Questions answered in these manuals
What is the STEVAL-IPC003V1 adapter board used for?
It is designed for a connectivity line demonstration board to print parking tickets and generate text messages received over ethernet.
Which board is this adapter compatible with?
It is a daughter board for the STM3210C_EVAL.
Can these ICs drive unipolar motors?
No, the document states that a single package drives a 2-phase bipolar stepper motor, challenging the assumption that unipolar motors are easier to drive.
