Several Arduino boards have been designed to be as small as possible this year, including Microduino (25.40 x 27.94mm) and OLIMEXINO-NANO (30 x 30 mm). But Olimex has gone a step further, or should I say smaller, with OLIMEXINO-85S that just a little bit bigger than a micro SD card at 16.9 x 12.7 mm, and may currently claim the title of the smallest Arduino compatible board ever. A board that tiny comes with pretty short specifications: MCU – Atmel ATTiny85 @ 20MHz with 8 KB Flash, and 512B RAM. Misc – two LEDs one for power supply and one user programmable I/O – All 6 I/O pins (I2C, SPI, up to 4 ADC), as well as power pins, available via through holes Power – Via USB micro connector or by LiPo battery The board will be programmable by the Arduino IDE made by Digispark. OLIMEXINO-85S will be available at […]
Olimex Announces 30 Euros A10-OLinuXino-LIME Development Board for December
The Raspberry Pi, Beaglebone Black and Cubieboard are probably the best selling ARM Linux boards in the sub $50 category, but they’ll soon be joined by Olimex A10-OLinuXino-LIME powered by AllWinner A10 ARM Cortex A8 SoC with 512MB RAM that will sell for 30 Euros (About $40) when it becomes available in December. Another version of the board based on AllWinner A20 dual core Cortex A7 SoC, called A20-OLinuXino-LIME will also be sold, adding Gigabit Ethernet, and scheduled for Q1 2014. Pricing has yet to be disclosed for the A20 version. A10-OLinuXino-LIME specifications: SoC – AllWinner A10 ARM Cortex-A8 @ 1GHz with Mali-400 GPU System Memory – 512MB DDR3 Storage – microSD card slot, SATA, and optional 4GB NAND Flash Video Output – HDMI 1080p USB – USB-OTG + 2x USB Hosts Connectivity – 10/100Mbit Ethernet Expansions – 200 GPIOs on 0.05″ connectors Misc – Lipo battery management and connector, […]
Olimex Announces OLIMEXINO-NANO, a Tiny Arduino Leonardo Compatible Board
Last month, I wrote about Microduino, a tiny Arduino compatible board about the size of a coin. Olimex has also being working on their own tiny version of the Arduino board, OLIMEXINO-NANO, slightly larger than Microduino (30x30mm vs 25.4×27.94mm) but also featuring the UEXT connector which is an advantage if your own or plan to use UEXT expansion boards, but it could be an inconvenience if you don’t, as the connector is a little bulky. Here are the specs of the board: MCU – Atmel ATMega32U4 processor (Leonardo compatible) with 2.5KB RAM, 32KB flash memory, and 1KB EEPROM. Storage (external) – microSD card connector for data logging on SD-card USB – micro USB connector for programming and power supply when debugging Misc – RESET button, USER button, 2x status LEDs Expansion Connectors: UEXT connector for RF, Zigbee, Ethernet, RELAY, RGB LED, etc UEXT modules Connector 14 pin 0.05″ Connector 20 […]
Fedora 19 ARM Remix R1 Release With Support for AllWinner A10, A10s, A13 and A20 SoCs
After releasing a stable version of Fedora 18 for AllWinner A10 and A13 in February, Hans de Goede, working at Red Hat and a Fedora contributor, has recently announced “Fedora 19 ARM remix for Allwinner SOCs” on linux-sunxi community mailing list. This released based on Fedora 19 for ARM together with linux-sunxi kernel and u-boot, adds support for A10s and A20 based devices, and 38 boards and devices are now supported. To give it a try, download the 665MB image:
1 |
wget http://scotland.proximity.on.ca/contrib-images/hansg/Fedora-19-a10-armhfp-r1.img.xz |
then write it to an SD card (8GB or greater):
1 2 |
xzcat Fedora-19-a10-armhfp-r1.img.xz > /dev/[device] sync |
Where you have to replace [device] with your actual SD card device, e.g. sdc.Since u-boot is board/product specific, you’ll also have to update u-boot for your hardware. Remove the SD card, re-insert it, and run:<
1 |
sh <uboot-part-mount>/select-board.sh |
to display a graphical menu (if dialog is installed on your Linux PC), or a list supported boards and products:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 |

