Stepper motor DRIVER (A4988) + heatsink

$3.87

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:

Simple step and direction control interface
Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step
Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates
Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection
Short-to-ground and shorted-load protection
Heat sink included

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.

B-robot 3 Axis Gyroscope + Accelerometer Module

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.

Details:

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.

Arduino LEONARDO (clone) + USB cable

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.

Details:

Microcontroller	ATmega32u4
Operating Voltage	5V
Input Voltage (recommended)	7-12V
Input Voltage (limits)	6-20V
Digital I/O Pins	20
PWM Channels	7
Analog Input Channels	12
DC Current per I/O Pin	40 mA
DC Current for 3.3V Pin	50 mA
Flash Memory	32 KB (ATmega32u4) of which 4 KB used by bootloader
SRAM	2.5 KB (ATmega32u4)
EEPROM	1 KB (ATmega32u4)
Clock Speed	16 MHz
Length	68.6 mm
Width	53.3 mm
Weight	20g

jjRobots electronic brain shield v3.1 (Devia)

JJrobots´s Brain SHIELD. Created to simplify the set up and integration of all the different devices involved in the jjrobots projects.

This SHIELD has:

TWO stepper motor OUTPUTs
TWO SERVO OUTPUTs
I2C communications
Push button (customisable)
SENSOR port (SONAR, IR…)
ESP12-E (ESP8266) WIFI module (you can communicate to this SHIELD from any smartphone/tablet/PC using it)

Some OPEN robots you can create with this Brain Shield:

B-ROBOT EVO 2 is a remotely controlled self-balancing arduino robot created with 3D printed parts. With only two wheels, B-ROBOT is able to maintain his balance all the time by using his internal sensors and driving the motors. You can control your Robot, making him moving or spinning, by sending command through a Smartphone, Tablet or PC while he keeps the balance.
The fastest self balancing robot (remotely controlled using your smartphone). Take a look to its skills!

The iBoardbot is an internet controlled robot capable of writing+drawing (and wiping!) on a glass surface.

Remotely controlled Torch/ Laser robot: Laser pointer is a remotely controlled Arduino robot created with 3D printed parts. With only two servos, this robot is able to point any object in the X and Y axis.

Sphere-O-Bot: The Sphere-O-bot is a friendly art robot that can draw on spherical or egg-shaped objects from the size of a ping pong ball to a large duck egg (4-9 cm).

Many more to come!
