Arduino Mini Pinout and Specification

The Arduino Mini is one of the smallest boards in the Arduino family and is based on the ATmega328P operating at 16 MHz. It has 32 Kbytes of Flash, 2 Kbytes of SRAM and 1 Kbytes EEPROM. Despite its small form factor, Arduino Mini Pinout includes 14 digital I/O pins, 8 analog inputs and 6 PWMs. It supports TWI (I2C), SPI, UART and 10-bit ADC. As shown in Arduino Mini Pinout, it doesn't have any connector. This means that an external USB to serial adapter is needed to program it.
