Arduino Pro Micro
This is the smallest and the cheapest board from Arduino !!
Arduino, describes a set of boards that provide easy to use hardware and software that allows people to construct interactive projects using all manner of electronics. No prior knowledge is required to begin, tutorials and small projects exist to help introduce you to the vast features and possibilities that the board series offers. Before you know it you will be embarking on large and ambitious projects without any limits.
The main chip is the ATmega 32U4, the same 16MHz powerhouse found in the Leonardo. The 32U4 also contains an internal USB transceiver, so no drivers are required. With the micro USB port on this little guy, no FTDI board is required, just plug it into your PC.
This tiny little board does all of the neat-o Arduino tricks that youre familiar with: 4 channels of 10-bit ADC, 5 PWM pins, 12 DIOs as well as hardware serial connections Rx and Tx. Running at 16MHz and 5V, this board will remind you a lot of your other favorite Arduino-compatible boards but this little guy can go just about anywhere. There is a voltage regulator on board so it can accept voltage up to 12VDC. If you're supplying unregulated power to the board, be sure to connect to the 'RAW' pin and not VCC.
ATmega32U4 running at 5V/16MHz
Supported under Arduino IDE v1.0.1
Recommand power supply for board: 6-7V, less than 9V
On-Board micro-USB connector for programming
4 x 10-bit ADC pins
12 x Digital I/Os (5 are PWM capable)
Rx and Tx Hardware Serial Connections
the Smallest Arduino-Compatible Board Yet
Pro Micro Top Tips:
When programming the Pro Micro, it will show up as ‘Arduino Leonardo’ in the Arduino IDE and when selecting the type of board, you also need to select Leonardo.
There are two versions which you can buy – a 5V, 16 MHz version and a 3.3V, 8 MHz version. Unless you have a really good reason, I would always go for the 5V one.
Don’t get confused with the Pro Mini. a lot of people online confuse the Pro Micro (which has a USB connector) with the Pro Mini (doesn’t have a USB connector). Note the difference in the pictures below. When buying one, make sure to get a Pro Micro.
Reason 1) It can do everything an Uno can
Reason 2) It’s super cheap
Reason 3) It’s compact and breadboard friendly
Reason 4) You can embed it
Reason 5) It can act as a keyboard and a mouse
