EVALUATION BOARD HARDWARE
HARDWARE SETUP
The EV-TEMPSENSE-ARDZ development kit contains the
following boards (see Figure 2 to Figure 4
)
:

The EVAL-ADT7420ARDZ shield

The EVAL-ADT7420MBZ remote evaluation board

The EVAL-ADT7320MBZ remote evaluation board
Place the EVAL-ADT7420ARDZ shield on top of the Arduino™
development board by matching up the EVAL-ADT7420ARDZ
shield power with the P4, P5, P6, and P7 analog and digital
connectors (see Figure 5).
Connect the 4-way ribbon cable and the external EVAL-
ADT7420MBZ printed circuit board (PCB) to
Connector P1 on the EVAL-ADT7420ARDZ shield.
Connect the 6-way ribbon cable and the external EVAL-
ADT7320MBZ PCB to Connector P2 on the EVAL-
ADT7420ARDZ shield.
See Figure 5 for a connection diagram of all of the boards.
LOCATION OF EVALUATION BOARD SCHEMATICS
The evaluation board schematic diagrams and bill of materials
are included with all the supporting documentation on the
EV-
TEMPSENSE-ARDZ product page.
POWER SUPPLIES
The EVAL-ADT7420ARDZ shield is powered by the 5 V power
supply from the Arduino development board and this power
supply is regulated to either 3.0 V or 3.3 V, selected by the
EVAL-ADT7420ARDZ , JP1. The default setting of the power
supply is 3.0 V. Alternatively, the EVAL-ADT7420ARDZ shield
can be powered externally via P10, which is selected by
changing the JP2 jumper Position B.
The EVAL-ADT7420MBZ and the EVAL-ADT7430MBZ
evaluation boards are powered with the same 5 V power supply,
but are selected by P1 and P2, respectively.
