ESP32 Communication Modules
Industrial-grade wireless communication modules with WiFi/BLE connectivity
Product Overview
Our ESP32 communication modules provide reliable wireless connectivity for industrial IoT applications. Based on ESP32 chipset, these modules support both WiFi (802.11 b/g/n) and Bluetooth 4.2/BLE, enabling seamless data transmission between devices and cloud platforms.
With industrial temperature range (-40°C to +85°C), our modules are designed for harsh environments. They support Modbus RTU/TCP protocol conversion, making them ideal for connecting legacy industrial equipment to IoT networks.
