  • IRIV EdgeAI CM5 unit
  • Compatible power supply (see Power Requirements below)
  • HDMI-compatible monitor
  • USB keyboard and mouse

Optional Components​

  • M.2 NVMe SSD for storage expansion
  • Raspberry Pi AI HAT+ for AI acceleration
  • CSI camera modules (22-pin MIPI)
  • CR2032 coin cell battery for RTC

Power Requirements​

The IRIV EdgeAI CM5 supports two power input methods:

ParameterMinMaxUnit
Input Voltage1030VDC
Surge Protection-60V for 20ms-

Use a regulated power supply with adequate current capacity for your application requirements.

USB-C Port (For Development/Basic Applications)​

ParameterValue
Voltage5V
Current5A
ConnectorUSB-C PD capable
caution

When using USB-C power, the LED Driver Terminal outputs (L0 & L1) are not powered. Use VIN terminal power if LED drivers are required.

Power Consumption​

ConditionMax Power
Running stress test (stress-ng --cpu 4 --cpu-method fft)11W

Note: USB load not included in the above measurement.

Terminal Power Connection​

Connect power to the VIN terminal as follows:

  1. Use a DC power supply rated 10-30V
  2. Connect positive (+) to VIN terminal
  3. Connect negative (-) to GND terminal
  4. No earth connection is required

The power input is protected by a 4A fuse. If the device fails to power on, check and replace the fuse if necessary.

Powering On​

From VIN Terminal​

  1. Connect power supply to VIN and GND terminals
  2. Enable the power supply
  3. Observe the PWR LED indicator for confirmation
  4. The system will boot automatically

From USB-C​

  1. Connect a 5V 5A USB-C PD power supply
  2. Press the Power Button once to turn on
  3. Observe LED indicators for power confirmation

Powering Off​

Two methods are available:

MethodAction
Soft ShutdownDouble-press the Power Button
Force ShutdownLong-press the Power Button (5+ seconds)

Alternative method:

  • Press and hold the User Button for 5 seconds

First Boot​

  1. Connect power using either VIN terminal or USB-C
  2. Connect an HDMI monitor to the HDMI port
  3. Connect USB keyboard and mouse to USB 3.0 ports
  4. Power on the device
  5. Wait for the operating system to boot
  6. The OLED display (if connected internally) will show system status

Boot/Run Mode Switch​

The internal Boot/Run switch controls USB-C functionality:

PositionFunction
BootCM5 enters boot mode for OS programming via USB-C
RunNormal operation. USB-C connects to CM5 UART0 via USB-UART converter for console/debug access.

Network Connectivity​

Wired Ethernet​

The IRIV EdgeAI CM5 has two Gigabit Ethernet ports:

PortInterfaceDescription
eth0Native CM5Default 10/100/1000M Gigabit Ethernet
eth1USB 3.0 ControllerSecondary Gigabit Ethernet via USB 3.0

Wireless​

WiFi is available via the CM5's built-in wireless (2.4GHz / 5.0GHz 802.11 b/g/n/ac).

OS Installation / Reflashing​

To reflash the operating system:

  1. Power off the device
  2. Open the enclosure to access the internal board
  3. Set the Boot/Run Switch to Boot position
  4. Connect USB-C cable between the device and your computer
  5. Use Raspberry Pi Imager or rpiboot to flash the OS to eMMC
  6. After flashing, set the switch back to Run position
  7. Reassemble and power on normally
