Gravity: Analog Voltage Divider V2

The Gravity: Analog Voltage Divider V2 is a compact voltage detection module designed to measure DC voltages from 0.0245V up to 25V. It uses an internal resistor divider to step down input voltages by a factor of five, allowing standard microcontroller analog inputs to safely read higher voltage lines. This sensor is well suited to students, makers, and hobbyists building battery monitoring and power management projects.

Five-to-one voltage reduction

Based on a resistor divider circuit, the module reduces incoming DC voltage fivefold. This allows 5V microcontroller analog pins to safely monitor external power sources up to 25V without exceeding input thresholds.

Updated Gravity pin mapping

This revision incorporates updated analog sensor port pin mapping and operates across a wide 3.3V to 5V voltage range. The layout features clear analog port labelling and functional icons for straightforward, error-free wiring.

Immersion gold construction

The board features an immersion gold surface finish alongside a high-quality connector for reliable electrical connectivity. These durable hardware enhancements ensure consistent signal transmission during long-term prototyping.

Compact mounting layout

Measuring 22 x 30mm, the module includes standard assembly features with two 3mm mounting holes spaced at multiples of 5cm intervals. This compact footprint easily integrates into robotics chassis, enclosures, and sensor brackets.
