Arduino Pro Mini Board
The Arduino Pro Mini is intended for semi-permanent installation in objects or exhibitions. The board comes without pre-mounted headers, allowing the use of various types of connectors or direct soldering of wires. The pin layout is compatible with the Arduino Mini.
There are two version of the Pro Mini. One runs at 3.3V and 8 MHz, the other at 5V and 16 MHz.
*Operating Voltage: 3.3V or 5V (depending on model)
*Input Voltage: 3.35 -12 V (3.3V model) or 5 - 12 V (5V model)
*Digital I/O Pins: 14 (of which 6 provide PWM output)
*Analog Input Pins: 8
*DC Current per I/O Pin: 40 mA
*Flash Memory: 16 KB (of which 2 KB used by bootloader)
*SRAM: 1 KB
*EEPROM: 512 bytes
*Clock Speed: 8 MHz (3.3V model) or 16 MHz (5V model)
