This project is a training board based on the ESP32 S3 microcontroller, whose main objective is to provide students with a work environment in which they already have all or almost all of the hardware parts covered and focus their efforts on learning to develop High-quality firmware for this family of microcontrollers.

Demonstration video:

The board can be powered in 3 ways:

• Through the external power header
• Through the USB OTG port
• And through the USB-Serial port.

All these supplies are at 5V DC, and all of them have a reverse voltage protection diode.

The input peripherals are as follows:

• 4 Pushbuttons
• 4 Potentiometers (ADC)

The output peripherals are as follows:

• 4 Simple LEDs
• 4 Addressable RGB LEDs
• 1 Relay
• 1 Buzzer

The dedicated communication ports are as follows:

• 1 UART port
• 1 I2C port
• 1 SPI port
• 1 JTAG port
• 1 USB OTG port

The ports that can be used in the previous connectors are:

• 1 CAN
• 1 I2S

In addition to all the input and output peripherals, the board has a small breadboard to connect any type of sensor or actuator that you wish to add to this board, further expanding the possibilities of projects that can be carried out on this training board. To power the sensors or actuators that are placed on the breadboard, this board has a 6-pin header which provides a voltage supply of 3.3 and 5 volts DC.
