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.
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

NOTE: There are FULL ROBOT KITS ready to be sent to you in the SHOP (scroll down to the very end of this page to see them too)
JJrobots´s B-ROBOT EVO 2 Kit. Created to simplify the set up and integration of all the different devices involved in this project.
This COMPLETE VERSION includes all the electronic and hardware components required to create the B-Robot. You just need to assemble everything (optional 3D parts)
What you get when you buy this KIT:
Create very different OPEN SOURCE robots using the same electronics and ancillary elements. Everything can be modified, Hacked and customised!
STEM education robotic KIT: In addition to being fun, the MOST AWESOME ROBOTIC STEM KIT engage beginners and advanced students and incorporate many of the fundamental STEM concepts providing a learning platform that everyone enjoys
Fight battles with your remotely controlled B-robot, play with your torch from 50 meters away, send messages to your friend using the Iboardbot!, paint balls/eggs using your own pens or…create your new awesome robot from scratch!
Do you think you can improve or hack any of these robots? Do it! They are OPEN SOURCE robots, so all the info,know how and code is available for everyone. Share the knowledge! (and take a look at the JJrobots FORUM)
This is the motor used in every jjRobot. You liked the motors that came with your kit and want another pack of two? Do you like its sturdiness and its connector (forget to solder every time you have to change the cable length) ? This is the perfect stepper motor for MAKERs and Robots enthusiasts.
Select the cable you want with each motor for free!
