An open source PCB to control simple robots

The board integrates the control electronics required to operate a robot. Sensors and actuators can be connected directly.

• Dimensions:

  • 104 mm x 80 mm

• Power supply:

  • The board is supplied with a 7.5V voltage (battery or LiPo).

• Sensor connections:

  • 4 ports for connecting sensors, each with a 5V power supply as well as 4 additional signal lines that can be used either as analog input (2x), digital IO (4x), UART or I2C interface. Alternatively, RJ-12 or 6-pin PCB header connector can be soldered in as a plug connection.
  • 2 ports for connecting a push button (binary input)

• Actuator connections:

  • 4 ports for connecting DC motors, each with a power output (H-bridge) as well as a power supply and digital input for an encoder.
  • 2 ports for connecting servo actuators

• Bus connections:

  • 1 port as I2C bus connection with power supply (5V)
  • 1 port as SPI bus connection with power supply (5V)

• Communication:

  • Bluetooth module
  • USB micro

• Software download:

  • USB boot loader
  • Debug interface

• User interface:

  • 2 push buttons
  • 3 LEDs
  • 1 reset button
  • 1 main switch
