The ESP-WROOM-32 is a powerful, versatile Wi-Fi + BT + BLE MCU multi-purpose module that can be used for low-power sensor networks and demanding tasks such as voice coding, audio streaming and MP3 decoding, etc. The 2.4GHz Wi-Fi plus Bluetooth dual-mode chip is reliable, scalable and adaptable. Two CPU cores can be individually controlled or powered. Small volume, easy to integrate with other products. ESP32 integrates antenna switches, RF baluns, power amplifiers, low noise amplifiers, filters and power management modules. The complete solution occupies the smallest area of the PCB. The user can cut off the power of the CPU and use the low-power coprocessor to constantly monitor the status of the peripherals or if some of the analog values exceed the threshold. ESP32 integrates also a large amount of peripherals, including capacitive touch sensors, Hall sensors, low noise sensor, SD card interface, Ethernet interface, high-speed SDIO/SPI, UART, I2S and I2C.Product Features: - Onboard CP2102 stable to TTL chip to ensure normal serial port communication. - Support Windows system (cygwin and msys32 simulation environment) and Linux system development - Support LWIP protocol, freertos - Support automatic download, no need to manually switch the download and run mode. - Support ESP32-Arduino - Support three modes: AP, STA, AP + STA coexistence mode - Clock frequency is adjustable from 80MHz to 240MHz. - Lua programming makes your development easier - CPU and memory - The ESP32-D0WDQ6 has two low-power 32-bit LX6 MCUs.
