Some components of ETX-DB-ATX are very sensitive to static electric charges and can be damaged by a sudden rush of power. To protect it from unintended damage, be sure to note these precautions:

Ground yourself to remove any static charge before touching the ETX-DB-ATX. You can do it by using a grounded wrist strap at all times or by frequently touching any conducting materials that is connected to the ground.

Handle your ETX-DB-ATX by its edges. Don’t touch IC chips, leads or circuitry if not necessary.

Do not plug any connector or jumper while the power is on.

2.3LCD Vcc Voltage Selector

The LCD interface connector CN1, CN2, CN6 can provide 5V or 3.3V power supply by selecting the JP4 to meet the different LCD requirement.
