Weightless Roadmap – Silicon, Modules, SDKs, Base Stations and Networks

The Weightless Standard aims at using the “white space” spectrum, previously used by analog TV broadcasts, for free M2M / IoT communication coupled with low power and cost-efficient hardware offering a range of over 10 km. Longer term the target is to reach $2 hardware cost, and $2 yearly servicing costs. Companies involved with Weightless include Neul, ARM, CSR and Freescale among others. You can read my previous post about Weightless for a longer overview. The Weightless Special Interest Group (SIG) has recently revealed the hardware roadmap for the new standard, which I’ll summarize below. Weightless Chip Neul Iceni, the first weightless silicon, was officially announced in February 2013. The latest version of the chip taped in May 2013 integrates UHF radio operating between 410 and 790 MHz supporting both TV white space and narrowband operation. It is suitable for low volume production applications. A third generation will be taped […]

Ninja Pi Crust Let You Connect Arduino Shields to the Raspberry Pi

There are quite a few projects using both the Raspberry Pi and an Arduino board and its shields together. These are working but the cabling may get messy. People have already found solutions to plug Arduino shields into the Raspberry Pi with products such as Cooking Hacks’ Raspberry Pi to Arduino shield connection bridge (40 Euros) or Open Electronics’ Raspberry Pi bridge (22.50 Euros). Those two boards are fine, but do not include an Atmel MCU, and use Raspberry Pi GPIOs directly, except for their ADC. Another solution is the Paperduino Pi, a DIY Arduino board that can be plugged on top of the Raspberry Pi, and compatible with Arduino shields. But if you want an Arduino board that can easily be stacked between the Raspberry Pi, and Raspberry shield, the upcoming Ninja Pi Crust by Ninjablocks may be an interesting option, especially if you plan to use the 433MHz […]

Silicon Labs Unveils EFM32 Zero Gecko MCU Family Based on ARM Cortex M0+

Silicon Labs, who bought Energy Micro earlier this year, has recently introduced a new family of 32-bit MCU based on ARM Cortex M0+ called EFM32 Zero Gecko, as well as the corresponding starter kit. These ultra low power MCUs (currently 16 products) are destined to be used in IoT applications such as mobile health and fitness products, smart watches, activity trackers, smart meters, security systems and wireless sensor nodes, as well as battery-less systems powered by harvested energy. The key features of this family include: ARM Cortex-M0+ core @ 24 MHz 4kb to 32 kB flash and 2kb to 4 kB RAM memory 17 to 37 GPIO Single 1.85–3.8 V power supply 5 Power modes Hardware AES (Some models only) -40° to 85 °C operation range Package options: QFN24, QFN32 and QFN48 EFM32ZG222F32, the Zero Gecko MCU with the most memory and features, has the following specifications: ARM Cortex-M0+ CPU […]

Broadlink SP1 Wi-Fi Smart Socket Can Be Turned On/Off by Android or iOS Devices

Broadlink SP1 is a smart socket with Wi-Fi connectivity that you can control remotely with your Android or iOS mobile device through a specific app in order to turn on and off lights, water heater, and other electrical appliances. This type of product already exists for example with Belkin Wemo, but Broadlink SP1 is cheaper as it sells for $32.90 including shipping, against $49.99 + shipping for Belkin Wemo Switch. So let’s have a closer look. For this type of device there aren’t that many technical specifications, but they are very important as you need to make sure it matches your electrical grid specs, equipment power rating, and socket type: Material – ABS Power Plug – Three flat-pin plug (Australia type) Voltage – 90~245V @ 50-60 Hz Output Current – 10A Output Power – 2200W Dimensions – 8.9 cm x 7.7 cm x 5.8 cm Temperature Range – -10’C to […]

SparqEE CELLv1.0 Devkit Adds a SIM Card to Your Arduino, Raspberry Pi, or Other Hardware

There are several ways to add wireless connectivity to your sensors, relays, motors, or other devices. Bluetooth, Zigbee and Wi-Fi can all do a good job for short ranges, and the Weigthless standard will eventually provide ranges up to 10km with ultra low power on free spectrum, but it is not available right now, and a good way to achieve longer ranges is to use cellular networks. SparqEE has designed a development kit called CELLv1.0 to add GSM and 3G connectivity to the Internet of things, including (optional) shields for Arduino and Raspberry Pi boards. Here are some technical specifications for the kit: Cellular Networks – WCDMA/HSDPA 2100/1900/900MHz, GSM/GPRS/EDGE 850/900/1800/1900MHz, 384Kbps, DL3.6Mbps HSDPA via ZTE modem Protocols – Data (TCP/UDP), SMS ready Serial interface – Serial (UART, From Cellular Board is 1.8V, From Jumper board is any voltage (ex. 3.3V, 5V)) USB – (power, USART, and modem) Input Voltage – […]

Lantronix Unveils xPico Wi-Fi Module For the Internet of Things

With Texas Instruments SimpleLink Wi-Fi CC3000 and Qualcomm Atheros AR4100P embedded Wi-Fi processors that fully handle Wi-Fi internally, and transfer data to an MCU with an SPI interface, and solutions such as Electric Imp, there are already ways to add Wi-Fi at relatively low cost to appliances. There’s now another solution available on the market with Lantronix xPico Wi-Fi Module. Listed features and specification of xPico Wi-Fi: SoC – ARM Cortex M3 class processor with 1MB on-chip Flash and 128 KB SRAM Storage – SPI Flash storage Wireless LAN Interface IEEE 802.11 b/g and IEEE 802.11n (single stream) WLAN interface (2.4 GHz only) IEEE 802.11 d/h/i/j/k/w/r WPS 2.0 support u.FL connector for external antenna Serial Interface Two Serial CMOS Ports (3.3V, 5V tolerant) 300 to 921.6 Kbps Flow control XON/XOFF, RTS/CTS (SPort 1 only) Lantronix tunneling application (SPort 1 only) Host Interface – Dual Serial Port, SPI, USB 2.0 (device), […]

ARM TechCon 2013 Schedule – ARM Servers, Internet of Things, Multicore, Hardware and Software Optimization and More

ARM Technology Conference (TechCon) 2013 will take place on October 29 – 31, 2013, in Santa Clara, and the detailed schedule for the event has just been made available. In the previous years, the conference was divided into Chip Designs day (1 day), and the other 2 days were reserved for Software & System Design, but this year it does not appear to be the case. Whether you’ll be able to attend the event or not, it’s worth having a look at what will be discussed there in order to have a better understanding of what will be the key ARM developments in the near future in terms of hardware and software. There will be around 90 sessions categorized into 15 tracks: Accelerating Hardware Development – This track explores the resources, tools, and techniques that designers can employ to quickly bring hardware to market. Topics include multicore design, ARM IP, […]
