Typical Application

>  AS-6408 have two output ways, one is 64CH <-> 8CH and one is 64 <-> 1CH, the 1CH output is after the 8CH output and they can working at the same time.

>  AS-6408 have onboard UNO CORE design , that means it can be working alone to process the 64CH input and read by A0 to A7 with 10bit ADC , and then sent data via TXD/RXD , if you using the RF UNO CORE it can be implement wireless data acquisition very easy.

>  The input signal level should not exceed VCC (Range of 0 to VCC), otherwise it may cause signal distortion.

>  The control signal is standard COMS TTL-3.3V level.
