    • I²C - Soldering the onboard jumpers routes I2C0 to this slot.
    • UART - Soldering the onboard jumpers routes UART0 to this slot.

M.2 Key B Slot​

  • General
    The M.2 Key B slot is primarily intended for cellular modems (LTE/5G) and storage modules on Jetson platforms. When using an LTE modem, the SIM card slot on the carrier board connects to this port. It can also support certain SSDs or expansion cards depending on routing.

  • Supported Form Factors

    • 2242 Modules.
    • 3042 Modules.
    • 2230 Modules with a mechanical adapter to 2242/3042.

  • Supported Modules

    • 4G LTE.

  • Implemented Interfaces (per M.2 standard)

    • USB 2.0 - Connected over an onboard USB hub.
    • SIM-CARD - Connected to the onbaord SIM-CARD slot.

Software​

General​

  • The software installation for the Lumen board is simple and based on the same steps as the Dev Kit board.
  • NOTE: The SD card slot is for storage only and doesn’t support flashing an operating system.
