Get the new DEVIA control board instead the Brain shield + Arduino Leonardo: 100% compatible and much more powerful


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 
  • 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)


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 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).

NOTE: There are FULL ROBOT KITS ready to be sent to you in the SHOP . Save the hassle of getting all the components from different sources and support jjRobots getting a KIT!

jjRobots projects features:

  • Open projects: code and 3D design files are open and shared. You could personalise your robots as much as you want.
  • DIY & Hackeable: the robots are not closed final products, all are open, modifiable and hackeable platforms, perfect to learn and play as much as you want!
  • Develop your own apps: You could modify the source code of jjROBOT to perform new tasks but the communication protocol is also open so you can develop your own IOS, Android, PC remote apps to control your customised robot!
  • Learn: All JJROBOTS products are OPEN SOURCE. You will receive a well documented project (source code and external documentation). We want you know all that is happening inside your Robot! This is ideal for learning and teaching technology.  All this KNOW HOW is available for everyone: How we are controlling the motors, how we read and integrate the information from gyros and accelerometers, how we are controlling the stability of the robots, how we communicate with the control apps, etc…
  • We are strongly committed to create our robots always using the same elements and electronics. This Brain Shield will be the CORE inside any robot. So, if you get it, you will use this Brain to create ANY jjRobot

– Build with your kids, at school, for yourself… these robots are unique gadgets.

– All the jjRobots have a medium size

– There is a small community behind the jjRobots so you will have a forum to ask questions, share your experiences and contact other users…

    Very handy Arduino Shield. My students have been using it two months (actually we had to buy several) to create different robots. The B-robot behavior is quite surprising.
    Thank you for this Shield!

    Very handy WIFI Arduino Shield. The possibility of sending commands from any smartphone/Tablet and control two servos and two stepper motors has been very useful so far

    Everything you need if you have your own 3d printer and motors. Thank you for the support

    Combine this board with a 3d printer for endless possibilitiesBoard seems to be high quality and has everything you need to create your very own robot. Combined with parts from 3d printers there are endless possibilities.

    B-RobotThe Brain Shield card is perfect, the arduino source code is well designed. I just have one thing to say, the 3d parts available on the Github are not the last existing version. I printed parts unnecessarily. I find the lastest version of 3d parts on thingiverse diectly.
