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.

B-robot 3 Axis Gyroscope + Accelerometer Module http://www.jjrobots.com/product/b-robot-3-axis-gyroscope-accelerometer-module/ http://www.jjrobots.com/product/b-robot-3-axis-gyroscope-accelerometer-module/#respond Tue, 03 Feb 2015 14:48:47 +0000 http://www.jjrobots.com/?post_type=product&p=1169 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. GY-521 Details: 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 RoHS]]> http://www.jjrobots.com/product/b-robot-3-axis-gyroscope-accelerometer-module/feed/ 0 B-Robot EVO KIT (Plug and Play Robot version) http://www.jjrobots.com/product/b-robot-kit-plug-and-play-robot-version/ http://www.jjrobots.com/product/b-robot-kit-plug-and-play-robot-version/#comments Wed, 12 Aug 2015 12:14:14 +0000 http://www.jjrobots.com/product/b-robot-kit-plug-and-play-robot-version/ JJrobots´s B-ROBOT EVO 2 Kit.

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 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.
1
  • The iBoardbot is an internet controlled robot capable of writing+drawing (and wiping!) on a glass surface.2
  • 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.
3
  • 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).
The Sphere-O-Bot is a simple 2 axis drawing machine that can draw on most spherical surfaces. You can use it to decorate balls or eggs.
  • Many more to come!
