ESP32-WROOM-32D WiFi module

The ESP32 is a more advanced successor to the well-known ESP8266. It is a SoC (System on Chip) that can function as a standalone microcontroller and has everything you need on WiFi and Bluetooth 4.0 (BLE 4.0, low-energy) communication. With nearly 30 I / O pins and low power consumption, ESP32 will almost certainly be the leader in the Internet of Things for years to come.

The microcontroller itself works at a frequency of 160MHz (up to 240MHz), while the module has a built-in flash memory of 4MB. It has all the classic protocols like 4x SPI, 2x I2C, 4x UART, and there are many built-in peripherals like 18x 12-bit ADC, 2x 8-bit DAC, 10x capacitive touch GPIO, temperature sensor, SD card controller, Ethernet interface, PWM, etc. The list is really long. It should not be forgotten that this module has FCC certification and PCB trace antenna.
