FireWRT and WiTi router boards based on Mediatek MT7621A processor offer lots of high speed interfaces with multiple Gigabit Ethernet ports, SATA connectors, and USB 3.0 ports, as well as 802.11ac connectivity for $70 to $80. Sadly FireWRT development was canceled once the company realized they could not get the Mediatek SoC at the right price, and while WiTi router has not been shipped to backers just yet. An even more powerful solution, which should cost $100 and up, is now in development with Turris Omnia board powered by Marvell ARMADA 385 dual core ARMv7 processor, and made in the Czech Republic. Turris Omnia board specifications: Processor – Marvell ARMADA 385 (88F6820?) dual core ARMv7 processor (Cortex A9 class) @ 1.6 GHz with 1MB L2 cache System Memory – Up to 1GB DDR3 Storage – 4GB flash, mSATA slot Connectivity 5x Gigabit Ethernet LAN ports 1x Gigabit Ethernet WAN port […]
BeagleBoard-X15 Board Based on TI Sitara AM5728 SoC Announced, To Sell for $239
We’ve first found out about Beagleboard-X15 open source hardware board about a year ago, and development has taken a bit longer than expected, but Beagleboard.org has now formally launched BeagleBoard-X15, which remains based on Texas Instruments Sitara AM5728 dual Cortex A15 processor, and is expected to ship before Christmas for $239. The key part of the specifications are still the same as last year, but we’ve got a few more details now: SoC – Texas Instruments Sitara AM5728 with: Two ARM Cortex A15 cores @ 1.5 GHz PowerVR SGX544-MP2 3D GPU, Vivante GC320 2D GPU Two Cortex M4 cores @ 212 MHz Dual core C66x DSP @ 700 MHz IVA (Image and Video Accelerator) for 1080p video decode (H.264, VC-1, MPEG 1/2/4, AVS, etc..) Four 32-bit PRUs (Programmable Real-time Units) System Memory – 2GB DDR3L @ 533MHz Storage – 4GB 8-bit eMMC flash, micro SD slot, and eSATA interface (500 […]
Linux Quick Start Guide for Roseapple Pi Board based on Actions Semi S500 Processor
Roseapple Pi is a development board powered by Actions Semi S500 processor with 2GB RAM, a USB 3.0 port and more, that is based on Actions Semi Bubblegum-S500 reference design also used by Lemon Pi board. The team behind the project sent me an early sample to try it out. I’ll take some pictures, before explaining how to install and setup Debian 8.1, and how to build and run your own minimal image from source. These instructions should also work for Lemon Pi and LeMaker Guitar boards. Roseapple Pi Photos I received the board in a bubble envelope with a thank you letter, and the board itself in an anti-static bag. No other accessories were provided. Ports, connectors, and headers from top left counter-clockwise: 4-pin UART console, two USB 2.0 ports, one USB 3.0 port, 10/100 Ethernet, a 40-pin Raspberry Pi comptabile header, a MIPI DSI connected, a micro USB […]
How to Reduce SD Card Firmware Images Download Size
So I’ve just received a Roseapple Pi board, and I finally managed to download Debian and Android images from Roseapple pi download page. It took me nearly 24 hours to be successful, as the Debian 8.1 image is nearly 2GB large and neither download links from Google Drive nor Baidu were reliable, so I had to try a few times, and after several failed attempt it work (morning is usually better). One way is to use better servers like Mega, at least in my experience, but another way to reduce download time and possibly bandwidth costs is to provide a smaller image, in this case not a minimal image, but an image with the same exact files and functionalities, but optimized for compression. I followed three main steps to reduce the firmware size from 2GB to 1.5GB in a computer running Ubuntu 14.04, but other Linux operating systems should also […]
PicoZed SDR (Software Defined Radio) System-on-Module Supports 70 MHz to 6.0 GHz Frequency Bands
PicoZed SoM based on Xilinx Zynq-7000 series SoCs was introduced in 2014 by Avnet. The company has now introduced a new version specifically designed for software designed radios which combines Zynq-7035 SoC with Analog Devices AD9361 RF transceiver supporting 70 MHz to 6.0 GHz frequency bands. Target applications include portable agile wireless communications, P25 public safety Radio, point-to-point communication, femtocell & picocell base stations and portable instrumentation. PicoZed SDR SoM specifications: SoC – Xilinx Zynq XC7Z035-2L FBG676I AP SoC with a dual core Cortex A9 processor @ 800 MHz and Kintex-7 FPGA with 275K logic cells System Memory – 1GB DDR3L SDRAM Storage – 256Mb QSPI Flash, microSD Card Interface Network Connectivity – 10/100/1000 Ethernet PHY USB – USB 2.0 OTG ULPI PHY I/Os – 205+ User I/O + 4 GTX channels Radio Transceiver – Analog Devices AD9361-BBCZ integrated RF Agile Transceiver with: 2 × 2 RF transceiver with integrated […]
LeMedia is a Linux Distribution based on Debian and Kodi 15.2 for Actions Semi S500 Processor
LeMaker has recently released LeMedia, a Linux distribution based on Kodi 15.2 and Debian Jessie for their Guitar board powered by Actions Semi S500 quad core Cortex A9 processor, also found in Lemon Pi, ActDuino-S500 and Roseapple Pi boards. The good news is that H.264 and MPEG4 hardware video decoding is implemented, as well as PowerVR SGX544 GPU 3D acceleration. This is an early version and while IR receiver, WiFi, HDMI and LCD output, and audio are working, the company explained that HDMI support may be flaky, USB 3.0 speed is not optimal, and touchscreen support had to be disabled. They also included a “LeMedia Settings” in the image to have a similar experience as “RaspBMC Settings”. The images for booting from SD card or eMMC can be downloaded here. It’s quite likely they only work on LeMaker Guitar board, and I could not find the Linux 3.10.37 kernel, nor […]

Weightless Development Kits are Finally Available (Sort of)
The first version of the Weightless standard aiming at lowering cost of IoT communications was published in 2013, but so far development kits were nowhere to be found. Nwave has now launched a Weightless-N SDK using sub-GHz spectrum, but not the white space spectrum used by Weightless-W, probably due to regulatory hurdles. Specifications and features of Nwave development board: MCU – Silicon Labs EFM32G210F128 ARM Cortex M3 MCU @ 32 MHz with 128KB flash, 16KB SRAM Connectivity – RM3 radio module (868MHz) and antenna connector (X3) USB – X1 USB port for connection to PC or UART interface, X2 micro USB port Debugging – UART, and 10-pin JTAG connector (X4) Expansion header – 16 through holes for GND, 3.3V, GPIOs, ADC, Timers output, I2C, etc… (X5) Misc – Three Jumpers for UART and other selections (TBD), reset buttons for USB ports?
