ITEM NAME:ESP32-WROVER Dual Core Wifi Bluetooth Wireless Module 2.4GHz Audio Transceiver Features: It is universal Wi-Fi BT BLE MCU module that is powerful and versatile, and can be used in low-power sensor networks and extremely demanding tasks such as voice coding and audio streaming. And MP3 decoding and so on. 4MB SPI flash and 1.8V, 64 Mbit SPI PSRAM. ESP32-D0WDQ6 chip is adopted, which is scalable and adaptive. Two CPU cores can be controlled separately. The clock frequency can be adjusted from 80 MHz to 240 MHz. The user can turn off the power to the CPU and use the low-power coprocessor to monitor changes in the state of the peripheral or whether certain analogs exceed the threshold. The ESP32 also integrates a wide range of peripherals including capacitive touch sensors, Hall sensors, low noise sense amplifiers, card interfaces, Ethernet interfaces, high speed SPI, UART, I2S and I2C. Specifications: Model: ESP32-WROVER Material: PCB Color: black Size: (Approx) 18.0x25.5x3.1mm&;nbsp; Package Included: 1 PC x Module Note: 1. Due to the light and screen difference, the item's color may be slightly different from the pictures. 2.
