DFR0831

SKU:DFR0831 (https://www.dfrobot.com/product-2240.html) (https://www.dfrobot.com/product-2240.html) Introduction 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 inductor that can reduce heat generation. It is ideal for power supply scenarios like mechanical arm, servo robot, and programmable RGB LED strip, etc. Feature Large current output High conversion efficiency Onboard 6 Outputs for connecting large-current servo, programming LED strip, etc. Specification Input Voltage: 7~24V Output Voltage: 5V Output Current: 0-4A(Max 5A, heat dissipation is necessary) Conversion Efficiency: 90% Output Ripple: ＜100mV Output Accurancy: ±0.1V No-load Current: ＜1mA Operating Temperature: -40°~+85°C Operating Humidity: 20%~90% Dimension: 43.5x20.3x5.5mm / 1.71x0.80x0.22” Board Overview Num Label Description 1 IN- Input - 2 IN+ Input + 3 OUT- Output - 4 OUT+ Output + 5 G GND 6 5V Output 7 S Servo controlling signal Dimension Tutorial R i Requirements Hardware DFRduino UNO R3 (https://www.dfrobot.com/product-838.html) (or similar) x 1 DC-DC Buck Converter Module x1 FIT0750 5V RGB Programmable LED Strip x1 Servo x1 Software Arduino IDE (https://www.arduino.cc/en/Main/Software) Connection Diagram Connecting with 5V RGB LED Strip Note: The method below only suits the situation that higher brightness is required or multiple LED strip lights need to be cascaded. For low-current modules, there is no need to connect this buck converter since Arduino UNO can directly supply power for them. Connecting with servo Note: The port S of the converter can connects 6 servos. FAQ For any questions, advice or cool ideas to share, please visit the DFRobot Forum (https://www.dfrobot.com/forum/) More Documents Get DC-DC Buck Converter 7~24V to 5V/4A (https://www.dfrobot.com/product-203.html) from DFRobot Store or DFRobot Distributor.
