Datasheet
INTRODUCT ION:
AVR-MT128 is simple but powerful board which uses the MCU ATMega128
from Atmel. With its LCD, buttons, relay and variety of interfaces such as
RS232 (in two variants – 4 pins and DB9), JTAG, ISCP, Dallas, etc. this
board is suitable for different embedded systems applications.
