JetHome ZB3CX Zigbee Module (CC2538+CC2592)

The JetHome ZB3CX module is based on a reference design from Texas Instruments CC2538-CC2592EM-RD using a wireless microcontroller TI СС2538

The module is designed to work as part of automation devices (controllers, end devices) and, depending on the software installed on the module, can perform various functions.

The distinctive features of the module are the ability to connect via USB interface and increased transmitter power.

Supported protocols

  • Zigbee

  • 6LoWPAN

Technical Specifications

  • Microcontroller ARM® Cortex®-M3 32 MHz.

  • RAM 32 KBytes.

  • Pins 5…8 (PB1…PB4) - depending on the software can be used to connect LEDs or for other purposes.

Software

Supported firmware

Module flashing procedure

Note

Before flashing, the module must be switched to bootloader mode (serial bootloader). To do this you must reset the module by holding the logic low at the PA7 input of the microcontroller (pin 20 of the module).

Return of the module to operation mode is performed when the module is turned on/restarted when the logic level at pin PA7 (pin 20 of the module) is high.

Limitations

Warning

  • The device is shipped and supported with coordinator firmware only.

  • You are responsible for using third-party firmware, including router firmware.
