The Arduino Leonardo is a microcontroller board based on the ATmega32u4 . It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.
The ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Leonardo to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port.

A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection. This stepper motor driver lets you control one bipolar stepper motor at up to 2 A output current per coil. Here are some of the driver’s key features:
This product ships with all surface-mount components—including the A4988 driver IC—installed as shown in the product picture.
This product ships individually packaged with 0.1″ male header pins included soldered in.
The InvenSense MPU-6050 sensor contains a MEMS accelerometer and a MEMS gyro in a single chip. It is very accurate, as it contains 16-bits analog to digital conversion hardware for each channel. Therefor it captures the x, y, and z channel at the same time. The sensor uses the I2C-bus to interface with the Arduino.
The MPU-6050 combines both an accelerometer and a gyro.
2 kind of headers included
The power supply: 3-5 v (internal low voltage difference voltage stabilizing)
Communication: standard IIC communication agreement
Chip built-in 16 bit AD converter, 16 bits of data output
The gyroscope range: + 250 500 1000 2000 ° / s
Acceleration range: ± 2 ± 4 ± 8 ± 16 g
This IMU is not soldered.

This is the Control board that will help you to create your Robotics Project without the hassle of integrating different modules. The DEVIA control board has been used to conceive all the jjRobot projects . We have opted to create a board with enough sensors/ports and outputs but keeping 100% Arduino compatibility. This board contains a powerful ARM M0 processor and will be recognized by the Arduino IDE as the Arduino/Genuino ZERO with NATIVE USB PORT. Just plug and play! Designed in Europe and Assembled by mrobotics in USA.
