higher than 5V, there must be an isolation circuit or a level conversion circuit, otherwise the main control and equipment will be burned out.
  1. 1. Whether the voltage of the 485 interface matches.
  2. Whether the connection of 485A and 485B wires is correct.li>
