Expansion Connector Wiring Diagram
Note: The 25 mA current source is a true current source. Maximum compliance voltage is approximately
V+, the input voltage to the temperature controller. No external current limit resistors are needed for the
LED. The LED must be capable of being driven with a 25 mA continuous current.
