DFRobot ESP-WROOM-32 ESP8266 WiFi-BT-BLE MCU Module

DFRobot ESP-WROOM-32 ESP8266 WiFi-BT-BLE MCU Module has a dual-core 32-bit MCU, which integrates WiFi HT40 and BLUETOOTH®/BLE 4.2 technology inside. Compared to the Arduino ESP8266 (the previous generation), the ESP32 has a significant performance improvement. The module is equipped with a high-performance dual-core Tensilica LX6 MCU. One core handles high-speed connection and the other for standalone application development. The dual-core MCU has a 240MHz frequency and a computing power of 600DMIPS.
