Attention :
This is a high-power boost module. Please pay attention to the following when using:
1 The power supply must be sufficient. If the module needs to output 17W power, the power supply must be greater than 25W.
2 The power and boost module leads must be thick enough (can pass 10A) and soldered well.
3 Use a multimeter to directly measure the ''Vi GND'' port to determine if the power is sufficient. If the voltage is lower than the power supply 1V, the power supply is insufficient or there is no good connection.
4 Input voltage can not be greater than the maximum input range
5 Output power can not be greater than the maximum load for a long time
6 Input power must be greater than the output power, because the power consumption of the module itself
