It is a Leonardo board, the Esplora uses an Atmega32U4 AVR microcontroller with a 16 MHz crystal oscillator and a micro USB connection capable of acting as a USB client device, such as a mouse or keyboard. In the upper left corner of the module, there is a reset button, which you can use to restart the module.
There are four status LEDs:
- ON [green] indicates whether the module is receiving power
- L [yellow] connected directly to the microcontroller, accessible via pin 13
- RX and TX [yellow] indicates the data that is transmitted or received through the USB communication
- The module contains everything necessary to support the microcontroller; simply connect it to a computer with a USB cable to start. Esplora has built-in USB communication; It may look like a computer connecting to a mouse or keyboard, as well as a serial (CDC) / virtual COM port.
