If people have ideas they would like to see incorporated, now is the time to speak.
All input opto's must accept the 3.3 Volt TTL standard.
All outputs should be suitable for driving both the 3.3 Volt and 5 Volt TTL standards.
Don't put opto's on the step and direction outputs or if you do then provide a bypass connection.
That's all I can think of at present.
