Overview

The MX1BM1 Battery Level Monitor Module Gerber Files package provides a compact, low-power battery voltage monitoring PCB design for embedded systems, IoT devices, and battery-powered electronics. This board is designed to safely measure battery voltages ranging from 3.0V to 5.2V, making it suitable for 1S LiPo, Li-ion batteries, and USB-powered systems.

This battery level monitor PCB uses a precision voltage divider circuit combined with a MOSFET-based enable control, allowing developers to measure battery voltage only when required. This approach dramatically reduces standby current and makes the design ideal for deep-sleep applications and low-power battery management systems.

The module outputs a scaled analog voltage that can be directly connected to the ADC pin of popular microcontrollers such as ESP32, ESP8266, ESP32-C6, STM32, Arduino, and Raspberry Pi Pico. The design ensures ADC-safe voltage levels while maintaining measurement accuracy.

If you are searching for battery level indicator PCB Gerber files, battery monitoring circuit design, voltage divider PCB, or battery management design files, this module is a ready-to-manufacture solution.
