Product Name: Digital Voltage Meter
Supply Voltage: DC 3.5–30V
Measurement Range: DC 0–30V
Operating Current: <20mA
Refresh Rate: 5Hz (switchable to 10Hz by shorting Pin B)
Measurement Accuracy: Approx. 0.7% (e.g., for a 10V input, display error is 10 × 0.007 = 0.07V)
Display Digits: Three-digit white text (automatic decimal point shifting)
Display: 0.5-inch OLED display
Resolution: 88 × 48
Applications: Industrial control equipment, adjustable power supply output voltage display, sensor supply voltage detection, vehicle battery voltage monitoring, and other embedded applications
Jumper A: By default, displays the voltage symbol (V); when jumpered, the (V) symbol will not be displayed
Jumper B: Default refresh rate is 5Hz; jumpering B switches to 10Hz
