The design goal was to build a fairly simple device which allows to digitize signals with frequencies ranging from DC to around 1MHz with very long sampling buffer (i.e. millions of points).
Features:Very simple hardware design; most functionality provided by software.
Two 8-bit channels, each configurable as 8bit analog input or 8 digital inputs.
Sampling rate: Tunable in 8 steps from 50kS/s to 10MS/s.

Live transmission of data stream allows storage of nearly unlimited number of samples.
Analog input sensitivity: 1Vpp or 2Vpp, DC coupled with 2.5V common mode.
Digital input: Schmitt trigger, 3.3V or 5V CMOS levels.
USB-powered operation.
