BITalino (r)evolution enables the synchronous and simultaneous acquisition of up to 6 analog (A1-A6), 2 digital inputs (I1 & I2) and 2 digital outputs (O1 & O2). When the channels are all used simultaneously, 4 of the 6-analog channels are operating at 10-bit and the other 2 channels at 6-bit resolution.
Note also that you can always synchronize multiple BITalinos (up to 3), enabling you to expand the number of channels. Provided that they have digital ports connected between them you’ll be able to have a common time reference from which to synchronize the data from each device.
