WiFi Bluetooth Module ESP32-WROOM-32D DevKitC
PRODUCT ID: ESP-BOA-003
ESP32-WROOM-32D is a powerful Wi-Fi+ Bluetooth + Bluetooth Low Energy MCU. It is small in size and supports LWIP protocol, FreeRTOS and works in 3 modes: AP, STA, AP + STA. The core of this module is the ESP32-WROOM-32D chip with two CPU cores that can be individually controlled or powered on. The clock frequency can be adjusted from 80MHz to 240MHz. The ESP32-WROOM-32D also integrates a wealth of peripherals, including capacitive touch sensors, hall sensors, low-noise sense amplifiers, SD card interface, ethernet interface, high-speed SDIO / SPI, UART, I2S and I2C.
The ESP32-WROOM-32D integrates traditional Bluetooth, Bluetooth Low Energy and Wi-Fi for a wide range of uses: 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 their phones or broadcast BLE Beacon for signal detection. The ESP32 chip sleep current is less than 5uA, making it suitable for battery-powered wearable electronic devices. It supports data rates up to 150Mbps and delivers up to 22dBm output power through a power amplifier for maximum range wireless communication. As a result, the chip has industry-leading specifications and offers the highest performance in terms of high levels of integration, wireless transmission distance, power consumption and network connectivity.
