Rockchip RK3288 Android 4.4.2 SDK and Schematics Released for Firefly Board

Firefly-RK3288 development board was first announced in July. I still don’t have news about availability nor pricing, but the T-Firefly website launched yesterday. They seem do have a nice Wiki, but unfortunately everything is currently in Chinese, except when you go to the download page. You’ll find firmware upgrade_tool for Linux and Windows, the USB drivers for rooting and firmware update, firmware images (Android 4.4.2, Ubuntu 14.04, and dual boot), the board schematics (PDF), and Android KitKat 4.4.2 SDK with U-Boot, Linux, and Android source code, some documentation, XBMC apk (no source) with H.265 hardware decode support for MP4, MOV and MKV container formats. The SDK is available on Bitbucket. I planned to test it, but unfortunately my network connection is very slow (and unstable) to this server, and I failed to retrieve it with git clone. The company also posted the build instructions in Chinese in their website, but […]

xWifi Open Source Hardware Wi-Fi Module and Dock for the Internet of Things (Crowdfunding)

For some reasons, Wi-Fi modules are pretty popular this year. After modules such as VoCore, AsiaRF AWM002, and ESP8622, here’s come xWifi. This module is based on Mediatek MT7681 SoC which includes a TCP/IP stack like Espressif ESP8622 or TI CC3300, so it won’t run OpenWRT like VoCore or AsiaRF modules. The module only consumes about 350mW during transfer, it will be open source hardware, and the xWifi module plus a dock with a 10A relay, a humidity and temperature sensor, and a LED will go for as low as $17. xWifi module only specifications: SoC – Mediatek MT7681 802.11 b/g/n SoC with 32-bit RISC CPU. Support for Client/softAP mode. Package size 5×5 mm Storage – 512KB SPI Flash (for firmware) I/Os via headers: UART and SPI interfaces. 5x GPIOs PWM Power – 3.3V, GND Power Consumption – ~70mA @ 5V (during RX active) Dimensions – 14 x 17 mm The […]

MinnowBoard MAX Schematics, Board layout, Gerber, and BoM Released

MinnowBoard MAX (aka MinnowBoard2) is an embedded board powered by Intel Atom Bay-Trail-I E3815 (single core) or E3825 (dual core) processor, with 1 to 2GB RAM, SATA II, USB 3.0, Gigabit Ethernet ports, and more. The board currently officially supports four operating systems: Debian GNU/Linux, Linux built with the Yocto Project, Android 4.4, and Windows 8.1. One of its main selling point is the price as the single core version sells for $99, and the dual core version for $129, rivalling in price with equivalent ARM based development boards. It’s also an open source hardware board, and as it’s now about to ship, CircuitCo released all hardware files under a Creative Commons CC-BY-SA license, allowing anybody with the right skills to create a clone, or their own hardware. Here are the files that have been released: Schematic (PDF) Schematic (Orcad DSN) Board Layout (Allegro BRD) Gerbers Bill of Materials Schematics […]

MIPS Creator CI20 Development Board Formally Announced, Free to Selected Developers

Earlier this month, I discovered MIPS Creator CI20 development board based on Ingenic JZ4780 dual core MIPS processor thanks to one of my reader. Imagination Technologies has now launched the board, which will run Debian 7 first, soon support Android 4.4 and others Linux distributions, and the company places their MIPS board as a competitor to the popular ARM based boards such as the Raspberry Pi and BeagleBone Black. This is the first board part of Prpl initiative for open source Linux and Android software for the MIPS architecture. As a reminder, I’ll list the hardware specifications again: SoC – Ingenic JZ4780 dual core MIPS32 processor @ 1.2 GHz with Imagination PowerVR SGX540 GPU. 32kI + 32kD per core, 512K shared L2. System Memory – 1GB DDR3 Storage – 8GB NOR flash, 1x SD card slot, 1x SD card slot via expansion Video Output – HDMI up to 1080p Audio […]

