ESP-WROOM-32 ESP-32S ESP32 development board WIFI + Bluetooth IoT smart home ESP-WROOM-32 ESP-32 ESP-32S Compatible with Arduino


The main body of the module is the ESP-WROOM-32 module, and the peripheral adopts the USB serial port chip CH9102 to extend the micro-USB interface. It can be directly debutted through the USB-connected computer, and the data transmission is fast and stable to ensure the normal communication of the serial port.

WIFI + Bluetooth (ESP-WROOM-32) development board
Small size, easy to embed into any product
Powerful, support LWIP protocol, freertos
Support three modes: AP, STA, AP + STA coexistence mode
Lua programming, allowing you to develop more easily
ESP-WROOM-32 is a universal WiFi-BT-BLE MCU module, powerful, versatile.
    This module is the core ESP32 chip, with scalable, adaptive features. Two CPU cores can be individually controlled or powered on. The clock frequency can be adjusted from 80 MHz to 240 MHz. The user can cut off the power to the CPU and use low-power coprocessors to constantly monitor the state of the peripheral for changes or whether certain analog values exceed the threshold. ESP32 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 ESP-WROOM-32 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 5 A, making it suitable for battery-powered wearable electronic devices. The ESP-WROOM-32 supports data rates up to 150 Mbps and delivers up to 22 dBm 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.
    ESP32's operating system is freeRTOS with LWIP, and built-in TLS 1.2 with hardware acceleration. The chip also supports OTA encryption upgrade, developers can continue to upgrade after the release of the production
