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.
Table 2. Power Configurations for the EVAL-ADUCM420QSP1Z (WLCSP)
EVAL-ADUCM420QSP1Z Optional Jumper Information Jumper Configuration
P20 Yes Power selection either via
USB power or via Arduino
power 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.
JP16 Yes Power from Arduino via the
EVAL-ADUCM420QSP1Z
board If this jumper is shorted, the EVAL-ADUCM420QSP1Z also powers
up the Arduino.
JP11 1 Yes 3.3 V LDO output Short.
JP12 1 Yes 3.3 V power to Arduino
IOREF pin Short.
JP13 1 Yes ADuCM420 reset to Arduino
reset Short.
JP14 1 Yes 3.3 V power to Arduino Short.
JP15 1 Yes 5 V power to Arduino Short.
1 The JP11 to JP15 connectors are used if the Arduino is powered up via the EVAL-ADUCM420QSP1Z board.
