OUTLINE The Flow Connect is a highly integrated industrial controller designed for complex automation and communication environments. It features the ESP32-S3R8 microcontroller at its core, equipped with a dual-core Xtensa LX7 processor running at up to 240MHz, and includes 8MB PSRAM and 16MB FLASH memory, capable of handling high-performance computing and multitasking demands. For storage, it utilizes 128Mbit (16MB) 3.3V NOR flash, ensuring long- term, stable operation for firmware, data, and configuration file storage. The controller supports multiple communication protocols, including dual CAN bus, RS232, RS485, and TTL interfaces, making it suitable for a wide range of industrial and IoT applications. To enhance user interaction, the Flow Connect integrates Neopixel RGB LED lighting control, enabling dynamic color and lighting effects for intuitive visual feedback. In addition, the Flow Connect power management system employs multiple DC-DC converters that support various voltage outputs from 12V to 3.3V. It also features built- in electronic fuses (eFuse) to protect each voltage channel from overcurrent, ensuring safe operation even in harsh environments. The Flow Connect is designed with the demanding requirements of industrial control, intelligent transportation, and IoT gateway applications in mind, offering reliable multi- protocol communication, robust data storage, dynamic RGB display, and comprehensive power protection. 1.1.
