USB Buck-Boost converter modules that adapt the voltage from 3.5V-12V to 1.2V-24V, operate as both Step-Up and Step-Down power supplies, and can supply voltages up to 5V, 3.3V, 9V, 12v

Precise Calibration: This power supply module has a voltage display, and is an adjustable USB power supply module that converts 3.5-12V to 1-24V. 2. Output: By connecting USB or Micro USB, it can easily provide adjustable voltage in the range of 1V to 24V with a power output of 3W. 3. Adjustable voltage: It uses a precision potentiometer with multiple turns to adjust the voltage. 4. Data storage: It automatically saves the state before power failure, ensuring that the output data remains intact.
One button can turn off the output and save the current state before powering down, so there is no data loss.
