PCA9846PW-ARD evaluation board
3.2 Assumptions
Familiarity with the I
2
C bus is helpful but not required.
3.3 Static handling requirements
CAUTION
This device is sensitive to ElectroStatic Discharge (ESD). Therefore care
should be taken during transport and handling. You must use a ground strap
or touch the PC case or other grounded source before unpacking or handling
the hardware.
3.4 Minimum system requirements
This evaluation board requires a Windows PC workstation. Meeting these minimum
specifications should produce great results when working with this evaluation board.
•
Computer with Windows 10
• One USB port (either 3.0 or 2.0 or 1.1 compatible)
• One of three EVK boards (MIMXRT1050-EVK, LPC55S69-EVK, 8MMINILPD4-EVK)
along with the associated firmware/GUI software
• USB cable for power and data connection between PC and EVK board (if not included
in the EVK package)

4.2 Kit featured components
Figure 1 and Figure 2 identify the main components on the board. The main elements
are called out. The PCA9846 (U11) is placed in the center of the board. In Figure 1 , the
EEPROMs are indicated along with the corresponding LDOs. The I
2
C address jumpers
(J12, J13) are placed in the upper side of the board. The user can find the power LEDs
(D1-3.3 V, D2-5 V) in the left side.
The Arduino port connectors (J1, J4, J5, J6) are indicated in
Figure 2 , on the bottom side
of the board.
