AVR Mini & Mini Lite Microcontroller Boards

Arduino.org AVR Mini and Mini Lite Microcontroller Boards are small boards based on the ATmega328 microcontroller and are intended for use on breadboards and where space is at a premium. Arduino AVR Mini and Mini Lite Microcontroller Boards each have 14 digital input/output pins (of which 6 can be used as PWM outputs), 8 analog inputs, and a 16 MHz crystal oscillator. They can be programmed with the USB, the mini USB adapter, or RS232-to-TTL serial adapters.

Please note that the newest versions of the Mini and Mini Lite are shipping with the Atmel ATmega328 rather than the ATmega168 as shown in the datasheet. Both microcontrollers are the same except for double the memory size on the ATmega328.

Mini USB Adapters

Arduino.org Mini USB Adapters convert USB connections into 5V TX and RX that can be connected straight to the Arduino Mini or other microcontrollers, allowing them to talk to the computer. Arduino Mini USB Adapters are based on the FT232RL chip from FTDI (drivers are included with the Arduino software).
