MikroElektronika Stepper 18 Click
Overview
Stepper 18 Click shield has a TI DRV426 stepper driver accessed via GPIO. It also features a Microchip MCP4726 DAC to allow for current control. The micro-step pins are controlled via physical switches, making them unavailable in Zephyr. The DRV8426 uses the work-queue timing source by default.
Note that the MCP4726 is compatible with the MCP4725 driver.
More information about the shield can be found at Mikroe Stepper 18 click [1].
