DC-DC Buck Converter Power Module

SKU: DFR0831

This is a 20W DC-DC buck converter power module with 7~24V input and 5V/4A output(Max). The high conversion efficiency and on-board 6 output ports make it suitable for connecting multiple devices like, large current servos, programmable LED strip, etc. The module integrates durable ceramic chip capacitors of large capacity on the ports and large inductor that can reduce heat generation. It is ideal for power supply scenarios like mechanical arm, servo robot, and programmable RGB LED strip, etc.
