Clean install of Arduino IDE for OLIMEXINO-85 boards


via Olimex Projects page

Paolo PerCdS posted new project how to make clean install of Arduino IDE and add OLIMEXINO-85 board in the IDE.


New Product in stock: World’s smallest Arduino ever 16.9 x 12.7 mm


OLIMEXINO-85S is smallest Arduino compatible board in the world with only 16.9 x 12.7 mm it’s with microSD card like size.

New Product in stock: OLIMEXINO-85BC


OLIMEXINO-85BC is new OLIMEXINO-85 derivate with same functionality but having additional LiPo charger on board, which makes it perfect for wearable apps, once you plug the USB cable to OLIMEXINO-85BC it will start to charge the LiPo battery attached then when you disconnect will continue to operate from the battery.

FOSDEM-85 as thermometer with no external components


Stefan Goetze submitted today cool project with FOSDEM-85 in our Project section.

He is using the ATTiny85 internal chip sensor to measure the temperature, which he displays with LED blinks on Pinguino eyes. For this purpose he re-connected the Power LED to another port.

The document where he explains how he build it together with all source codes is here

Now FOSDEM-85 can be used as thermometer on your desk 🙂

A20-ENC, OLIMEXINO-85-KIT and OLIMEXINO-85-ASM are in stock!


A20-ENC the plastic enclosure for A20-OLinuXino-MICRO is now in stock, the pictures on the web page show how to be assembled.

OLIMEXINO-85-KIT and OLIMEXINO-85-ASM are also in stock now. We still work on the assembly instruction and it will be ready and uploaded by the end of the day.

With OLIMEXINO-85-KIT we offer for very first time development board in KIT form. This is something new for us, it brings also new experience for the customer: to DO-IT-YOURSELF and to have the pleasure to see how something you build yourself start working.

I still do remember how proud I was when I was 12 and build my first radio and it worked! I hope you will have the same pleasant experience building your first Arduino with OLIMEXINO-85-KIT.

For the moment we use Digispark VID/PID and Arduino modified IDE, as this is the only out of the box working solution for ATTiny85. We have our own USB VID/PID and we are going to replace the Digispark one as soon as we figure out how to do this. If someone want to help on this we will have nice present for the efforts she/he will do 🙂

Look Mom I can shrink Arduino even more! And it cost only EUR 4.00!


On October 11 I blogged for our OLIMEXINO-NANO which is already in production and will be ready for sale on November 1st 🙂

With dimensions only 30×30 mm NANO is really cool, but we wanted to see if we can go smaller 😉

As you know on November 2 and 3rd there is OpenFest and we are partnering with the organizers and will make hardware hackathon where everyone who want to learn soldering to may build his own Arduino which to take with him. For this purpose we had to make some small but easy to solder board mostly with PTH components which are easy to solder for beginners.

This is how we made OLIMEXINO-85 you see above on the picture it’s only 30×20 mm and it’s made to make easy breadboarding:


For OpenFest we are preparing 100 kits of OLIMEXINO-85 which will contain all components, so everyone who want to try soldering can build his own Arduino with the kit.

OLIMEXINO-85 is build around the well known Little wire design same design is used also for Digispark and Adafruit’s Trinket.

All they use V-USB AVR emulation of USB with bit-banging and although ATTiny85 have no USB port it works as USB 1.1 device and have bootloader which can be tweaked to work with Arduino.

Unpleasant surprise for those who want to make the design is that on and the software they publish compile but missing right config words for the AVR which will obstracle people who want to DIY this design.

Digispark is the only board from the three above with proper sources and working HEX files and published pre-build Arduino IDE with ATTiny85 supported.

OLIMEXINO-85 (in kit form for DIY learning how to soldering) will be on our web tomorrow for sale with price EUR 4.00, which is probably lowest cost Arduino board on the market, for those who are lazy and do not want to solder the assembled and tested version will sells for EUR 6.00

We work on another version with only SMT components which have build-in Lipo battery charger and possibility to run on 3.3V and 5V named OLIMEXINO-85BC (battery – charger) this version will be perfect for wearable electronics and will be available in November the price is EUR 8.00 and will be offered only in assembled state.
