ESP-WROOM-32 is a general-purpose Wi-Fi+BT+BLE MCU module, with powerful function and wide application range. It can be used for low-power sensor network and highly demanding tasks, such as audio coding, audio stream and MP3 decoding, etc. Features: This module has ESP32-D0WDQ6 chip, which is extendable and adaptive. Two CPU cores can be individually controlled or powered. Clock frequency adjusting range is 80 MHz to 240 MHz. Users can cut off the CPU power supply, use low-power coprocessor to constantly monitor the state of peripheral or whether some analog is beyond the threshold. ESP32 also integrates rich peripherals, including capacitive touch sensors, hall sensors, low noise sensor amplifier, storage card interface, Ethernet interface, high-speed SDIO/ S P I , UART, I2S, I2C, etc. The board has stable USB to TTL chips, to ensure the normal communication of serial port. It supports automatically download, no need to manual switch between download and run mode. It supports development on for Win (cygwin and msys32 simulation environment) and for Linux system. ESP32-D0WDQ6 has two built-in low-power 32-bit LX6 MCU. Specification: Size: 50*28mm / 2*1.1in Weight: 10g / 0.4oz (approx.) Package list: 1 * ESP32 Module .
