STEP400/800

Overview

STEP400/800 is a multi-axis stepper motor driver which can control via Ethernet. The current firmware is based on Open Sound Control protocol. Arduino Zero and official Ethernet library compatible. Stepper driver chips of STEP400 are STMicroelectronics's powerSTEP01, and STEP800's are L6470 which provide most of functionalities as a stepper driver. If you take a look at these datasheets, it will be easier to understand the functions and commands.