Open Source Prosthetic Arm Controlled By Muscle Movements
Gustavo Brancante is working on a very interesting project that let you control a prosthetic arm with your muscle movement using open source technology with InMoov Hand (which can be 3D printed), Arduino Uno R3, and Olimex Electrocardiography electromiography shield (SHIELD-EKG-EMG). This is called a Myo-Electric Prosthesis. Gabriel wrote a tutorial to use his “open arm” which I’ll summarize here. On the hardware front, you’ll also need a UDP compatible Wifi Shield configured as a UDP server with a fixed IP in the same LAN as the smartphone, and 57600 bps. TouchOSC (for smartphone and Workstation) is used with the following layout for calibration and feature selection. Finally load the program below to your Arduino board: Once everything is connected together, you should be able to do that: The demo looks impressive, but this is still work in progress, and next step will be to use a four channel EMG instead […]
Souliss Automation and IoT Framework Makes Your Home Smarter
Souliss is an open-source framework written in C/C++ for the Internet of Things and home automation that runs on Arduino boards, or other Atmel AVR MCU based boards, and let your control lighting, heating, or anything else you can think of via your Android device, or switches connected to your board(s). You can get started with Souliss in 3 steps: Getting the building blocks, for example: Arduino, Olimex, or other AVR boards (See list of supported boards) Relay boards ON/OFF Switches, Lights, etc… Wi-Fi router Download and load Souliss to an AVR powered board controlling real things such as lights. Monitor and/or control via Souliss Home Automation App for Android. A detailed getting started guide is provided on Souliss Google Code page. Internally, the framework is composed of three parts: Souliss, an application level layer, MaCaco, a communication protocol and vNet, a transport layer. I’ll skip details in this post, […]
Olimex A20-OLinuXino Prototype, AllWinner A20 SoM In The Work
Yesterday, Olimex showed their new A20-OLinuXino board. This AllWinner A20 board is still a prototype, and there are currently 3 of them only, but the good news is that it appears to be working, 50 developer edition boards will be manufactured shortly, and mass production should start in June. AllWinner A20 dual core Cortex A7 can clearly be seen in the middle of the board, but if you look close to the top left, you’ll see a marking: “A10-OLINUXINO-MICRO”. That’s because, as planned, they managed to design one PCB for both AllWinner A10 and A20 processors, and they’ll sell both versions. Olimex A10/A20-Olinuxino boards have the followings specifications: SoC – AllWinner A10 Cortex A8 processor or AllWinner A20 dual core Cortex A7 processor, both running @1Ghz System Memory – 512MB or 1GB DDR3 memory depending on model Storage – 4GB NAND Flash (optional), 2x microSD card slot, and SATA connector […]
AllWinner A20 Linux Source Code, EVB Schematics and Product Brief
Hardware based on AllWinner A20 such as Cloudsto Media PC PRO DRIVEDOCK, should start to be available soon, and resources for developers have been slowly released (or leaked) to the community. AllWinner A20 Source Code The source code for AllWinner A20 and A31 has been released to sunxi-linux a while back, and they have started to clean up the code before hardware becomes available. The code apparently hasn’t made it to sunxi-linux github account just yet, but Linux for A20 has been imported into github at https://github.com/amery/linux-allwinner/tree/import/lichee-3.3/a20-dev. AllWinner A20 is known as sun7i in the code. AllWinner A20 Evaluation Board Schematics and Product Brief Olimex received A20 EVB schematics and product brief from AllWinner earlier this week, and as usual, they promptly uploaded those documents to their github account. The 3-page product brief does not bring anything new, and the data sheet does not seem to be available right now. […]
