2. Port specification
2.1 CM4 installation
CM4 module Mounting orientation: “Made in UK” marking on the CM4 module
should face the USB-A port on the Pad 5。Four screws can be used to fix the CM4
module more securely on to the Pad5.
2.2 USB & CANBus mode of Type-C port
To ensure maximum expandability，the onboard Type-C port supports both USB
（EMMC flashing）and CANBus mode。Please refer to switch position of USB/CANBus
mode shown below in the picture.

2.3 Onboard CANBus
When using CANBus Mode，set switch 4（CAN_CS highlighted in picture below）to
ON position(To the left)，the onboard MCP2515 will use GPIO9（MISO）、 GPIO10
（MOSI）、 GPIO11（SCK）、 GPIO8（CS）、 GPIO25（INT）as SPI IO. If you wish to use
said IOs for other functions，Set the switch to OFF position (To the right) to
set the TypeC port to CANBus mode.
2.4 MCU Reset
The board utilizes the MCU to control the conversion of MIPI DSI signal to RGB
signal which controls the onboard screen. If any errors were to occur, please
reset the MCU by pressing the highlighted button in the picture below.
