2) Compact, cost effective format based on 48MIPs microprocessor with native USB and serial interface

3) Temperature compensated focusing

4) Stepping rates based on resolution of 0.68ms timer, up to 1464 PPS

5) Wave stepping, Half stepping and full torque step types

6) Field upgradeable firmware, customizations considered

7) No requirements on phase winding pinouts, firmware natively supports all possible phase wiring configurations

8) Coming soon: support on MAC by Starklabs focuser control software
