Arduino Esplora Development Board

The Esplora differs from all preceding Arduino boards in that it provides a number of the built-in, ready-to-use set of onboard sensors for interaction. It's designed for people who want to get up and running with Arduino without having to learn about the electronics first. The Arduino Esplora is a microcontroller board derived from the Arduino Leonardo.  The Esplora has onboard sound and light outputs, and several input sensors, including a joystick, a slider, a temperature sensor, an accelerometer, a microphone, and a light sensor. It also has the potential to expand its capabilities with two Tinkerkit input and output connectors, and a socket for a color TFT LCD screen.

In the upper left corner of the board, there is a reset pushbutton, that you can use to restart the board. There are four status LEDS: ON (green) indicates whether the board is receiving power supply L (yellow) connected directly to the microcontroller, accessible through pin 13 RX, and TX (yellow) indicates the data being transmitted or received over the USB communication. Like the 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, like a mouse or a keyboard.
