The Arduino IDE is used to program and debug your Arduino-compatible boards. JeeLabs has a variety of Arduino-like boards. I use the following settings in the Arduino IDE:

On Mac OS X, the Serial port (Tools/Serial Port) should be set to a device named /dev/tty.usbserial-XXXXXXXX. The speed should be set at 57600 bps.

JeeLabs device Arduino IDE: Tools/Board
JeeLink v3 Arduino Uno
JeeNode v6 Arduino Duemilanove or Nano w/ ATmega328

TIP: If you have more than one board, multiple serial port devices will exist. You can easily find out the right one by checking the available entries first (in Tools/Serial Port), then plugging in the board, then checking again.
