ARDUINO CONNECTOR
The EVAL-ADUCM420QSP1Z has Arduino R3 headers
directly compatible with Arduino Uno and Arduino Zero. The
Arduino pins used by the EVAL-ADUCM420QSP1Z board are
given in Table 3.
For more information on the ADuCM420 pins, refer to the
ADuCM420 data sheet and ADuCM420 hardware reference
manual (UG-1807) .
By default, the EVAL-ADuCM420QSP1Z board is configured as
an Arduino slave board, with connectors populated only on the
component side of the PCB.
If the EVAL-ADuCM420QSP1Z board is to be configured as an
Arduino host, populate a different connector type on the solder
side with the following guidelines:
•
P16 and P19: 8-pin, single-row headers, 2.54 mm pitch (for
example, the Samtec SSQ-108-03-G-S)
•
P21: 6-pin, single-row header, 2.54 mm pitch (for example,
the Samtec SSQ-106-03-G-S)
•
P13: 10-pin, single-row headers, 2.54 mm pitch (for
example, the Samtec SSQ-110-03-G-S)
Figure 3 shows the appropriate connector type. For proper slave
adapter connection, ensure the female part is on the solder side
with the long pins protruding through to the component side.
