Basic ESP-WROOM-32 Module With WiFi And Bluetooth - ESP32 NodeMCU - Arduino

The ESP32-WROOM-32 module is based on the ESP32-D0WDQ6 dual-core chip, which is widely used in the IoT. Flash 4MB (32Mbit). UART, I2C, SPI, SDIO, ADC, DAC interfaces. Built-in SMD antenna. Miniature dimensions make it easy to use. The module has a 4 MB (32 Mbit) Flash memory on which you can install any available IoT software. The ESP32-WROOM-32 module has a built-in SMD antenna. Thanks to this, you do not have to worry about connecting an external one. ESP32 is a powerful 32-bit microcontroller. The most important pins of the microcontroller are brought out on the edge of the module. GPIO, I2C, UART, SPI, ADC, PWM, SDIO are available. You can program it in Arduino or with Espresiff SDK.
