The anode rail is the high voltage output for the ArduiNIX shield. It supplies driving voltage to the anode pins of your tubes. Make sure to use a resistor between the anode terminals and the tubes of your choice. Each anode terminal is designed to handle up to two anode connections, meaning the four anode terminals will support up to eight nixie tubes total.
