EVAL-ADUCM420QSP1Z

HARDWARE MODULE

ADUCM420 AND ARDUINO POWER

Customers may want to connect their own custom circuits to
the EVAL-ADUCM420QSP1Z evaluation board.
Five connectors of the EVAL-ADUCM420QSP1Z evaluation
board support an Arduino® Uno or Arduino Zero connection

interface to external PCBs. The EVAL-ADUCM420QSP1Z
evaluation board can power the external Arduino-based board.
Inversely, the Arduino is also capable of powering up the whole
module, including the ADuCM420. Table 2 shows the jumper
connections for the power configurations of the EVAL-
ADUCM420QSP1Z and the Arduino.
Jumper Configuration
Pin 1 and Pin 2 = USB powered. Pin 2 and Pin 3 = Arduino powered.
Do not use USB power for the EVAL-ADUCM420QSP1Z board if the
Arduino and the evaluation board are powered up together.
If this jumper is shorted, the EVAL-ADUCM420QSP1Z also powers
up the Arduino.
