ADuC-IO7020 DEVELOPMENT BOARD FOR ADuC7020
ARM7 MICROCONTROLLER
INFO:
ADuC-IO7020 is very good platform for automation application which need fast
ADC and DACs and need to commutate high loads. It have 4 relays 240VAC/10A,
4 optoisolated inputs, RS232, JTAG and the 1Msps ADC/DACs are available on separate
conenctor for connection to external sensors.
