WAVIoT LPWAN Technology Powers Low Cost Smart Water and Electricity Meters

With the rise of IoT and M2M applications, more and more Low Power Wide Area Network (LPWAN) standards have been launched or being worked on, such as Sigfox, LoRa, 802.11ah “Hallow”, Weightless, etc… with all promising long range, low power consumption, and support for a high number of nodes. WAVIoT, a US startup founded in 2011, has decided to create its own solution called WAVIoT Nb-Fi (Narrowband Fidelity) that works in ISM bands, offers up to 50km line-of-sight range, supports up to 2 million nodes by gateway, lasts over 20 years on a small battery, and with WAVIoT said to cost as low as $2 per node. The technology is already available in smart electricity and water meters, and modules as shown in the picture below. Here are some of WAVIoT Nb-Fi technical specifications: DBPSK on physical layer of signal transmission; End-nodes transmit radio signal in 10-500 kHz bandwidth Minimum […]

GigaDevice GD32 is a Faster, Software and Pin-to-pin STM32 Compatible Cortex M3 MCU

Las month, Olimex discovered a Chinese company called GigaDevice has made an STM32 clone called GD32 and compatible with STM32F103, but with higher core frequency (108MHz). Olimex has now posted an update after receiving a letter from GigaDevice, and trying GD32F103RBT6 MCU on their own STM32F103 boards. The company explained that GD32 was their own implementation, and claimed rights on GD32 trademarks, while Olimex discovered than GD32 was working just fine on their board having passed “all functional tests without any modifications”, and with all the same development tools and software code running fine. GD32F103xx datasheet (PDF / English version) can be downloaded to find a few more details: The GD32F103xx device incorporates the ARM Cortex-M3 32-bit processor core operating at 108 MHz frequency with Flash accesses zero wait states to obtain maximum efficiency. It provides up to 3 MB on-chip Flash memory and up to 96 KB SRAM memory. […]

Intrinsyc Introduces Qualcomm Snapdragon 820 Cortex-A72-Class Development Board, SoM and MDPs

While there’s already an healthy choice of ARMv8 development board such as LeMaker Hikey, or Qualcomm DragonBoard 410c, all those platforms are based on the lower end Cortex A53 64-bit ARM core, and ARM Cortex A57, let alone Cortex A72, boards are much more difficult to find, as they are much pricier and/or have limited availability. Intrinsyc may have released the first (somewhat) affordable and accessible Cortex-A72-class development board with Open-Q 820 development kit comprised of a SoM and a baseboard, as well as smartphone and tablet mobile development platforms (MDPs) based on Qualcomm Snapdragon 820 quad core Kryo processor. While Kryo is a custom ARMv8 designed by Qualcomm, and not exactly a Cortex A72 core, both have similar performance, as shown in Snapdragon 820 Antutu and Kirin 950 Antutu results. Open-Q 820 board specifications: SoC – Qualcomm Snapdragon 820 quad core Kryo cores with 2x cores @ up to […]

Wio Link is an ESP8266 Board Designed to Make IoT Projects Easier (Crowdfunding)

There are already plenty of board or modules based on Espressif ESP8266 WiFi SoC, but if you don’t like soldering, or would rather avoid breadboards and some cables for your or your kids’ projects, Wio Link may be interesting, as all you need to is to connect Grove modules required for your applications to get started, and Seeed Studio also took care of the low level software part and a drag-and-drop mobile app is provided, so software programming has been made easy too. Wio Link hardware specifications: SoC – Espressif ESP8266EX Tensila SoC Storage – 4MB flash Connectivity – 802.11b/g/n WiFi, with WEP/TKIP/AES encryption support Expansion – 6x Grove connectors: 3x digital, 1x analog, 1x UART and 1x I2C (3.3V I/Os) Power Supply 5V via micro USB port 3.4 ~ 4.2V via external battery Output DC Current – 1000mA MAX Charge Current: 500mA MAX Dimensions – 55mm*48mm Weight – 26g […]

Brillo Android based OS for IoT Projects Supports ARM, Intel and MIPS Platforms

You’d think there are already enough lightweight operating systems that could provide a good enough platform for IoT and embedded projects, but Google decided to make their own Brillo operating system for IoT, based on Android, most probably to leverage the existing Android tools, and make it easier for app developers to move to the Internet of Things space. Brillo ‘s hardware requirements are pretty low as the operating system can run on devices with 32MB of RAM, and 128MB of storage. Google will provide a complete ecosystem with an embedded OS, core services, and a developer kit with tools to build, test, and debug. Just like in Android, three architectures will be be officially supports, starting with the following hardware platforms: ARM – TechNexion Pico-i.MX6UL system-on-module based on Freescale i.MX6 UltraLite and Broadcom BCM4339 802.11ac + Bluetooth 4.0 wireless module, combined with PICO-DWARF baseboard. MIPS – Upcoming MIPS Creator […]
