Upgrade OpenSprints Hub with an Arudino Uno Rev3

The OpenSprints project has been around for a over a decade, and in that time Arduino (which is the brains of the project) has made some significant improvements in driver support. If you purchased a second hand OpenSprints system, or you purchased our system before December 2014 we insist that you upgrade your Arduino. Beware of clones, we recommend buying from the source.


  1. Take apart the OpenSprints Hub case by unscrewing the four screws on the bottom. BOTTOM: Case Screw are on the bottom.
  2. Unscrew the four screws that attach the PCB to the bottom of the case. TOP: Unscrew interface board from bottom of the case.
  3. Remove the two red end panels.
  4. TOP: Unscrew the three screws that hold down the Arduino
  5. TOP: Lift straight up to remove the Arduino.
  6. TOP: From the bottom, remove the standoff that is next to the LED and resistor.
  7. Insert the Arduino Uno Rev3 and follow the instructions in reverse to reassemble.
