The ESP32 (ESP-WROOM-32) is a powerful Wi-Fi + BT + BLE MCU module that is versatile and can be used for low power sensor networks and demanding tasks such as voice coding, audio streaming and MP3 Decoding and so on. ESP32 is a safe, reliable, and scalable to a variety of applications. This board is used with 2.4 GHz dual-mode Wi-Fi and Bluetooth chips by TSMC 40nm low power technology,power and RF properties best,which is safe,reliable,and scalable to a variety of applications. The 2.4GHz Wi-Fi plus Bluetooth dual-mode chip is reliable, scalable and adaptive. Two CPU cores can be individually controlled or powered on. Small volume, easy to embed to other products. ESP32 integrates antenna switches, RF balun, power amplifiers, low noise amplifiers, filters and power management modules. The entire solution occupies the least printed circuit board area. Supports the development of Windows systems (cygwin and msys32 simulation environments) and Linux systems. Supporting three modes:AP,STA,and AP+STA, supporting Lua program. Ultra-Low power consumption, works perfectly with the Arduino IDE. ESP32 also integrates a wealth of peripherals, including capacitive touch sensors, Hall sensors, low noise sensor, SD card interface, Ethernet interface, high-speed SDIO / SPI, UART, I2S and I2C.
