JetHome Zigbee USB stick ZB6UX v.1 (CC2652P1)

Description

The JetHome ZB6UX stick is designed to work as a coordinator or a Zigbee router and can be used to control other wireless home infrastructure devices operating on the Zigbee protocol as part of a Smart Home controller with the appropriate software installed and configured.

The stick is based on a modern Texas Instruments CC2652P1 multi-protocol wireless microcontroller for the 2.4GHz band (microcontroller description) and is characterized by increased output power of the transmitter.

Main technical specifications:

  • 48MHz Arm® Cortex®-M4F processor;
  • 352KB Flash;
  • 256KB ROM for library functions;
  • 80KB SRAM;< /li>
  • transmitter output power up to +20 dBm;
  • supply voltage 5V from USB;
  • current consumption in active mode is not more than 100 mA.
  • The overall dimensions of the stick in the case without an external antenna: 73 x 21.5 x 10 mm

    Supplied with an external 2.4GHz antenna. The stick can also be used with other external 2.4GHz antennas. To connect an external antenna, use the RP-SMA connector installed on the stick board.

    The stick board also contains: a button for switching the microcontroller boot mode (used to flash the microcontroller), two LEDs (green and red) that can be used to display the stick's operating modes. The operation of the LEDs depends on the firmware installed in the microcontroller stick. On the reverse side of the board there are pads for connecting a debugger (JTAG).

    The stick is intended for use in residential and office premises.

    The Stick comes pre-installed with third-party public firmware or based on it (see p. Supported Firmwares). The manufacturer is not responsible for possible incorrect operation of the stick software.

    Attention! This device is not professional equipment for security and control systems. And it cannot be used on objects that potentially pose a danger to the life and health of others.

    Hardware Features

    The stick is hardware compatible with the original board Texas Instruments LAUNCHXL-CC1352P-2.< /p>

    The transition to the bootloader mode is carried out at a low logic level at the DIO_15 input of the microcontroller. You can control the state of this input using the "FLASH" button installed on the board of the stick. The low logic level at the input DIO_15 is set when the button is pressed.

    The microcontroller pins DIO_28 and DIO_29 are used to control an external RF switch.

    The LEDs are connected to the microcontroller pins DIO_6 (red LED) and DIO_7 (green LED). A high logic level on these pins lights up the corresponding LED.

    The microcontroller communicates with the computer using a Silicon Labs CP2102 USB-UART interface converter chip.

    To control a hardware reset and switch the boot mode of the microcontroller, the DTR and RTS lines of the serial port implemented on the Silicon Labs CP2102 chip are used.

    Body

    The body of the stick is made of FDM plastic, consists of two parts fastened together with latches.

    The body dimensions: 54 x 21.5 x 10 mm.

    Stick Flashing Procedure

    Using a stick with Zigbee2MQTT

    When using the recommended firmware for the coordinator (see p. "Supported firmware"), the stick provides full-fledged work with  Zigbee2MQTT. This firmware, or firmware based on it, is installed by default when the stick is manufactured, and the stick is completely ready to work with Zigbee2MQTT.

    For instructions on installing and configuring Zigbee2MQTT, see website of the project.

    The following parameters must be set in the Zigbee2MQTT configuration file:

    serial:
      port: /dev/ttyUSB0
      
    advanced:
      rtscts: false

    where:

    parameter port: /dev/ttyUSB0 - indicates the file name of the device from the system corresponding to the connected stick. The value of the port parameter may differ from the one specified in this example, depending on the OS used and the number of devices connected to the USB;

    the rtscts parameter: false disables hardware flow control for the specified serial port. This parameter can be omitted, but make sure it is not set to true.
