Voltmeter DIY Kit - VOT - 8

The VOT-8 Voltmeter DIY Kit offers an engaging way to learn about electronics while building a fully functional voltmeter. Ideal for students, hobbyists, and DIY enthusiasts, this kit is perfect for measuring DC voltages in various projects, with two modes for added flexibility.

Parameters

Kit Name: Voltmeter DIY Kit

Model: VOT-8

Operating Voltage: DC 3.5~25V

PCB Dimensions: 33mm x 52mm

Measurement Range: DC 0~30V

Measurement Accuracy: 0.1V

A push-button switch controls the VOT-8 Voltmeter Kit and can operate in either a two-wire or three-wire configuration. (The wiring is configured for two-wire mode upon delivery.)

Assembly Steps

1. Solder the 10 resistors (3 on the front, and 7 on the back inside the red frame).
2. Solder the capacitors, diodes, and potentiometer.
3. Solder the push-button switch (make sure to orient it correctly).
4. Install the IC socket from the back of the board and solder it from the front.
   • Trim any excess pins from the IC socket to prevent interference with the LED display.
5. Install the LED display.
6. Install the microcontroller and copper standoffs (pay attention to the microcontroller’s orientation).

This kit offers an excellent opportunity to learn about voltage measurement circuits and build a practical voltmeter.
