Congratulations to Antti Seppänen, whose Beagle Board-based robot is the winner of the first Beagle Board design contest.

What’s more, Antti also created a very cool expansion board for the Beagle Board, and made the design available under a CC license:

My Beagle bot required building an expansion board. Some requirements for expansion board:

  • Wide input voltage range up to at least +15 volts
  • +5 volts stable and reliable power supply for Beagle Board and for USB hub
  • Level shifters and pin headers for +5 volt tolerant I2C, SPI and some GPIOs
  • 5 pcs of 50 Hz PWM output for normal RC servos
  • RS232 header, preferably two
  • Open-drain outputs for various peripherals
  • Control of servos and open-drain outputs from Beagle via I2C

The expansion board is going to be a big help for Beagle Board hackers, as it solves a lot of issues (power, level shifting, etc)!
