    AutomataKit Stepper17 Circuit Design

    schematic

    routing

    The circuit uses an ATXmega256A3U microcontroller and a TMC2130 step driver to do the business. Between the two are an SPI bus, to configure the driver, two diagnosis lines, a step, direction, and enable lines.

    The TMC2130 is a popular step driver, and can sink ~ 1.5A of current.

    Power is bussed into the board with two M3 Screw Terminals. The board is not polarity protected. Data is delivered on an Automatakit Port, which includes a data line (uart TX / RX) and clock lines (CLKIN and CLKOUT)
