SMLIGHT recently released a Zigbee Ethernet/WiFi/USB coordinator and USB dongle based on the Texas Instruments CC2652P7 or CC2674P10 wireless microcontroller. These update his SLZB-06 Zigbee 3.0 to PoE Ethernet, USB, WiFi adapter from the company and his SLZB based on Silicon Labs EFR32MG21. -07 Zigbee 3.0 USB adapter.
This includes the SLZB-06p7 and SLZB-07p7, which are based on CC2652P7 and designed to work with vendor-independent software such as Zigbee2MQTT and Home Assistant ZHA, and the similar SLZB-06p10 and SLZB-06p10, which are based on CC2674P10. There will be two new devices. According to SMLIGHT, his Zigbee firmware is still under development.
SLZB-06p7/SLZB-06p10 Zigbee to Ethernet/WiFi/USB Coordinator
SLZB-06p7/SLZB-06p10 specifications:
- Wireless SoC
- SLZB-06p7 – Texas Instruments CC2652P7 Arm Cortex-M4F microcontroller @ 48 MHz, 704KB Flash, 256KB ROM for protocol and library functions, 8KB SRAM, integrated +20 dB power amplifier, Bluetooth 5.2 Low Energy, Matter, Thread, Zigbee 3.0
- SLZB-06p10 – Texas Instruments CC2674P10 Arm Cortex-M33 microcontroller @ 48 MHz, TrustZone, FPU, and DSP enhancements, 1024 KB Flash, 8 KB cache SRAM, 256 KB ultra-low leakage SRAM, Bluetooth 5.3 Low Energy, IEEE 802.15.4 PHY and MAC (Zigbee 3..0/Thread/Matter)
- Common – Espressif Systems ESP32-DOWDQ5-V3 dual-core processor @ 240MHz with 448 KB ROM, 520 KB SRAM, 16 KB SRAM, WiFi, and BLE connectivity in RTC
- Connectivity
- Ethernet RJ45 port with PoE support (IEEE 802.3af) implemented via Microchip LAN8720 100M Ethernet controller
- 2.4 GHz WiFi up to 150 Mbps
- Support for Zigbee 3.0, including Zigbee Green Power.
- Thread/matter support
- +5dB SMA antenna included
- USB – USB Type-C port for data and power. USB/UART via CP2102N chip
- Miscellaneous – 4 user LEDs, 1 button
- power supply
- Input – 5V/150mA via USB-C or PoE
- Overvoltage protection, optoelectronic isolation
- Dimensions – 160 x 26 x 22mm
The SLZB-06p7 and SLZB-06p10 Zigbee/Ethernet/USB/WiFi adapters come with a +5dB antenna. These devices are said to work with Home Assistant and Zigbee2MQTT out of the box thanks to the ESP32 firmware preloaded on the board with the following features:
- Zigbee and core firmware OTA updates
- VPN support
- Localization in 15 languages
- Change Ethernet/USB/Wi-Fi adapter mode via firmware or button
- Secure login with username and password
- DHCP or static IP address for Ethernet connections
- Customizable LED behavior
- Responsive web interface based on Bootstrap 5.2
The company still points to an outdated user manual for the original SLZB-06 released in 2022.
SLZB-07p7 and SLZB-07p10 Zigbee 3.0 USB dongle
SLZB-07p7 and SLZB-07p10 Zigbee 3.0 USB dongles are also based on TI CC2652P7 and CC2652P10 Wireless microcontroller with +3Db antenna. It also features the same CP2102N USB UART chip and works with his ZHA integration of Home Assistant and Zigbee2MQTT. In addition to Zigbee connectivity, experimental support for Thread/Matter is also available through Home Assistant. There is more detailed information in the user manual, but as far as I know, all the information is not new and still pertains to the SiLabs model.
SMLIGHT sells SLZB-06p7 for $34.99 and SLZB-07p7 for $9.99. The p10 version is available for an additional $5. You can find these in the SMLight shop and on Aliexpress. Please note that the Zigbee firmware is still under development, so the p10 model is only suitable for developers at this time.
