Arduino Pro Mini 5V with Free Header pins

Arduino Pro Mini is a compact yet powerful Arduino development Board. It works on the same ATmega328 microcontroller like UNO but is the only 1/3rd of the size of UNO. The size is reduced by removing an in-built programmer and the USB port, so pro mini requires an external programmer like an FTDI board to program it. The small size enables the board to be used on a PCB and other final applications. Apart from the size, the specification of pro mini (5V) and UNO are almost similar and hence they both can exchange the same program. Note: This version of Pro mini is 5V Specifications Features Microcontroller: Atmega328p – 8 BIT AVR controller Operating Voltage: 5V Raw Voltage input: 5V to 12V Maximum current through each I/O pin: 40mA Maximum total current drawn from the chip: 200mA Flash Memory: 32Kbytes EEPROM: 1Kbyte Internal RAM: 2Kbytes Clock Frequency: 16 MHz Operating Temperature: -40ºC to 105ºC Supports auto-reset On-board Power and Status LEDs Analog Pins: 8 Digital I/Os: 14 Package Includes 1 x Pro Mini ATMEGA328P 5V/16MHz
