ESP-WROOM-32 is a powerful and versatile WiFi BT BLE MCU module.
ESP32 core module, with scalable adaptive features, the two CPU cores can be controlled or powered individually. The clock frequency can be adjusted from 80 MHz to 240 MHz. The user can cut off the CPU power and use low co-processing power. ESP32 also integrates a large number of peripherals, including capacitive touch sensors, hall sensors, low noise amplifiers, SD card interface, Ethernet interface, high speed SDIO/SPI, UART, I2S and I2C.
ESP-WROOM-32 integrates traditional Bluetooth, low-energy Bluetooth and Wi-Fi and has a wide range of applications: Wi-Fi supports a wide range of communication connections, as well as direct connection to the Internet via a router; Bluetooth allows users to connect mobile phones or broadcast BLE messages. The standard for signal detection, the sleep current of the ESP32 chip is less than 5 mA, suitable for battery-powered portable electronic devices. The ESP-WROOM-32 supports data rates up to 150Mbps, and provides up to 22dBm output power through a power amplifier for the greatest range of wireless communications. Accordingly, the chip has industry-leading specifications and provides the highest performance in terms of high integration, wireless transmission, power consumption and network connectivity.
The ESP32 operating system is a freeRTOS with LWIP and built-in TLS 1.2 with hardware acceleration. The chip also supports OTA encryption upgrade, and developers can continue to update after product release.
