Troubleshooting Guide

1) Check whether your power source is connected properly. Also check the voltage level of your battery.

2) Refer to the Instruction Manual / Component List that came together with our product. Make sure that all components are placed at the correct positions and take note of the polarities of the components (positive and negative).

3) Check your soldering. Make sure that all the legs of the components are soldered firmly on the PCB (Printed Circuit Board). Check with our soldering guide for more information on the correct method of soldering.

4) Check for short-circuit. Scrutinize the back part of the PCB board to see whether there are any copper lanes connected together by mistake whilst soldering. Metal fragments stuck to the board may also cause a short-circuit. Make sure the back part of your PCB is always kept clean.

5) Check for any sign of component damage. Damage to components may occur if the circuit is connected incorrectly or during soldering. Take special care when soldering components such as ICs and Transistors.

6) If your project still fails to function, you can contact out technical staff for specific guidance / advice.
