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 […]
FOSDEM (Free and Open Source Software Developers’ European Meeting) is a 2-day event that usually takes place on the first week-end of February in Brussels, but this year it will be on January 30-31. The event brings thousands of developers, hackers, and other person interested in open source technology who present their projects and share ideas. FOSDEM 2016 schedule is now available, and There will be 557 speakers, 612 events, and 50 tracks this year including 7 main tracks: Distros, Enterprise, Hardware, Communications, Miscellaneous, Office, Systems Administration, and Virtualization. So I’ve had a look at some of the talks, especially out of “Embedded, Mobile and Automotive” and “IoT” devrooms, and prepared my own virtual schedule although I won’t be able to attend. Saturday 10:30 – 10:55 – MIPS, the other side of the embedded by Alexjan Carraturo For many years MIPS processors have been involved in the embedded market, particularly […]
Some LPWAN standards such as SigFox, LoRa, or nWave allows for transmission of data at low bitrate over several kilometers, and I’ve very recently featured Microchip’s LoRa modules and motes in this blog. So when Texas Instruments sent their December 2015 newsletter entitled Wireless MCU spans 20 km on a coin cell, I decided to have a look, and the company’s CC1310 wireless Cortex-M3+M0 MCU based on a proprietary sub GHz technology also claims to last 20-year on a coin cell for applications such as grid communication infrastructure and heat and water meters. SimpleLink CC1310 key features: Microcontroller – ARM Cortex-M3 @ up to 48 MHz with up to 128KB programmable flash, 8KB DRAM for cache/general purpose, 20KB Ultralow Leakage SRAM Sensor Controller – Ultralow power and autonomous; 16-Bit Architecture; 2KB of Ultralow Leakage SRAM for code and data RF core Cortex M0 core with 4KB RAM, and ROM Data […]
Calao Systems is an embedded systems company that I came to know thanks to their Snowball development boards based on the now defunct ST Ericsson Nova A9500 processor. The company has now launched new products for building and home automation powered by Atmel AT91SAM9G20 ARM9 processor clocked at 400 MHz housed in a DIN Rail enclosure. Two products are now available HABA-KNX-EXPLORER and HABA-KNX-LITE that share the following specifications: Processor – Atmel ARM926EJ-S @ 400MHz System Memory – 128MB SDRAM Storage – 256MB NAND Flash, 16 Mbit serial flash, 2Kbit EEPROM with MAC address, and Micro SD slot Connectivity Lite – 1x Ethernet 10/100Mbits Explorer – 2x Ethernet 10/100Mbits USB – 2x USB Host FS (12Mbits), 1x USB Device FS (12Mbits) Serial (Explorer only) – 1x RS-232 (isolated), 2x RS-485 (isolated) Automation I/F – 1x KNX/TP1 (isolated) Expansion – 1x RF Expansion Connector Debugging – JTAG and DBGU interfaces Misc […]
Last year, Microduino successfully launched their tiny Arduino board and shields via Kickstarter, and they are now back on Kickstarter with Microduino Joypad, an other Arduino compatible board that also happens to be a gamepad with a small OLED display. It can be used in standalone to control games on the tiny display, as a gamepad for PC or game console, a control interface for quadcopters and robots etc… Microduino Joypad (main board) specifications: MCU – Atmel ATMega328p/1284p/644p or 32U4 via Microduino Core, Core+, CoreUSB boards. (Not part of board but included in all perks) Display I/F – TFT and OLED headers. Separate TFT display board included in all perks. Controls – Left and right joysticks, 4 buttons, and left and right switches. Audio – Microphone Sensors – Light sensor, temperature sensor USB – 2x micro USB ports: one for power and one for charging Expansions – 2x UPin27 headers for […]
