Sensors & Modules
The Voltage Detection Module is a compact resistive voltage divider circuit designed to step down high DC input voltages for safe analog pin measurement by 3.3V or 5V microcontrollers. Utilizing a 5:1 reduction ratio (7.5kΩ and 30kΩ resistors), it enables microcontrollers to sample external DC voltages up to 25V safely.
