Portable voltmeter

• Structural shellIt adopts a split 3D-printed shell, which is divided into a base and a back cover. The back cover is imprinted with the "Moring" logo, and screw holes are reserved at the four corners for locking and fixing. The shell is provided with display screen openings and wiring holes. The internal space is well-organized, perfectly accommodating the digital voltage gauge, and it is easy to disassemble and assemble. It also features a delicate print layer texture.

  

  

   

• Functional principleIt is equipped with a 0.36-inch two-wire DC digital voltmeter head, which can display the voltage of DC power sources such as lithium batteries in real time. The screen numbers are clear and bright, and it has built-in reverse connection protection. The wiring is simple, and it can be used with an 18650 battery to complete power supply detection and intuitively check the remaining battery power.

   

• Use scenariosIt is compact and portable, suitable for maker DIY, electronic training, battery maintenance, and small circuit debugging. It can be used as a portable voltage detection tool, and it can also be used for science and technology projects and as a desktop electronic display decoration.
