Leveraging the design prowess of Freeburn Robotics Limited (PiBorg), we commissioned a board that combines advanced motor control, input, and power on a single core board. Plus, it looks EPIC.

Robot Core uses I²C (Inter-Integrated Circuit). I²C is a serial computer bus invented by Philips Semiconductor. I²C is a very easy to use two-wire bus that your Pi will have no problem talking to. A built-in level shifter ensures compatibility to both 3.3 volt and 5 volt I²C buses.

It is compatible with all current and past generations of Raspberry Pis and with many Arduinos. (The Raspberry Pi Zero will need 6 pin headers soldered to it).

The Robot Core board comes with a ton of software and example programs to get you up and running on both the Raspberry Pi and the Arduino.

Power:

  • Main power input – 6.4V to 14V DC
  • On-board DC-DC regulator for generating 5 volts. Capable of handling 6 Amps total load (this also allows it to power the Raspberry Pi).
  • Optional separate supply input for servos (approx 5-7.2 volts)
  • Separate power input for Dynamixel servos

Motor drive:

  • Up to two 5 Amp continuous load DC motor outputs
  • Can be used as a pair to drive a single stepper motor
  • Built-in safety protection from motor faults and overheating
  • Optional connector for a normally-closed EPO (emergency power off) switch

Servos:

  • 16 bit PWM driver provides accurate positional output
  • Supports both analog and digital servos
  • Tuning GUI (graphical user interface) allows each servo to be set for the correct operational range
  • Start-up positions can also be set for each servo
  • Up to 8 conventional servo outputs

Dynamixel servos:

  • Two ports are provided for connecting Dynamixel servos
  • Support for multiple Dynamixels connected at the same time
  • Simple positional control functions make basic moves easy
  • All functionality of the Dynamixel is accessible via low-level commands

Ultrasonics:

  • Up to 4 HC-SR04 ultrasonic modules supported
  • Filtered readings can be used for better accuracy, unfiltered readings can be used for faster readings
  • Readings are converted into millimeters by the provided library

Analog:

  • Up to 8 12-bit analog inputs for sensors or feedback
  • Range of 0V to 5V for each input
  • Protection from exceeding the input limits
  • Additional analog reading for the main power voltage
  • Configurable warnings for low power

Software:

  • Easy to use Python library for all of the board functionality
  • Examples provided for each functional part of the board
  • GUIs provided for most functions on the board

What Else?:

  • Boards can be daisy-chained to connect more than one
  • Each board uses I²C to talk with the Raspberry Pi + I²C addresses, can be changed if desired
  • Clear on-board labelling
  • Functional sections have their own box
  • Each port and screw terminal has its pins labelled
  • Prototyping space for adding more functionality
  • Easy to access voltage rails
  • Access to the Raspberry Pi I²C at 5V levels
  • Prototyping space removable to make the board smaller
  • Status LED’s for: Main power voltage, DC motor status, Script controllable status + 5V and 3.3V power
