ConBee - USB Dongle
2016-06-15
1. Overview
The ConBee is the platform independent USB Dongle that turns your host into a full
functional wireless node which can be seamlessly integrated into ZigBee networks. This will
enhance the application range of your host with monitoring and controlling ZigBee networks.
ZigBee compatible devices are available from a lot of manufacturers.
This USB Dongle contains a powerful radio module with integrated power amplifier and low
noise amplifier. Together with the assembled onboard chip antenna which has been
optimally tuned ensures a superior RF performance.
The ConBee is shipped with a bootloader application for simple firmware uploads and
updates.
The ZigBee firmware is interfaced by a software called deCONZ which runs on Windows,
Linux and Mac OS X and is responsible for ZigBee network control and monitoring.
Basically, the USB Dongle is a reference design for the ZigBee radio module deRFmega25623M12 by dresden elektronik.
2. Applications
Mainly the ConBee is designed to handle ZigBee Light Link (ZLL) and ZigBee Home
Automation (ZHA) applications in connection with the ZigBee firmware and software
deCONZ. A more detailed description of the ZLL standard, the features, benefits and
available certified products can be found on the official alliance website [1].
It is also possible to use a custom firmware for wireless applications. Follow the instructions
in Section 5 and Section 10 for detailed instructions on software installation and customer
modifications.
Note:
Please note that depending on the modifications the radio certification and
compliance may become invalid. Please get in contact with us to advise you
for a custom FCC certified and/or compliant design.

3.2.
How does the USB Dongle work?
The functional parts of the ConBee are shown in a schematic overview in Figure 2.
The USB Dongle will be supplied by the USB 5.0 V domain. Therefore the USB power supply
must be sufficient to support the additional load. An onboard low-drop-out voltage regulator
generates a stable 3.3 V voltage to supply the radio module on the USB Dongle.
The onboard placed radio module deRFmega256-23M12 by dresden elektronik contains an
8-bit AVR microcontroller with an integrated low-power 2.4 GHz transceiver for ZigBee and
IEEE 802.15.4 applications. The ConBee has no pre-installed firmware. You can install the
firmware that fits your needs. Each USB Dongle contains a world-wide unique identifier,
named MAC-ID. It consists of an 8 byte address, including the vendor ID and product ID. The
MAC-ID is stored in the MCU internal EEPROM.

8. Hardware modifications for development
Besides the factory-default USB Dongle configuration it is also possible to modify the
hardware to enhance its functionality.
8.1.
Assemble the program header
The program header provides the microcontroller programming interface of the radio module.
Assemble a 50 mil 10-pin SMT header on the bottom side. We recommend the use of the
header FTSH-105-04-LM-DV-P by SAMTEC or a similar item.
The header pin description can be found in Section 8 Table 11 . A detailed description of
suitable programmers and related software tools are listed in [5].
Program header footprint

Note:
8.2.
Improper handling in respect of erasing or overwriting the MCU internal flash
or EEPROM completely or in parts may result in an unusable USB Dongle
unit. Modification of the pre-allocated EEPROM memory sections or removal
of the pre-installed bootloader will irreversibly preclude restoring, booting or
upgrading the shipping firmware at all. dresden elektronik will not support such
modifications (see Section 5.3 for details).
Assemble the trace header
The trace header provides the microcontroller UART interface of the radio module. Assemble
a 50 mil 6-pin SMT header on the bottom side. We recommend the use of the header FTSH103-01-F-DV by SAMTEC or a similar item.
The header pin description can be found in Section 8 Table 11.

8.3.
Assemble the Serial Flash Memory
The USB Dongle offers the use of an external Serial Flash Memory for custom application or
features. The memory interface is connected to the SPI of the radio module. The provided
footprint is SO-8. We recommend the use of a Serial Flash Memory like M25P40-VMN6TPB
by MICRON. It is useful to place a stabilizing capacitor of 100nF to the 0402 footprint next to
the memory.
The signal pin description can be found in Section 8 Table 10.

Assemble the User button
The USB Dongle offers the use of an external user button. We recommend the use of the
SMT button KSR211GLFS by ITT or similar items. The button is connected with ground and
signal PB7.
The signal pin description can be found in Section 8 Table 10Table 11.

Assemble the status LEDs
The USB Dongle offers the use of two status LEDs. The first LED is connected with signal
PD7 and the second LED is connected with signal PG2. Each LED needs one additional
series resistor with a value of 820 Ohms. Both LEDs are low-active. We recommend the use
of the following LEDs and resistors:

Red low current LED: TLMS1000-GS08 by Vishay (SMT package 0603)

Green low current LED: LG L29K-G2J1-24-Z by OSRAM (SMT package 0603)

Resistor 820 Ohms: RC0402FR-07820RL by YAGEO (SMT package 0402)
The signal pin description can be found in Section 8 Table 10.
