Note:
It is assumed that users have soldering skills and troubleshooting skills to assemble this kit. Buyers are advised that due to skills of user is involved in assembly it is not guaranteed every kit will end up being a working device. But we will make as much efforts as we can to approach that goal.
When soldering the SMDs, the temperature can not too high, otherwise there is the risk of bad soldering.
Please note that the direction of LED, LED long legs for the positive.
The second digital tube's point is in the bottom, is different with the other three points.
RT1 is a thermistor, RL1 is a photosensitive resistor. And the length of the pin should be enough to extend out of the shell.
The speaker is connected to the O1 and O2 of the voice module and is glued to the lower right corner of the circuit board with a double-sided adhesive tape.
Please be sure to finish soldering the back side of the components and then soldering the digital tube.
Specification:
Power: DC3V-DC5V (Adapter does not includes)
