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. . 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. 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. material: plastic Color: as shown Package Contents: 2PCS ESP32 Development Board Only the above package content, other products are not included. 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.
