2Pcs LM2596 Adjustable DC-DC Buck Converter Module with Voltage Meter
- Adjustable LM2596 DC-DC Buck Module: This regulated power supply module uses the LM2596 step-down design to convert a higher DC input voltage into a lower adjustable output voltage. It is suitable for DIY power supplies, electronics testing, LED projects, device repair, and prototype circuits.; Wide Input and Output Voltage Range: The module supports a 4.0V to 40V DC input and provides an adjustable 1.25V to 37V output. The input voltage must be at least 1V higher than the desired output voltage for proper step-down regulation.; Built-In Digital Voltage Display: An onboard voltage meter allows you to monitor the operating voltage directly without an external multimeter. The tactile button can switch the display between input voltage and output voltage, making adjustment and troubleshooting more convenient.; Voltage Meter Calibration and Display Control: The digital voltmeter has a 040V measurement range with approximately ±0.1V error and supports calibration for improved display accuracy. The voltage display can also be turned off when not needed. Please note that the onboard meter will not function when the input voltage is below 4V.; 3A Max Output with Compact Layout: The module supports up to 3A maximum output current, with 2A recommended for stable normal operation. It features an internal 150kHz oscillation frequency and a compact 66.04 × 35.05mm board size, making it easy to integrate into DIY power boxes, test benches, and small electronic devices.
