      Hello,

      Can I power up and use the STWI080WT-TTL with 5VDC supply instead of 12VDC?

      One of our mcu boards can only supply 5VDC.

      How do I modify the LCD to do this please?

      Thanks.

      There is a 5V short contact on the back of the LCD. It can supply power to the LCD with 5V by using the solder short. However, it should be noted that only 5V power can be used after the change

      Hi Bowei,

      Ok thank you for your reply. I will solder this 5v link.

      The power connection to the LCD shall be the same wires as in the 12V?

      Thanks again.

      If the 5V spot is welded, 5V can only be used to connect the VIN of LCD

      If the 5V connection point is disconnected, the VIN of LCD can be connected with 12V
