    What's On Board

    1. CM4 socket
      suitable for all variants of Compute Module 4
    2. IO-VREF
      Set the CM4 IO logic level as 3.3V (default) or 1.8V
    3. RTC-12C: 12C bus selection for RTC
      Can choose SDA0 & SCLO (default) or GPIO2 & GPIO3
    4. RTC INT: RTC interrupt pin select
      D16: Use GPIO16 to receive interrupt signal when RTC interruption (default)
      GL-EN: CM4 power-down on RTC interruption
      PI-RUN: CM4 will reboot on RTC interruption
    5. SYSTEM: System function configuration
      WP-DIS: Prevent EEPROM from being overwritten
      BT-DIS: Disable Bluetooth function, for CM4 with antenna variant ONLY
      WIFI-DIS: Disable WiFi function, for CM4 with antenna variant ONLY
    6. Boot
      ON: CM4 will be booted from the USB-C interface
      OFF: CM4 will be booted from eMMC or Micro SD card
    7. PWR & USB
      When the BOOT switch is "ON", can be used as the USB programming or DC power supply port
      When the BOOT switch is "OFF", only used as the DC power supply port
    8. HDMI0
      HDMI port supports 4K 30fps output
    9. USB
      2x USB 2.0, for connecting sorts of USB devices
    10. ETHERNET0
      CM4 original Gigabit RJ45 ETH
    11. ETHERNET1
      USB extended 100M ETH
    12. CAM0 & CAM1
      2x MIPI CSI camera ports
    13. Buzzer
      GPIO22 control
     
    1. FAN
      4-pin FAN header, only supports 5V FAN, allows PWM speed adjustment (GPIO18 control, speed measurement is not supported)
    2. RTC battery socket
      Supports CR1220 button cell
    3. RS485 TX/RX indicator
      TXn: TX indicator for channel n
      RXn: RX indicator for channel n
    4. User LED
      USER0: GPIO20 control
      USER1: GPIO26 control
    5. PWR
      Raspberry Pi power indicator
    6. ACT
      Raspberry Pi working status indicator
    7. DC 7~36V
      DC power supply interface
    8. Power input terminal
      DC power supply terminal supports 7~36V wide range power input
    9. RS485 terminal
      4 x Isolated RS485 terminal with a spacing of 5.08mm
    10. Jumper
      120R Balance Resistor Selection Jumper
    11. RS485 operating mode selection
      Full-auto: automatic mode, easy for program operation but the load capacity is weak
      Semi-auto: semi-automatic mode, which requires manual TX/RX switching, with high reliability and strong load capacity
    12. Encryption chip
      ATSHA204 encryption chip, providing multiple encryptions to ensure data security and reliability
    13. Micro SD card slot
      for connecting a Micro SD card with a pre-burnt image (Lite variant ONLY)
