Feature:
This kit is designed for SMD soldering practice only.
No need manual, put the right element to the right position as follow.
Battery: 3*AA battery (package does not includes)
Soldering Note:
SMD components are relatively small, please note that do not lose, light-emitting diodes, diodes, chips have direction, pay attention!
The LED green dot for the negative, you can use a multimeter diode lights light-emitting diodes, red pen for the positive, the black end of the diode is negative.
When using power supply must pay attention to the power supply positive is connected +, negative connected -, the supply voltage is 5V.
