JetHome Zigbee module ZB6C v.1 (CC2652P1)


The JetHome ZB6C module is based on a modern multi-protocol wireless microcontroller for the 2.4GHz band Texas Instruments CC2652P1  and is characterized by high performance of the computing core and increased output power of the transmitter.

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.

Supported protocols:

  • Zigbee;
  • Thread;
  • Bluetooth 5.2 Low Energy;
  • IEEE 802.15.4;
  • 6LoWPAN.


Main technical specifications of the module:

  • 48MHz Arm® Cortex®-M4F processor;
  • 352KB flash memory;
  • 256KB ROM for library functions;
  • SRAM 80KB;
  • transmitter output power up to +20 dBm;
  • supply voltage 3.3V;
  • current consumption in active mode up to 85 mA.
  • The overall dimensions of the module: 28 x 18 mm

The module is hardware compatible with the original board Texas Instruments LAUNCHXL-CC1352P-2  and is designed to be compatible with standard firmware from TI or from the Zigbee2MQTT project (see below).

To control the RF switch installed on the module, the microcontroller pins DIO_28 and DIO_29 are used

Assignment of module pins

The module is made in the format of a unified JetHome wireless module 28 x 18 mm in size with contacts located along the perimeter of the module. Module pin assignment (top view):

  • Pins 1,2,3,4 are reserved for connecting a JTAG debugger;
  • Pin 20 (DIO_15) is reserved for use as a bootloader backdoor. The bootloader mode is entered by a low logic level on this pin;
  • Pins 5, 6 (DIO_7, DIO_6), depending on the software, can be used to connect LEDs or for other purposes;
  • Pins 16, 17 (DIO_12, DIO_13) - UART interface for firmware and communication with the module;
  • Pins 18, 19 (DIO_5, DIO_21) are reserved for connecting peripheral devices via the I2C bus;
  • Pins 10, 11, 12 are not used.

Module software

For information on supported firmware, see the documentation: Software for sticks and modules based on the TI CC2652P1 chip< /a>

Module flashing procedure

The cc2538-bsl utility can be used to flash the module (see Firmware for TI modules and sticks CC2538/CC2652 using the cc2538-bsl)

The module must be switched to serial bootloader mode before flashing. To do this, it is necessary to reset the module by holding a low logic level at the DIO15 input of the microcontroller (terminal 20 of the module). The module is switched back to the operating mode when the module is turned on/rebooted at a high logic level at the DIO15 pin (module pin 20).

This is true only for firmware recommended for installation (see the "Module software" section).
