Description <br> ESP-WROOM-32 is a general-purpose WI-FI+BT+BLE MCU module with powerful functions and a wide range of uses. It can be used in low-power sensor networks and demanding tasks, such as speech encoding, audio streaming, and MP3 decoding. . <br> The core of this module is the ESP32-DOWDQ6 chip, which is scalable and adaptive. The two CPU cores can be controlled or powered independently. The clock frequency can be adjusted from 80MHZ to 240MHZ. <br> Users can cut off the power supply of the CPU and use a low-power coprocessor to continuously monitor the status changes of peripherals or whether certain analog quantities exceed thresholds. ESP32 also integrates a wealth of peripherals, including capacitive touch sensors, Hall sensors, low-noise sensor amplifiers, SD card interfaces, Ethernet interfaces, high-speed SDIO/SPI, UART, I2S and I2C, etc. <br> <br> material: plastic <br> Color: as shown <br> <br> Package Contents: <br> 1PCS ESP32 Development Board <br> <br> Only the above package content, other products are not included. <br> Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm. <br>
