Areduino Serial + Atmega 8 is a basic board that uses RS232 as an interface to a computer for programming or communication. It has 14 digital inputoutput pins (out of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a DB9 connection, a power jack, an ICSP header, and a reset button. Areduino Serial + Atmega contains everything needed to support the microcontroller; simply connect it to a computer with a Serial cable and power it with a AC to DC adapter or battery to get started. Areduino Serial + Atmega board comes fully assembled and tested with ATmega8 pre-loaded with boot loader.
Detail:

• Comes with an ATmega8 with a pre loaded Arduino boot loader
• Auto reset feature
• Auto reset enabledisable jumper, to avoid not desired resetting
• Arduino Diecimila compatible reset pin
• Pin13 onboard led, with current limiter resistor
• TX and RX onboard led
• Jumper to disable serial communication and to enable RX external pull down resistor, to avoid “RX floating error”. This feature allows using digital pin 0 and pin1 as a normal pin, when serial communication is not needed
• 8 Kbytes Flash program memory
• 512 Bytes EEPROM
