Arduino Leonardo AVR Development Board Arduino Leonardo AVR Development Board is a microcontroller board based on the Atmel ATmega32u4. It offers 20 digital IOs (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button. The Arduino Leonardo differs from all preceding boards in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Leonardo to appear to a connected computer as an HID, such as a mouse or keyboard, in addition to a virtual (CDC) serial / COM port. The Leonardo board contains everything needed to support the microcontroller. Simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter... Less

Each relay is protected by a fuse. Granted, the fuse is hard-soldered to the board; so if you blow the fuse, you'll have to de-solder and re-solder a new fuse in place, but that's not a huge problem. Protects each circuit from drawing more than the 2 amps that the relay is rated for.The signal from the Arduino doesn't cut on the relay directly. Instead, the signal from the Arduino turns on a transistor, which closes a circuit that turns on the relay. The relay itself is optocoupled; so there is plenty of electrical isolation between the Arduino board and the relay. No worries at all on my part about frying my Arduino board.Each relay draws about 10 milliamps from the Arduino when switched on. If you're only turning on a few relays at the time, that is not a problem for the Arduino to... Less

The Arduino Mini is a small microcontroller board intended for use on breadboards and when space is at a premium. The revision 05 has a new package for the ATmega328 (datasheet), which enables all components to be on the top of the board. It also has an onboard reset button. The 05 version has the same pin configuration as revision 04. Additional features coming with the 05 version are: new PCB layout and design onboard reset button The Arduino Mini has 14 digital input/output pins (of which 6 can be used as PWM outputs), 8 analog inputs, and a 16 MHz crystal oscillator. It can be programmed with the USB Serial adapter or other USB or RS232 to TTL serial adapter. This product is sold with the pre-soldered pin headers on the two long sides.
