ESP32 WROOM-32D ESP32-DevKitC V4 wifi Bluetooth ESP32 Development Board Module
ESP32-WROOM-32D ESP32-DevKitC V4 wifi ESP32 Development Board Module
If you are interested in connecting your project to the Web and being a part of the IOT (Internet of Things) project, this development board is for you! Like other microcontrollers and microprocessors, the ESP32 is built in power regulation circuits, on-board antennas, noise filters, and fits snugly on any breadboard for rapid prototyping.
The ESP32 can interface with other MCUs as a master or slave, or operate completely independently via SPI / SDIO, I2C and UART. The microcontroller can also support multiple sensors with an SD card and 32 GPIO pins (all available for PWM).
ESP32-WROOM-32D is a powerful, generic Wi-Fi+BT+BLE MCU modules that target a wide variety of applications, ranging from low-power sensor networks to the most demanding tasks, such as voice encoding, music streaming and MP3 decoding.
