Espressif Systems Dual-Core Wi-Fi Dual-Mode Bluetooth Modules

Espressif Systems Dual-Core Wi-Fi® Dual-Mode BLUETOOTH®/BLE (BLUETOOTH® Low Energy) Modules are compact, high-performance, low-power devices designed to provide a complete wireless solution tailored to advanced IoT applications. These Modules are powered by the Espressif Systems ESP32 System-on-Chip (SoC) and feature a wide range of peripherals, software stacks, flash memory, and an integrated antenna. Two independently-controlled CPU cores offer adjustable clock frequencies ranging from 80MHz to 240MHz. The modules are fully pre-certified, allowing faster time to market with reduced development costs. The small size allows easy integration into space-constrained devices.
