RS-485 Half Duplex
Use adapter 2.54 10P to DB9P Male (WF228) or connect the phyBOARD Pollux to the periphery via a DB9 cable.
Connecting the CAN Interfaces
There are two CAN-FD transceivers providing CAN and CAN-FD (CAN flexible datarate) up to 8 Mbps.
The processor FLEXCAN1 is connected to the X3 transceiver. FLEXCAN2 is connected to the X4 transceiver. Additionally, X3 and X4 deliver a +5 V
voltage source at pin 9.

Use adapter 2.54 10P to DB9P Male (WF228) to connect the phyBOARD-Pollux to your periphery via a DB9 cable. Remove JP1 (and optionally JP2) if the
120 Ohms termination is not needed in your CAN topology.
Connecting USB
Connect your USB3.0 Device to one of the two host sockets of X5. The lower socket is connected via a USB hub to USB2 of the i.MX 8M Plus. The upper
socket is directly connected to USB1 of i.MX 8M Plus. By using a 1:1 USB cable, the upper socket can be used as OTG too.
Connecting to the Ethernet
Connect the Ethernet cable to the Ethernet ETH0 port (X9) on the phyBOARD-Pollux. Connect the other end to a suitable Ethernet source (10/100/1000),
as the development host will need to communicate with the phyCORE-i.MX 8M Plus.
The ETH1 port (X8) is not working in the Alpha Kit.
Connecting a phyCAM-M camera module
The processors MIPI CSI-2 interface (CSI1) is brought out on connector X11 as a phyCAM-M interface. Connect a VM-016 camera module via WF271
30P-FFC to use with the phyBOARD-Pollux.
The CSI2 interface on connector X12 is not working in the Alpha Kit.
Connecting LVDS Display and Touch-Screen
Use the cables
to connect the Display (AC168) to the phyBOARD-Pollux. WK475 is needed for the Backlight. Connect
WK475, WK476, and WK477
WK475 to X26 on the phyBOARD-Pollux. WK476 in needed for the LVDS Data-Lanes and configuration. Connect WK476 to X24 on the phyBOARD
Pollux. WK477 is optionally needed for Display-Touchscreen. If needed connect WK477 to USB-Host Connector X5.
Connecting WLAN Adapter PEB-WLBT-05-UCon.A0
PEB-WLBT-05-UCon.A0 connects to phyBOARD-Pollux at Expansion Connector X6 (pin 1 to pin 50 pin 51 to pin 60 are not connected).
Powering the Board
It is recommended to power the phyBOARD-Pollux with the power supply (SV055) included in the kit. Connect the power supply to the Power-In connector
(X23).
Warning
Do not modify JP3 or JP4 while the board is powered.
Tip
RS-232 DTE (data terminal equipment) means that TXD and RTS are outputs, RXD und CTS are inputs
