Descritpion

ESP-WROOM-32 is the latest Espressif ESP32 WiFi and Bluetooth module. It has a dual-core 32-bit MCU that integrates WiFi HT40 and Bluetooth / BLE 4.2 technology. ESP32 is equipped with a high-performance Tensilica LX6 dual-core microprocessor. One core supports high speed connection and the other core is used to support user applications.The dual-core MCU has a 240 MHz frequency and 600 DMIPS computational power. The system integrates many peripheral devices, including capacitive touch sensors, Hall sensors, low noise amplifiers, SD card interfaces, Ethernet interfaces, fast SDIO / SPI, UART, I2S and I2C, etc. ESP32 has been designed for mobile devices and Internet of Things (IoT) applications. In addition, ESP32 achieves very low energy consumption. The module has an integrated antenna.
