ITEAD has just released a new Zigbee 3.0 dongle powered by the Silicon Labs EFR32MG21 wireless MCU.
The Shenzhen-based company, well known for its Sonoff line of home automation devices, had recently introduced a number of Zigbee compliant products like the Sonoff BASICZBR3 smart switch, the Sonoff ZBBridge WiFi to Zigbee Gateway, and the Zigbee-compatible USB dongle.
ZigBee 3.0 USB Dongle is pre-flashed with the Silicon Labs Zigbee stack from their EmberZNet 6.7.8 SDK as the application firmware, which means that it can be used out of the box as a ZigBee coordinator on Home Assistant and openHAB,” ITEAD writes.
The Silicon Labs EFR32MG21 wireless MCU used in the ZigBee 3.0 USB adapter is a high-performance, low-power chipset designed to increase processing capability, improve RF performance, and lower active current. It is a very powerful MCU the same as the one used in the Sonoff ZBBridge, but this time with a faster core, more RAM, and a more powerful radio.
Key Features and Specifications of the ZigBee 3.0 USB Dongle Include:
- Wireless MCU: Silicon Labs EFR32MG21 Arm Cortex-M33 microcontroller @ up to 80 MHz with DSP and FPU, up to 1024 kB flash, up to 96 kB RAM, 2.4 GHz IEEE 802.15.4 for Zigbee or Thread
- USB port (host interface)
- 7-pin IO header with programming pins, one GPIO, 3.3V and GND
- 2-pin header for Tx/Rx serial port
- Button and reset buttons
- LED
- PCB antenna
- Power Supply: 5V via USB port, LDO chip
- Dimensions: 56 mm x 14 mm
- Weight: 5 g
