Introduction🔗

The PAN W602-2C M.2 device is an evaluation device that is suited for the use of the PAN W602-2C module in conjunction with host processor evaluation kits that have a M.2 Key E socket.

There is no dedicated M.2 device for the single-band PAN W602-1C module. But you can use this M.2 device instead and restrict the function range to single-band in software.

Early Samples

You might have received an early sample of this evaluation device, which may look different and might have additional or missing interfaces.

However, the basic functionality is the same as it is described in this user guide.

Features🔗

  • M.2 Key E connector
  • SWD interface ('Tag Connect')

2 SWD interface
You can use the SWD interface for testing and debugging the CC3351 controller.

3 Mounting screw hole
You can use the mounting screw hole to secure the board in a M.2 Key E socket. Also see Mounting the Device

4 M.2 Key E connector
You can insert the M.2 device into a M.2 Key E socket to connect the modules interfaces to a host processor. Also see M.2 Connector Pin Map

5 Status LED
You can observe the current status of the device using this LED.

Initial Preparations🔗

Mounting the Device🔗

To mount the PAN W602-2C M.2 device in a M.2 Key E socket on a host board execute the following instructions.

  1. Line up the notch on the M.2 Key E connector 4 with the key of the M.2 Key E socket of the host board.

  2. Insert the PAN W602-2C M.2 device into the socket slightly angled.

  3. Apply some light downward pressure until the PAN W602-2C M.2 device is parallel to the host board and makes contact to the threaded insert.

  4. Insert a M2.5 x 4 machine screw into the mounting screw hole 3 and the threaded insert.

    The PAN W602-2C M.2 device is secured in place.
