PowerHub is a programmable controller integrating multi-channel power management. It adopts the ESP32-S3-WROOM-1U-N16R8 main control module equipped with a dual-core Xtensa LX7 processor (up to 240MHz), supporting 2.4 GHz Wi-Fi, with 16MB Flash and 8MB PSRAM onboard. A built-in STM32G031G8U6 coprocessor, combined with multiple INA226 voltage/current detection ICs and electronic switch design, enables precise management of power states for multiple expansion interfaces, achieving accurate power consumption control and providing low-power wake-up functionality for the whole device. The USB Type-C port can be used for program download and USB OTG functions. Inside, a USB interface switch allows the bottom USB port to be switched to the front USB Type-A or USB Type-C interface for convenient expansion of USB peripherals. The device features an efficient power management system, supporting multiple power supply modes (DC power + 2S battery power + PWR485/PWR CAN input power). It is equipped with 2x HY2.0-4P Grove ports, RS485, and CAN communication interfaces, facilitating connections to various sensors and industrial control devices. Suitable for industrial automation control, smart home, and other scenarios, it provides developers with stable and reliable IoT solutions.
