M5Stack PowerHub IoT Development Kit (ESP32-S3)
PowerHub is a programmable controller integrating multi-channel power management. It adopts the ESP32-S3-WROOM-1U-N16R8 core module, equipped with a dual-core Xtensa LX7 processor (240MHz main frequency), supporting 2.4 GHz Wi-Fi, with 16MB onboard Flash and 8MB PSRAM. It features a built-in STM32G031G8U6 coprocessor combined with multiple INA226 voltage and current detection ICs and an electronic switch design, enabling precise management of the power status of multiple expansion interfaces for accurate power consumption control, while providing whole-device low-power wake-up capabilities. The device’s USB Type-C port supports program download and USB OTG functions. An internal USB switch system allows routing the bottom USB interface to the front USB Type-A / USB Type-C ports to facilitate the expansion of USB peripherals. It adopts a high-efficiency power management system supporting multiple power supply modes (DC power + 2S battery + PWR485/PWR CAN input power). It features onboard 2x HY2.0-4P Grove interfaces, RS485, and CAN communication ports, facilitating connection to various sensors and industrial control equipment. It is suitable for industrial automation control, smart home, and other application scenarios, providing developers with a stable and reliable IoT solution.
