Welcome to our shop, we have new products on the shelves every day. If you like DIY, please pay attention to it in time. Package includes: 1 piece *The product will be upgraded constantly, the appearance and color may be changed, please don't mind. And take a consideration before place the order if you have request for color or appearance. Module highlights: 1. On-board voltmeter, voltmeter can be self-calibrated, there will never be a problem with voltmeter inaccuracy! Module performance and features: ● With voltmeter display and voltmeter self-calibration. A more advanced voltage microprocessor is used, the voltmeter error is ±0.05V, and the range is 0~40V. (To ensure the accuracy of the voltmeter, please ensure that the input voltage is above 4.5V) ● Touch the button to switch the measurement input or output voltage, and the indicator light shows which voltage is being measured, and save the settings, even if it is powered off and then on. ● The voltmeter can be turned off, and it can be easily achieved by tapping the left button when it is not needed. ●With terminal block, no soldering iron can be used conveniently, and the wire bonding point is retained. ● Input voltage is 4.0~40V. (The input voltage must be 1.5v higher than the output voltage) ● Adjustable output voltage range from 1.25V to 37V continuously adjustable. (The input voltage must be 1.5V higher than the output voltage) ● Output current 3A, it is recommended to use within 2.0A, high current needs to strengthen heat dissipation. ● Output power 20W, more than 15W, please strengthen the heat. ●High conversion efficiency, with an average of 88% (efficiency related to input and output voltage, current, and voltage difference) ●With reverse connection protection, reverse connection does not burn ● With overheat protection and short circuit protection ● Size 6.1*3.4*12cm (length * width * height) ● Weight: 22g Application range: This module can be applied to the buck field where the input voltage is higher than the output voltage, such as battery, power transformer, DIY adjustable power supply, 24V car pen power supply, industrial equipment step-down, 12V to 3.3V, 12V to 5V, 24V to 5V, 24V to 12V, 36V to 24V, etc. Onboard voltmeter self-calibration method: 1. When the on-board voltmeter displays the output voltage, press and hold the right button for 2 seconds to release, the voltmeter and the output voltage indicator "OUT" flash synchronously. At this time, the output voltage adjustment mode is entered; similarly, the voltmeter is displayed. When inputting the voltage, long press the right button for 2 seconds and then release, the voltmeter and the input voltage indicator "IN" flash synchronously, then enter the input voltage adjustment mode; 2. Tap the right button to increase the voltage by one unit. Tap the left button to lower the voltage by one unit. Since the voltage of one unit is less than 0.1V, you need to press 1-5 times to see the voltmeter. Changed by 0.1V, the specific continuous button press depends on the currently displayed voltage value, the higher the current display voltage, the fewer the number of presses; 3. After the voltage adjustment is completed, press and hold the right button for 2 seconds and then release. At this point, the voltage calibration mode can be exited, and all parameter settings are automatically powered down. Note: This adjustment method only needs to be calibrated once to get accurate voltage value over the entire voltage range. This function is designed to meet your higher precision requirements. Please feel free to use it.
