PCA9959HN-ARD evaluation board

(see

Section 5.5 "Fuji connectors"

). J46 is the Fuji output connector (pin header) and

is located on the top layer of the board. J46 is intended to be mated with a similar Fuji

input connector (J47) on a board mounted directly on top of the first board. In this way,

several boards can be connected in a stack. J47 is the Fuji input connector and is located

on the bottom side of the board, in the same physical place as J46. The first board is

powered and communicates through the Arduino connectors; the other attached boards

draw power and communicate through the Fuji connectors.

Figure 4. PCA9959HN-ARD block diagram

5.4 Arduino port

The connectors J5, J6, J35, and J36 are the mated pin headers of Arduino Uno R3

connectors, having the same electrical function and being placed on the board so that the

daughter board can be directly inserted in the Arduino port. The daughter board circuit

uses only seven signal lines.

Table 2

shows the Arduino connector pins and how they are

used in the circuit (see SPF-46842.pdf schematic file).
