Chapter 8--Troubleshooting
Question 1 – The power adapter requirement of the board.
The board voltage and the LCD voltage are 2 different parameters.
The board can be worked from +5V to +12V with 3.0A current.
Question 2 – The LCD panel voltage
The LCD voltage only can be supplied by the board’s jumper with only +3.3V +5.0V +12.0V.
Most of LCD panel works at +3.3V. Normally, the board’s jumper has been jumped to +3.3V and
please don’t jump it again. Or else, the LCD will be damaged at +5.0V/+12.0V.
Question 3 – How to confirm all the connections are in good condition.
First of all, please do not input any signal cable.
Then power on the board via keyboard power ON/OFF button.
The following image can be shown on the LCD. That means the board kits and LCD are in
good condition. Then you can start use it via plugging in the signal cable.
