How to use an Arduino Uno as a serial adapter for an OLPC XO laptop.

  • disconnect all wires from the Arduino Uno,
  • connect the USB cable to a system (the host) running the Arduino development environment,
  • download passthrough-serial-adapter.ino and program it into the Arduino Uno,
  • on the host, start a serial terminal application like screen, and verify that pressing keys causes the D13 LED to flash,
  • connect a GND pin on the Arduino to the GND pin on the serial connector of the XO (the target),
  • connect the D0 (RX) pin on the Arduino to the RX pin on the target; this carries keys from the host to the target,
  • connect the D1 (TX) pin on the Arduino to the TX pin on the target; this carries text from the target to the host,
  • turn on the target, and the boot text should be displayed.
