Devia Robotics Control board v1.0
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 has a powerful ARM M0 processor and will be recognized by the Arduino IDE as the Arduino ZERO with NATIVE USB PORT. Just plug and play! Designed in Europe and Assembled in Europe :-)
Features:
- ARM Cortex M0 processor (ATSAMD21G18) (the same mounted on the powerful Arduino Zero)
- ESP12 Wi-Fi module integrated (programmable via GPIO pads on the back of the board)
- MPU ICM 20600 6 axis (High Performance 3-axis gyroscope, 3-axis accelerometer module)
- AUX OUTPUT: Controllable Voltage regulator (up to 12V, 1A)
- Vin Power Jack (the board accepts from 9 to 15V DC)
- 3x stepper motors outputs
- 4x servo outputs (up to 1.5A)
- Customizable button “A” (can be used to change the behaviour of the robot, pause it, change internal parameters…)
- Reset button
- i2C port
- SPI port (perfect to control RGB LED strips)
- UART port
- SENSOR port (Analog, Digital, Ground and +3.3V)
- GPIO on the back of the board
- Micro USB Port
- Arduino UNO footprint
- 100% Arduino ZERO compatibility. Just connect the board to the computer, and the Arduino IDE will recognize it as the Arduino ZERO board -Native USB port-
* All the headers already soldered


NEMA 17 Stepper motor (PACK OF 2/3) + CUSTOM CABLES
This is the NEMA17 stepper motor used in every jjRobots Project. You liked the motors which came with your kit and want another pack of two? Did you like its sturdiness / easy plug-in connector (forget to solder every time you have to change the cable length) ? This is the perfect stepper motor for MAKERs and Robots enthusiasts.
- This NEMA17 stepper motor deliver up to +32% torque compared to same size regular NEMA17 motors (for the same current demand)
- With less than 5% step accuracy deviation.

CREATE YOUR OWN ROBOTICS KIT GETTING WHAT YOU NEED
NOTE: the 3D-printed parts are not included. You can get the STL files from Thingiverse and print them by yourself. The links are available in the respective robot assembly guides too. From the list below: select the correct power supply for the KIT and some optional items you may want to add to your KIT.
You already have NEMA17 motors?: No need to add them. Planning to use a longer rail for the camera slider? Save the cost of getting one from us.


The Sphere-O-bot painting robot
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 robot is based on the original design of Evil Mad Scientist
Features:
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. This design also features the regular JJrobots electronics (the same we have used in all our robots). So you can create this robot or any other just simply printing new 3D printed parts and uploading the appropriate code.
The original idea belongs to Evil Mad Scientist
The frame was designed by Attila Nagy
The Sphere-O-bot is adjustable, and is designed to draw on all kinds of things that are normally “impossible” to print on. Not just eggs but ping pong balls, Christmas ornaments, light bulbs, and (yes) eggs (duck, goose, hens…).
The Sphere-O-bot frame was designed by Attila Nagy and slightly modified by JJrobots. The pen and egg motors are high-torque precision stepping motors, and the pen lift mechanism is a quiet and reliable servo (SG90) motor.
