The Olimex Olimexino-32U4 is an ATMEGA 32U4 based Arduino Leonardo compatible microcontroller board. Olimex have capitalised on and improved upon the Leonardo's design in a number of ways making this a very attractive alternative. Following Atmel's recommendations the power system has been reworked for noise immunity preventing spurious RESETs when the board drives motors.
The Olimex design uses ultra low-power voltage regulators drawing only a few microamps, opening the door to battery powered, hand held applications. The board's built-in Li-Po charger keeps batteries topped up when connected to an external supply. When the supply is removed the batteries automatically take over the load without user intervention. Li-Po batteries are available separately.
In order to make use of perforated boards or breadboards there are additional solder pads for all the IO signals to take header pins at 0.1in (2.54mm) pitch.
- LEDs are at the board edges for clarity
- All low profile components for clearance with shields
- Clear printed legend on the top side of the board
- UEXT connector for easy expansion (RF, ZigBee, GPS etc)
- Works with 3.3 or 5V DC shields
- 4 mounting holes
