C Real Time Clock NOISE IMMUNE design the LEDs and the BUTTONS are on the edge of the board so there is easy access even if the boards have shields on them all components are LOWER than the connectors so the shields do not interference with them mini USB connector is used which is common and used in most cell phones so you do not have to buy other cables Page 5 of 29 OLIMEXO 2012 OLIMEXINO 32U4 User s Manual Original design had flaw and the connectors were not spaced at 0 1 this make perfo board use impossible to keep the compatibility we have same spacing but we add next to this connector on 0 1 which customer can use with perforated boards All signals on the connectors are printed on top and on bottom of the board so when you check with probe you know exactly which port you are measuring 4 mount holes make board attachment easier 1 2 Similar boards OLIMEXINO 32U4 is ARDUINO LEONARDO like board with ATMega32UA It is a powerful board considering its low price but yet a starter board for the Arduino family The more powerful Arduino board we have in the range is OLIMEXINO 328 based on Arduino Duenomilanove It has a more sophisticated supply circuit USB OTG connector and there are more Arduino projects available 1 3 Organization Each section in this document covers a separate topic organized as follow Chapter 1 is an overview of the board usage and features Chapter 2 has a short introduction to
