2.3 Powering the board

The usual way to power OLIMEXINO-85 would be to connect it to your computer via USB cable. 
The OLIMEXINO-85 has a USB type B connector (or mini USB connector, older revisions have 
the smaller one) mounted so make sure your cable is suitable.

The other way to power OLIMEXINO-85 – supply 2.7VDC to 5VDC to the VCC pin of the header.
Connect the supply's ground pin to the board's GND pin.

2.4 Connecting to the Arduino IDE

The ATtiny85 microcontroller of the OLIMEXINO-85 comes pre-programmed with a bootloader 
firmware. This firmware allows it to act as a USB device and new software can be uploaded by via 
a USB cable by a modified version of the Arduino IDE.

The OLIMEXINO-85 runs the “Micronucleus” bootloader, an open source community project. The 
project repository can be found here: 

https://github.com/micronucleus/micronucleus

This bootloader is also used by the Digispark board – the board that inspired OLIMEXINO-85. 
OLIMEXINO-85 uses the VID/PID pair that the creator of the Digispark – Digistump donated to 
the community.

For complete and latest instructions on how to use connect to Arduino IDE please visit:

http://digistump.com/wiki/digispark/tutorials/connecting

There are also good instructions on how to select the proper board so you can upload programs. It is
important that due to the small size of OLIMEXINO-85 it has a specific set of settings and a special
algorithm of uploading.

OLIMEXINO-85 is recognized as the default board that is selected by default after the installation 
of the Digistump support in the Arduino “Board Manager”. That is “Digispark (Default – 16.5mhz)”
under “Tools → Board”

When you have a program ready to upload you need to disconnect the board from the mini USB! 
Then press the upload button in the Arduino IDE interface and you will be asked to connect the 
board in the next 60 seconds. After you connect the OLIMEXINO-85 don't press anything and just 
wait until the code is uploaded!

2.5 Examples and libraries tested by OLIMEX

There are number of examples that show different applications of OLIMEXINO-85. They might be 
downloaded from the software section of the OLIMEXINO-85's own web-page here:
