Description :
The DFRobot Gravity: Analog Voltage Divider V2 is a high-precision voltage sensing module designed to safely measure DC voltages up to 25V using Arduino, ESP32, ESP8266, Raspberry Pi Pico, STM32, and other microcontroller platforms. Featuring a 5:1 voltage reduction ratio, the module scales higher voltages down to a safe range for analog input pins, preventing damage to sensitive ADC circuits.
Built with the reliable Gravity interface, this module offers easy plug-and-play connectivity and excellent compatibility with a wide range of development boards. It is ideal for battery monitoring, solar energy systems, power supply testing, automotive electronics, IoT devices, and embedded applications where voltage measurement is required.
The module converts a maximum input voltage of 25V into a safe analog output range of 0–5V, allowing accurate voltage readings through standard analog-to-digital converters. Its compact design, high accuracy, and ease of use make it an essential tool for electronics enthusiasts, students, makers, and professional developers.
