This project aims to control up to 4 relays remotely either using WIFI or Bluetooth. The SOC ESP32 S3 is used as the main core of the project, it provides wifi and Bluetooth to the project, as well as great processing power thanks to the two cores it has.

This project can be powered with a 5-volt DC both through the USB connector as well as through the external power connector. The relays also work at 5 volts DC, which means no extra power supply is required to run them.

Each relay has an LED to indicate if the relay is activated or deactivated. The board also has an RGB LED which is controlled with a single GPIO of the microcontroller because this RGB is directional.

As inputs, there are 4 user buttons, which can be used to control the flow of the program. It also has a 16-pin header which has 16 GPIOs for external use, among which there are I2C, SPI, UART, USB, and ADC connections, among other peripherals.

There is also a 6-pin header with 5V, 3.3V, and GND outputs for external use.
