～～ What is it? ～～ ・This product is a step-up/down DC-DC converter board (SEPIC type) with manually adjustable output voltage using a flathead screwdriver. ・The board supports connections via USB Type-C, soldering, terminal blocks, and pin headers. ・You can estimate the output voltage from the position of the potentiometer arrow without using a tester. ・To reduce the board size, electronic components are soldered on both sides of the board.
・The output can be turned ON/OFF using the switch on the board.
・The board has four M2 screw holes, allowing it to be securely mounted.

～～ Why did you make it? ～～ I wanted to make smaller type of Step-Up/Step-Down DC-DC Converter Adjustable output voltage by hand.

～～ What makes it special? ～～ ・You can adjust output voltage by hand. ・You can use USB-type-C as Input voltage. ・You can choose input and output terminal as below. pin header, soldering pad, terminal block
