ATMEGA128 is an AVR microcontroller from Atmel featuring 128K Flash, 4K RAM, 53 I/O lines arranged in seven 8 bit ports, 8 ADCs, 2 UARTs, 4 timers, 8 interrupts and much more.
ATMEGA128 Development Board brings out all the port pins of the microcontroller in neat PORT wise configuration. It is made from double sided reliable PTH PCB board .. Board can work on 7 to 15V AC or DC supply. It has built-in bridge for reverse polarity protection.Onboard 7805 voltage regulator can supply 1Amp current continuously without getting over heated. It has switches for boot loading, reset and power. It also has RS232 interface with DB9 female connector based on MAX232. All the ports are connected to standard berg pins & ISP programming FRC connector is provided to connect an AVR Dude.
Microcontroller: ATMEGA128 with 14.7456 MHz crystal (Also supports ATMEGA64)
Double side high quality PTH PCB for added strength.
Power: 7 to 15V, AC or DC, Heat sink on 7805 for better current rating
