Matters needing attention:
1. For long- operation, it is recommended to use the current within 2.5A and add the heat sink (output above 10W); As it is a step-down module, please keep the minimum 1.5V differential pressure to ensure stable output.
2. This module is an adjustable step-down module. The output voltage can be changed by adjusting the adjustable resistor the module. The input and output differential voltage is 2V, and the minimum output voltage is 1.25V.
3. The IN - (negative input), IN+(positive input), OUT - (negative output), OUT+(positive output) marked the m
