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), […]

$275 HackRF Open Source Software Defined Radio (SDR) Platform

HackRF is an open source hardware project to build a Software Defined Radio (SDR) supporting a frequency range between 30 MHz and 6GHz in both directions (Tx and Rx, half-duplex) with a maximum bandwidth of 20MHz. Jawbreaker (shown below) is a beta hardware that has been tested by several developers and beta testers, and applications such as Digital Audio Broadcasting (DAB), Bluetooth monitoring, spectrum sensing, wireless microphones, AIS, FM radio, etc.. have already been ported to the platform. In order to lower the cost of the hardware, Michael Ossmann has launched a Kickstarter campaign to fund mass production. There seems to be many SDR enthusiasts as the campaign has already reached its funding target ($80,000) and received for over $300,000 in ledges. What is Software Defined Radio (SDR) and What Can it Be Used for? Before providing details about the hardware and software, it may be useful to provide some […]

MC HCK is a $5 ARM Development Board Powered by Freescale K20 MCU

MC HCK (pronounced McHack) is a tiny and cheap development board powered by Freescale K20 MCU (ARM Cortex M4) that can be easily programmed via USB. The board has been designed with KiCad, is fully open source hardware, and it’s supposed to cost as low as $5. The only problem, or main advantage, depending on how you look at it, is that it’s not available for sale (yet), but instead you’ll need to make it yourself. The actual cost of doing so will be well over $5 (About $35), but the BoM cost is about $5, and you can make 5 boards for this price, or about $7 per board. The detailed steps are explained on McHck blog, but they can summarized as follows: Order 10 PCB using the gerber files via services such as Seeedstudio or Iteadstudio Order 5 free samples of Freescale K20 MCU. Select MK20DX128VLF5 part, and […]

Beyond Semiconductor Announces BA21 Processor Core for Embedded MCUs

Beyond Semiconductor, a Ljubljana, Slovenia based company, has recently announced BA21, a 32-bit processor core, with 2.5 Coremark per megahertz, and clocked up to 125 MHz, that’s roughly equivalent to a Cortex M3 core @ 120 MHz. Target applications include mixed signal embedded processing, wireless communications ICs (e.g. Bluetooth, Zigbee, GPS), industrial Microcontrollers, and battery-powered or ultra-low-cost devices.If you’ve never heard about Beyond Semi, you may want to read my previous article about their BA25 core (Cortex A7/A8 equivalent) for a bit more details about the company. Here are the key features of BA21 core: 32-bit Processor Small silicon footprint (less than 10k gates) for lower leakage and dynamic CPU power Two-stage pipeline architecture Extreme Code Density for lower instruction fetching energy Advanced power management Dynamic clock gating and power shut-off of unused units Software- and hardware-controlled clock frequency Wake-up on tick timer or external interrupt Performance Up to 2.5 […]
