SiFive Introduces Freedom U500 and E500 Open Source RISC-V SoCs

Open source used to be a software thing, with the hardware design being kept secret for fear of being copied, but companies such as Texas Instruments realized that from a silicon vendor perspective it would make perfect sense to release open source hardware designs with full schematics, Gerber files and SoM, to allow smaller companies and hobbyists, as well as the education market, normally not having the options to go through standard sales channels and the FAE (Field Application Engineer) support, to experiment with the platform and potentially come up with commercial products. That’s exactly what they did with the Beagleboard community, but there’s still an element that’s closed source, albeit documented: the processor itself. But this could change soon, as SiFive, a startup founded by the creators of the free and open RISC-V architecture, has announced two open source SoCs with Freedom U500 processor and Freedom E300 micro-controller. Freedom […]

WiThumb is an ESP8266 WiFi USB Adapter with Motion and Temperature Sensors (Crowdfunding)

There are now plenty of Espressif ESP8266 boards or module to play with, but most of them require some cables or wires, at least for power. WiThumb does not need any of that as it’s designed to be plugged into any USB ports, and includes a 6-axis motion sensor, and a temperature sensor. WiThumb USB dongle specifications: SoC – Espressif ESP8266 32-bit MCU with 802.11b/g/n WiFi Storage – 4MB Flash memory Sensors – Temperature sensor (+/- 0.25C typical accuracy, -40 to 125 C range), 6-axis gyroscope + accelerometer Expansion – Breadboard friendly through holes with 1x 10-bit ADC, I2C and 4x GPIOs USB – USB type A connector Misc – Reset and flash buttons Power – 5V via USB port Dimensions – 4.8 x 2.2 cm The USB stick can be programmed like most ESP8266 board, i.e. via USB using the Arduino IDE. In case you wonder what kind of […]

VATek VMB8202D Enmoder SoC Supports DVB, ATSC, DTMB and ISDB Modulation, H.264 & MPEG-2 Encoding up to 1080p30

Terrestrial digital TV transmitters normally cost over 1,000 dollars because there are usually implemented with expensive FPGA chips, but Taiwan based VATek has designed a low cost chips such as VMB8202D Enmoder (aka B2 Enmoder) capable of encoding 1080p60 video input to MPEG-2  (1080p30 max) or H.264 (SD resolution max), and transmitting the resulting video over DVB-C, DVB-T, ATSC, DTMB, or ISDB-T standards. VATek B2 Enmoder SoC specifications: CPU – 32-bit RISC @ 400MHz Memory – Built-in DDR Modulation Engine – VATek Multi-standard Modulator 1.0 ATSC / DTMB / DVB-T / DVB-C Media Encoder – VATek Ultral Low Latency HD Encoder supporting 1080p30 or SD MPEG-2 and SD H.264 encoding Audio Formats – MPEG-1 Layer 2, AAC Raw Video Inputs – 1x ITU-R BT.1120 or 2x ITU-R BT.656 up to 74.25MHz pixel clock Raw Audio Inputs – I2S up to 48kHz sample rate Stream Input Interface – Ethernet,  Transport Serial […]

The First Devices and Routers with WiFi 802.11ad Delivering Up 7Gbit/s Transfer Rates at 60 GHz Will Be Available This Year

802.11ad is the latest and fastest WiFi standard working in the 60 GHz band and delivering up to 7 Gbit per second data transmission rates. The 60 GHz  frequency band offers both advantages and disadvantages because it does not penetrate through walls nor water, meaning it can only be used within a room limiting the range, but at the same time it’s more secure since it cannot be snooped from the outside, and for people who worry about health effects it does not penetrate the human body. 802.11ad routers will also be able to switch to 2.4 and 5.0 GHz frequency bands in order to go through walls. The table above nicely summarize the key features of 802.11ad over 802.11ac and 802.11n, however the throughput row shows the theoretical maximum throughput, but in practice, using 802.11ac as example, clients are often limited to 433 or 866 Mbps, and distance and […]
