Digi Launches XBee-PRO 900HP RF Module With a Range of Up to 45 Km

Digi International has recently announced the XBee-PRO 900HP RF embedded module based on ADF7023 transceiver and Energy Micro Cortex-M3 EFM32G230 MCU @ 28 MHz. The company claims the module supports a line-of-sight range of up to 45 km with a high-gain antenna and data rates of up to 200 Kbps.45 km is not quite enough to communicate in space (100 km), but that’s still a pretty good range. Indoor / urban range is up to 600m. Here are the hardware specifications of XBee-PRO 900HP module: Processors – ADF7023 transceiver and Cortex-M3 EFM32G230 @ 28 MHz Frequency Band – 902 to 928 MHz, software selectable channel mask for interference immunity Antenna Options – Wire, U.FL and RPSMSA RF Data Rate – 10 Kbps or 200 Kbps Indoor/Urban Range – Up to 2000 ft (610 m) Outdoor/ Line-Of-Sight Range – Up to 9 miles (14 km) w/ dipole antenna; Up to 28 […]

ARM TechCon 2012: Software & System Design Schedule

ARM Technology Conference (TechCon) 2012 will take place on October 30 – November 1, 2011, in Santa Clara, and UBM Electronics has already posted the detailed schedule for the event. The first day (October 30) will be Chip Designs day and the other 2 days will focus on Software & System Design. Even if, like me, you are not be able to go there, it’s still interesting to know what will be discussed at the conference, to have a better idea where ARM is going, and what new technologies and/or development techniques are (or will become) available. There will be around 70 sessions categorized in 15 tracks: Android / Open Source – Development tools, middleware for native application development, and optimized drivers for Android, Linux, FreeRTOS etc … Compute Platforms – Development and implementation of standards and specifications, from board/module design to consumer and server designs Developing / Debugging – […]

Freescale Announces Kinetis KW20 Cortex M4 MCU with Built-in Zigbee Transceiver

Freescale announced the addition of the Kinetis KW20 to its Kinetis microcontroller portfolio. The Kinetis KW20 is based on ARMCortex-M4 core and MC13242 RF transceiver to deliver a single chip Zigbee solution for the Internet of Things and power applications such as smart energy, smart metering and building control. The company explains that their new wireless MCU family aims to “address the increased processing and memory requirements associated with future ZigBee Smart Energy 2.0 and Internet Protocol specifications”. The KW20 supports dual personal area network (PAN) to enable a single device to communicate wirelessly on two ZigBee networks. This feature eliminates the need for multiple radios required to connect different home automation and smart energy networks. Kinetis KW20 wireless MCU features: ARM Cortex-M4 processor core Up to 512 KB of flash memory and 64 KB of RAM Cryptology accelerator and sophisticated tamper detect Integrated IEEE 802.15.4-compliant radio (MC13242 RF transceiver) Low […]

25 USD Hacker Friendly Electric Imp “WiFi-ises” Your Coffee Machine

Electric Imp is a device in an SD card form factor that aims at providing Wi-Fi connectivity to household appliances at low cost and bringing the Internet of Things (IoT) closer to reality. The Imp will also connect to a Cloud service handled by the company (which is also called Electric Imp). The device Wi-Fi connection can easily be configured using an iOS or Android smartphone thanks to BlinkUp, a patent-pending scheme supporting WEP, WPA and WPA2 encryption schemes as well as WPS setup. Electric Imp developers expect this device to save resources (e.g. electricity) by taking into account environmental conditions (e.g. occupancy, temperature..), improve security & safety and overall provide better monitoring and control of devices. For example, this could enable support services to remotely diagnose a device, and provide timely customer support. Here are the Electric Imp hardware specifications: ST Micro STM32 Cortex M3 MCU 802.11b/g/n WiFi 6 […]

Microchip Unveils Wi-Fi Comm Demo Board with 32-bit PIC32 MCU

After TI and Qualcomm, here’s another WiFi solution for MCU aimed at the internet of things (IoT). Yesterday, Microchip Technology announced the Wi-Fi Comm Demo Board, which combines a Microchip 32-bit PIC32 microcontroller (PIC32MX695F512H) with a low-power MRF24WB0MA embedded Wi-Fi radio transceiver module. This small (and cheap) demo board can be used to integrate with existing embedded designs and/or to evaluate Wi-Fi connectivity with a 32-bit MCU. Contrary to TI and Qualcomm, the IP network stack is not implemented in hardware, but Microchip provides a TCP/IP stack that can be freely downloaded at http://www.microchip.com/get/A3VP. This TCP/IP stack includes HTML, DHCP, DNS, IPv4/v6, SSL, etc… (See diagram below) The memory footprint is 28-34 KB depending on the modules used. I could not find details about power consumption, but the company claims their solution can also run with just 2 AAA batteries. Microchip explains that this solution can enable the rapid growth […]
