$7 ITEAD Zigbee 3.0 USB dongle features Silicon Labs EFR32MG21 MCU

Zigbee 3.0 USB dongle

ITEAD is known for its Sonoff home automation products that started with ESP8266 WiFi and/or RF connectivity several years ago, but more recently the company started to offer Zigbee compliant products including Sonoff BASICZBR3 smart switch, Sonoff ZBBridge WiFi to Zigbee Gateway, or a cheap $4 CC2531 Zigbee USB Dongle compatible with Zigbee2MQTT open-source firmware. The company has now launched a more powered Zigbee 3.0 USB dongle, yet still affordable at $6.99, based on the same Silicon Labs EFR32MG21 wireless MCU as used in the Sonoff ZBBridge with a faster core, more RAM, and a more powerful radio.

STM32WB5MMG Wireless Module simplifies Bluetooth LE, Zigbee, OpenThread connectivity

STM32WB5MMG Wireless Module

The STM32WB5MMG (STM32) is a wireless microcontroller module by STMicroelectronics. It is a compact ultra-low-power module that allows customers to design 2-layer PCBs and integrates everything up to the antenna, including an IPD (integrated passive device) for reliable antenna matching in order to reduce the overall costs. The STM32 wireless module is compatible with BLE (Bluetooth Low Energy) 5.0, OpenThread, Zigbee 3.0, dynamic and static concurrent modes, and 802.15.4 proprietary protocols. It also supports simultaneous dual-protocol mode that allows IEEE 802.15.4 radio-based protocols like Zigbee 3.0 and OpenThread for direct connection with any BLE device.

DIY project creates Zigbee to Ethernet bridge with WT32-ETH01

DIY Ethernet Zigbee Coordinator

We previously wrote about Ebyte E180-ZG120B-TB an inexpensive ($9.90) Zigbee 3.0 evaluation board based on Silabs EFR32MG1B Arm Cortex-M4 wireless MCU and the equally cheap ($7.78) WT32-ETH01 ESP32 Ethernet board. What do they have in common? Absolutely nothing! But GitHub user tube0013 decided to connect both boards over UART to create a Zigbee to Ethernet DIY coordinator/bridge running open-source firmware. The hardware also includes a Micro USB adapter for power, several 10cm jumper wires, and he/she also designed a 3D printed case. EZSP-Firmware is used for the Ebyte Zigbee 3.0 board, and ESPHome open-source home automation firmware for the ESP32 board. You’ll also need serial to IP code and ESPHome config. Note that flashing firmware to the Ebyte requires a programmer, and the developer used a J-link EDU Mini together with Silicon Labs’ Simplicity Commander. As mentioned above, a 3D printed case has also been designed, so everything is neatly packed together. The total cost assembled should be around $20. […]

Telink TLSR9 Wireless Audio & IoT RISC-V SoC integrates RISC-V DSP/SIMD P-extension

Telink TLSR9 Development Board

At the end of last month, there was a lot of buzz about Bouffalo BL602, one of the first RISC-V SoC with built-in wireless connectivity, namely WiFi 4 and Bluetooth 5.0 LE. We should expect more and more of those types of solutions, and Telink & Andes jointly introduced TLSR9-series of wireless audio chips for hearables, wearables, and other high-performance IoT applications. The chips are powered by an Andes D25F RISC-V 5-stage core that happens to be the first core to integrate RISC-V DSP/SIMD P-extension and offer Bluetooth 5.2, Zigbee 3.0, HomeKit, 6LoWPAN, Thread, and/or 2.4 GHz proprietary protocol. The press release focuses on the Andes core, but an article in Chinese allows use to find more about Telink TLSR9 family’s key features: CPU – Andes D25F 32-bit RISC-V 5-stage core @ up to 96 MHz (2.59 DMIPS/MHz and 3.54 CoreMark/MHz) with RISC-V DSP/SIMD P-extension Optional NNU – AI engine supporting DNN, LSTM, and RNN neural networks Memory/Storage – 256KB […]

STMicro launches cheaper STM32WB30 and STM32WB35 Bluetooth LE & Zigbee MCUs


STMicro introduced the first wireless STM32 microcontrollers in 2018 with STM32WB Cortex-M4/M0+ MCU family equipped with Bluetooth 5.0 and 802.15.4 radios, and they followed earlier this year with STM32WL Cortex-M LoRa SoC. The company has not just announced yet another wireless STM32 family but instead added the more affordable STM32WB35 and STM32WB30 chips that can be obtained for under $2 in quantities. The new STM32WB microcontroller enabled a low BOM cost thanks to their memory configuration. Specifically, STM32W30 comes with 256KB flash while STM32W35 features 512 KB flash, and both offer 96 KB of RAM. This compares to STM32WB55 will up to 1MB flash and 256KB of RAM. Apart from the lower memory and flash capacity, the new wireless MCUs have basically the same features as other members of the STM32WB family with 16-bit ADC, quad-SPI interface (STM32WB35 only), as well as Bluetooth Low Energy 5.0, Zigbee 3.0, and OpenThread (802.15.4) certified stacks. Features of STM32WB30 corresponds to the one […]

STMicroelectronics Introduces Zigbee 3.0 to the STM32WB55 microcontrollers

STMicroelectronics has added Zigbee 3.0 support to its STM32WB55 wireless microcontroller family using the Zigbee PRO protocol stack. The STM32 Wireless MCU (STM32WB55) was launched last year with a dual-core Arm Cortex-M4 CPU and Cortex M0+ core, as well as  Bluetooth 5 and 802.15.4 radios. STMicro is hoping to expand the applications of the STM32WB into areas like home automation as Zigbee 3.0 is making brands choose Zigbee for their smart-home connectivity solution, smart-lighting, smart-building, mesh IoT connectivity, and many more. The STM32WB55 microcontrollers already provide support for Thread and Bluetooth 5.0 and the inclusion of the Zigbee connectivity will take this to the next level. The STM32WB55 Zigbee 3.0 software includes support for the Exegin Zigbee PRO protocol stack which is available for free. To ease development and deployment, STM32WB Zigbee solution supports 46 Zigbee 3.0 clusters and a further 21 clusters support legacy products and with the Zigbee 3.0 ZCL, developers can easily speed up their certification process thereby […]
