Top16 USB IO module
Generic interface to output devices such as relays, solenoids, strikes, low voltage lamps, unipolar stepper motors.
Read inputs from sensors and switches.
8 X Current sinking (switch to ground) outputs, 250mA to 30 Volts
Individual PWM control on all outputs
8 X Simultaneous Digital (0 to 30 V) and Analog Inputs (0 to 5 Volt single-ended 12 bit)
USB powered

libftdi is an open source staticlly linked interface to the ftdi chip.
this can be used in OS's not compatible with the D2XX shared lirary (For example it works on Debian). Source code and example using liftdi version 1.0
Stepper Motor Control
The outputs of the top16 can drive unipolar stepper motors at speeds up to 50Hz
C example using Jaycar YM-2751
