Tiny Arduino Leonardo Compatible Board, micro-USB, microSD, UEXT

Description

The OLIMEXINO-NANO is a tiny board with an Atmel ATmega32U4 AVR microcontroller which is loaded with Arduino Leonardo firmware. It can be programmed via a micro-USB cable in the same way as the standard
Arduino Leonardo
, and features both a microSD card slot (on the bottom side) and a UEXT connector in addition to a proprietary miniature shield interface.
The miniature shield interface allows you to plug in and stack mini shields in the same way you would on a full-sized Arduino with full-sized shields. You can see compatible mini shields in the
Optional Recommended Products
list below.
The UEXT connector allows you to add another peripheral module easily. The UEXT can provide I2C, RS232, SPI and power to the external device. There are dozens of UEXT modules available. Please see the
UEXT Boards Category
for a full list.

Stacking Shields
The following picture shows this OLIMEXINO-NANO with the
OLIMEXINO-NANO-BB
(Breadboard Connector Shield) on it, then the (Battery Shield) stacked onto the Breadboard Connector Shield. The Breadboard Connector Shield is then plugged into a

Instead of being tethered to a PC, you can use the
TOL-11456
(1A) or
WA-USB-2A
wall-mount supplies which use a USB cable for power delivery. The optional OLIMEXINO-NANO Battery Shield gives you a choice between using a coin cell battery or a LiPo battery, or even a barrel jack adapter for that shield's JST connector. The shield, batteries and adapters can be selected in the
Optional Recommended Products
list below. Just remember that the batteries and the JST adapters can't be used directly on this board; they require the Battery Shield which also is in the list.
