Features​

  • Do not plug or unplug any devices other than USB and HDMI while the system is powered on
  • The Type-C port can be used as a USB SLAVE interface for flashing images or powering the device
  • Onboard 2 USB port groups, with a total maximum output current of 2A per group (1x USB 3.2 Gen1 + 3x USB 2.0 ports)
  • Supports triple independent displays. When a MIPI DSI driver is added, the system will default to connecting to it regardless of whether a screen is connected, and the screen will display in split-screen mode (depending on the system version)
  • Onboard M.2 M KEY interface, supports NVMe SSD protocol (or PCIe protocol AI modules)
  • Onboard M.2 B KEY interface, supports 4G/5G communication modules
  • Optional versions: 2x RS485 + 2x RS232, or 4x RS485 (isolated)
  • 1x CAN supporting 1Mbps communication rate (isolated)
  • 2x Digital Output + 2x Digital Input (isolated)
  • 3.5mm headphone jack (supports microphone), PH2.0 speaker connector
  • Single controllable buzzer
  • Onboard EEPROM and encryption chip
  • Onboard BOOT button: Press and hold the BOOT button before powering on, then connect to a PC via Type-C to enter flashing mode
  • When using Type-C for flashing, do not connect other devices; otherwise, insufficient power may cause the device not to be recognized
