ESP32-S3 IoT PLC Ethernet

Erqos EQSP32CE is a DIN rail-mountable industrial IoT PLC based on an ESP32-S3 WiFi and Bluetooth SoC and offering Ethernet, RS-485, RS-232, and CAN bus industrial communication interfaces. The IIoT logic controller also features several protected digital (16x) and analog (8x) inputs, eight current inputs, eight “special mode” analog inputs, and sixteen digital outputs with PWM support. A USB-C port is used for firmware flashing and monitoring, and the PLC takes a wide 7V – 26V DC input voltage and outputs 5V/1A for I/O expansion modules. Erqos EQSP32CE specifications: SoC – Espressif ESP32-S3 dual-core LX7 processor @ 240 MHz with 8MB Flash, 512kB RAM, wireless connectivity (so probably ESP32-S3FN8) Communication interfaces 10/100 Mbps Ethernet RJ45 port Wi-Fi + Bluetooth Low Energy (on ESP32-S3) with internal antenna RS232 (protected) and RS485 half-duplex (protected) with support for Modbus RTU, DMX512, and custom serial protocols CAN Bus (protected) USB – 1x USB-C power for […]