Interview with Allwinner Regarding their Linaro Membership

Since Allwinner has joined the Linaro Digital Home Group earlier this year, many people, including myself, have wondered what it means in terms of Linux support, and the engagement with the open source community. Following up on an idea from a regular reader, I’ve decided to asked a few questions to Ben-El Baz, marketing manager at Allwinner, and Linaro contact for Allwinner, which he kindly answered, and accepted to be published on CNX Software. CNXSoft: Why did Allwinner decide to join Linaro, and especially the Digital Home Group? Allwinner: One of our company’s goals is to be a technology leader. It’s ambitious but not too far-fetched given the background of our leadership and engineering team. There’s an extremely talented group of guys behind the scenes here! Leading is difficult unless you’re involved in collaborative organizations like Linaro that work on new technology. Joining Linaro is an opportunity for us to […]

Embedded Linux Conference Europe 2014 Schedule – IoT, ARM vs x86, Optimization, Power Management, Debugging…

The Embedded Linux Conference Europe (ELC 2014), CloudOpen, and LinuxCon Europe will jointly take place at the Congress Centre Düsseldorf, in Germany on October 13 – 15, 2014. The 3-day events will consists of keynotes, presentations, and tutorials. Each day will open with two or three keynotes by speakers including Jim Zemlin (Executive Director, Linux Foundation), and Jono Bacon (XPRIZE), followed by presentation and tutorials. There will be 45 presentations for ELCE, 58 for LinuxCon, and 47 for CloudOpen, I’ll make a virtual schedule with a few sessions part of the Embedded Linux Conference Europe “track”. Monday, October 13 11:15 – 12:05 – Performance Analysis Using the Perf Suite by Mans Rullgar, Consultant When faced with a performance problem, the initial steps towards a solution include identifying the sections of code responsible and the precise reasons they are time-consuming.

WRTNode is a Hacker-Friendly Open Source Hardware OpenWRT Wi-Fi Module Selling for $25

There are now some tiny and low cost ($15 to $20) Wi-Fi modules supporting OpenWRT such as VoCore and AsiaRF AWM002. However due to their small size they may not be that hacker’s friendly as they can’t have 2.54mm headers due to heir small size, and I’ve recently received AsiaRF AWM002 only to find out it not only needs 3.3V supply voltage, but also 1.8V and 1.2V. So I’d need to make my own power circuit with the required LDOs, or purchase a $20 base board to use the module. Here comes WRTnode another larger Wi-Fi module but with more usable 2.54mm headers, and based on the more powerful Mediatek MT7620N processor @ 600MHz. WRTnode hardware specifications: Processor – Mediatek MT7620N 600MHz MIPS CPU (MIPS24KEc) System Memory – 64MB DDR2 Storage – 16MB SPI flash Connectivity – Wi-Fi 2T2R 802.11n 2.4 GHz up to 300Mbps Expansion Headers – 2x with […]

Vigekwear is a Modularized, Open source, Wearable BLE Development Kit (Crowdfunding)

[Update: Atomwear has been renamed to Vigekwear due to (Intel’s) copyrights infringement]. Giayee is a company mainly manufacturing Android tablets, thin clients, and mini PCs, but their latest product, called Atomwear, is a Bluetooth Low Energy (BLE) development kit based on Nordic nRF51822 chipset that comes with various modules such as battery charger, accelerometer, gyroscope, OLED display, heart rate monitor, etc… which connect together via 24-pin connector on a standard rigid baseboard or a flexible printed circuit (FPC). All modules are connected via the same 24-pin connector with power, I2C, SPI, UART, ADC, and GPIOs signals. The baseboard and FPC both contain 6 such connectors connected in parallel for up to 6 modules, and two baseboard can be connected together via a bridge circuit to accept more modules. The minimum configuration is with a BLE MCU module, and a power module. The different boards and modules are listed as follows: […]
