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 powerdown 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 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 encryption to ensure data security and reliability
  13. Micro SD card slot
    for connecting a Micro SD card with pre-burnt image (Lite variant ONLY)
