$59 HiFive1 Arduino Compatible Board is Powered by Sifive Open Source RISC-V MCU (Crowdfunding)

Royalty-free RISC-V instruction sets has been getting in the news in the last few years with various MMU designs from companies or projects like lowRISC, PULPino, and SiFive, and recently there are been rumors that Samsung may use RISC-V in their future IoT SoCs. Many projects are still in progress, and while you can get involved in OnChip Open-V MCU crowdfunding campaign to their get the MCU or a development board, the cost for the MCU ($49) and development board ($99) is a little on the high side, and delivery is expected in 2018 for most rewards. SiFive appears to have a more interesting open source RISC-V solution with HiFive1 Arduino compatible board going for $59 and slated to ship between December 2016 and February 2017. HiFive1 development board specifications: MCU – SiFive Freedom E310 (FE310) 32-bit RV32IMAC processor @ up to 320+ MHz (1.61 DMIPS/MHz) Storage – 128 Mbit […]

$49 Dashbot Car Dashboard Assistant is Powered by C.H.I.P Pro Allwinner GR8 Module (Crowdfunding)

Most companies specializing in development boards may sell a few accessories for their boards, but usually leave product design to their customers. Next Thing Co. does that too, but the company also produces some products like PocketCHIP portable Linux computer & retro game console, and more recently Dashbot, a voice controller assistant for your car’s dashboard powered by CHIP Pro module. Dashbot hardware specifications: CPU Module – CHIP Pro with Allwinner GR8 ARM Cortex A8 processor @ 1.0 GHz, 512MB NAND flash, 256 DDR3 RAM, 802.11 b/g/n WiFi, Bluetooth 4.2 External Storage – micro SD slot Display – Red LED display Audio – 32-bit audio DSP for beamforming & noise suppression; fairfield audio pre-processor with 24-bit ADC; high fidelity MEMS microphone array (106 dB dynamic range) USB – 1x USB host port Power Supply – 5V via USB port or 12V via power port (aka cigarette lighter) + backup LiFePo4 […]

GR-LoRa is a Reverse-Engineered Open Source Implementation of LoRa PHY

LPWAN standards such as LoRa or Sigfox allow you to transmit data over long distance, at ultra low power (up to 10 years on a AA battery), and for free if your use your own network (P2P or gateway), or a few dollars per years if you go through a network provider. The low cost is possible since those standards rely on 900 MHz ISM bands, meaning nobody has to pay millions of dollars to the government to obtain a license fee. Matt Knight looked at LoRa, and while Level 2 and 3 of the protocol (LoRaWan) has public documentation, Level 1 (LoRa PHY) is proprietary and the standard is proprietary. So he decided to reverse-engineer LoRa PHY using Microchip RN2903 based LoRa Technology Mote and Ettus B210 USB software defined radio, and software packages and tools such as Python and GNU Radio to successfully deliver GR-LoRa open source “GNU Radio […]

C.H.I.P Board and Allwinner A13/R8 SoCs To Get VPU Support in Linux Mainline

Allwinner has mixed relationships with open source communities such as Kodi, especially due to issues with its closed-source CedarX VPU drivers, and some GPL violations. However to address the former, linux-sunxi community has been working on open source Cedrus library for the video processor unit on Allwinner processors, that’s been successfully tested on boards such as Orange Pi One. Free Electrons has gone further, as they’ve made sure Cedrus now works with Linux mainline kernel, currently Linux 4.8, and tested it on Allwinner R8 based Pocket CHIP. The work has been done by Florent Revest, a 19 years old intern at the company, who delivered a new sunxi-cedrus driver, a Video4Linux (V4L2) memory-to-memory decoder kernel driver, and corresponding VA-API backend, with the implementations currently available on Github here and there respectively. Currently only MPEG2 and MPEG4 are working, but adding other codecs such as H.264, and video encoding is possible […]
