How to use MP3429 Low-Ripple DC-DC Step-Up Boost Power Supply
The module features multiple voltage outputs (5V, 9V, 12V, 15V) configured on the board. To convert to the desired voltage output, simply solder the corresponding jump point. Connect the input power voltage to pins 5 and 6 (VIN), and the output power voltage to pins 7, 8, and 9 (VOUT). The module can be enabled via the EN pin (pin 4). Ensure that the input voltage is within the specified range and the current does not exceed the module's maximum input current limit.
