CHAPTER 1: OVERVIEW
1. Introduction to the chapter
Thank you for choosing the OLIMEXINO-85 from Olimex! This document provides a user’s guide
for OLIMEXINO-85. As an overview, this chapter gives the scope of this document and lists the
board’s features. The document’s organization is then detailed.
The OLIMEXINO-85 development board enables code development of applications running on the
AVR ATtiny85 microcontroller, manufactured by Atmel Corporation, USA.
OLIMEXINO-85 is an open-source, open-hardware project and all documentation is available to
the customer.
1.1 Features
The board has the following set of features (note about the difference between the two versions of
the board):
ATtiny85-PU microcontroller with pre-loaded "micronucleus tiny85" bootloader
Programmed via the USB type B connector
Tested and working with Digisparks's Arduino distribution
Breadbord compatible via the header
Two LEDs – user-programmable and power status
Reset button
All components already soldered (unlike the DIY version)
Easy-to-replace components in case of fault
Open-hardware board, board schematics and layout available for Eagle
Open-software board, thanks to the Digispark's community effort and the micronucleus
project

1.2 Target market and purpose of the board
All boards in the OLIMEXINO family feature a built-in bootloader (for serial programming without
special tools). The main usage of the boards is software embedded development without the urge of
understanding perfectly the hardware using Arduino or Arduino-derived IDE.
The strong points of the OLIMEXINO-85 are: the tiny form factor, the small consumption, the fact
that you can program it without special programmer via the USB cable.
Customers have full access to the technical documentation of the board. The software is released
under General Purpose License and the board is considered open-hardware – all schematics and
board design files are available to the customer under the Creative Commons Attribution-
ShareAlike 3.0 Unported License.
