## Description

## Overview

The M5Stack Station-Bat is an industrial-grade programmable embedded controller built around the ESP32-D0WDQ6-V3 dual-core processor. Designed for field deployment, it features a rugged enclosure with a 1.14-inch IPS display (240x135), three programmable buttons, and six Grove (HY2.0-4P) expansion ports for connecting sensors and actuators.

Key features include an INA3221 triple-channel current/voltage monitor for power management, an MPU6886 6-axis IMU for motion sensing, a BM8563 RTC for timekeeping, and 7 SK6812 addressable RGB LEDs. The Station-Bat model includes dual 18650 battery holders for extended off-grid operation and a USB-A port for powering external devices.
