Arduino Pro Mini
The Arduino Pro Mini is a small yet powerful Arduino. The Pro Mini is based on the well-known ATmega328 in SMD version, the mini has no USB interface for programming but needs to be programmed serially, this makes the Pro Mini a lot smaller but no less powerful.
Because the Mini is so small, this board is suitable for use in very small places or spaces.
The Arduino Pro Mini is also suitable for use with a wide range of shields, however, to use a shield you need to make a header board yourself, or connect the Mini via module wires. Many modules such as a SPI RGB Display module or a 2 x 16 Character LCD module can be connected directly to the mini.
Despite the fact that the mini has no USB port, the mini is certainly not a lesser version than the Arduino Uno R3, the chip is exactly the same and therefore has the same possibilities as its bigger brother, the size on the other hand makes the mini so special.
The Specifications of the Arduino Pro Mini are as follows:
