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

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. Key features and specifications: 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 Host interface – USB port Expansion – 7-pin IO header with programming […]

MKR SharkyPro BLE, Zigbee, OpenThread development board follows Arduino MKR form factor

Just a few days ago, we mentioned STMicro launched STM32WB5MMG wireless module to simplify Bluetooth LE, Zigbee, OpenThread connectivity by allowing 2-layer baseboards for the module. It turns out there’s also such a module from a third-party with namely Midatronics SharkyPro module based on STM32WB55, and the company also launched MKR SharkyPro I & II development boards following Arduino MKR form factor. MKR SharkyPro specifications: Wireless Module – SharkyPro module Wireless MCU – STMicro STM32WB55CG/CE dual-core Arm Cortex-M4 core at 64 MHz (application processor) and Arm Cortex-M0+ core at 32 MHz (network processor) with 512KB flash, 256KB SRAM Connectivity – Bluetooth 5.0 LE, Bluetooth Mesh 1.0, OpenThread, Zigbee, and other IEEE 802.15.4 proprietary protocols Antenna – Onboard chip antenna (SharkyPro I) or SMA antenna connector (SharkyPro I) Power 3.3V supply voltage Consumption – 13 nA in shutdown mode, 600 nA in Standby mode + RTC + 32 KB RAM Dimensions […]

STM32WB5MMG Wireless Module simplifies Bluetooth LE, Zigbee, OpenThread connectivity

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. Overview of STM32 Wireless Module The STM32 wireless module is a SiP-LGA86 package (System in Package Land Grid Array) with various external components including: STMicro STM32WB55 Cortex-M4/M0+ wireless MCU LSE crystal HSE crystal Passive components for SMPS Antenna matching and antenna IPD for RF matching and harmonics rejection Key Features of STM32 Wireless Module Dedicated […]

DIY project creates Zigbee to Ethernet bridge with WT32-ETH01

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 […]

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

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 […]

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 […]
