This makes OLinuXino perfect choice for home automation board. With the low power of only 2W A20-OLinuXino can run 24/7 consuming less than 1% of what desktop x86 server would take as power consumption.Īnother advantage is that with the build-in Lipo charger simple LiPo battery can run the OLinuXino for hours if the mains power supply fail, so no need for expensive server UPS. What makes A20-OLinuXino more flexible than your computer is that it have lot of additional hardware resources which you don’t have on your desktop computer – like GPIO ports, I2C, SPI, UARTs etc. It consumes only 2W of energy but runs Debian Wheezy and basically with it you can do anything you can do with your desktop Linux server/machine. There will be practical demonstrations and will be shared know-how captured for the 23+ years of experience with electronics manufacturing which cost gold 🙂Ī20-OLinuXino is Open Source Hardware Linux computer.

Third Workshop will be about SMT technology, type of components, how to design PCBs for SMT, what is solder paste, how to handle solder paste, how to design stencil for solder paste, how to print solder paste, reflow profiles, how to make profile and how to trouble shoot problems with SMT technology like printing, soldering etc. Second Workshop will present ESP8266 and RT5350 OSHW boards for IoT applications. Minnowboard MAX will be compared to OLinuXino and RK3188-SOM-EVB in terms of productivity, power consumption, Linux support, etc.

Update your agenda: Starting from 14.00 o’clock on 10th of January in Olimex Training Building there will be three interesting workshops.įirst Workshop will be about Intel vs ARM. It was good surprise to see that actual consumption is less, maybe the HDD enters stand-by mode when not used?Ģ014 is almost gone, New Year is coming and we will start the year with three Workshops on January 10th. We know that with 6600mAh battery the LIME will last at least 10 hours as it uses 1.5-2W, but the HDD is rated 5W (5V/1A), so we were expecting less time stand alone operation. We came today and sure we found all x86 servers down, but to our surprise the LIME with the HDD was working fine all these 6 hours of power blackout and didn’t shut down! Yesterday our power supply provider EVN warned us that they will change mains high voltage cables in our area and Olimex will have power supply cut from 9.00 to 15.00, so we had to take day off. This configuration works well several years already. To keep it as low power as possible we setup one A20-LIME + HDD320GB + 6600mAh LiPo battery. We decided to make separate server for this due to security reasons, we just wanted to keep our local network private and to allow external access only to this isolated server which we access also from outside like other users.
Initially we kept our all Olinuxino Linux images on Gdrive, but there were few issues with this, the images grew to many Gigabytes, and Gdrive start to restrict the access to the files after some limits were reach, so we decided to host these images by us on torrent. This UPS has lead-acid batteries inside which has to be changed every 3 years and cost almost as much as the UPS itself. To keep the servers alive during power downs, we had to buy expensive 2000 EUR UPS, which actually keep them no more than 20-30 minutes up when power is down, so basically just to allow you 10-15 minutes to finish your work and then to shut them down properly before the battery is drained. We are located in industrial area and power supply glitches are not uncommon, specially during the winter. They are quite power hungry as lot of HDDs are connected to them in RAID mirrors to prevent data loss. We have server rack with several x86 servers running Linux with our work file repositories, the ERP and etc.
