From the project

NXP PCA9629A I2C stepper motor controller breakout board designed in KiCAD

- NXP PCA9629A I²C Stepper Controller - Allegro A3909 Dual Full Bridge Motor Driver - Maxim Integrated MAX17291 5.5V Boost Converter powering the controller and motor (can be deselected through a jumper to power a motor up to 18V)

- ## ToDo - Boost converter is very weak. Replace for another with higher current.
