The PiBot Opto-Isolated Relay Module is a great way to switch outputs like coolant, mist, or a VFD to turn on a spindle with the Pibot controller. This board is super easy to use and features 3 opto-isolated relays to minimize electrical interference.

The PiBot stepper motor driver module is an excellent choice for driving our Nema23 stepper motors. With a maximum current output of 4.12A-4.5A, it can handle even the high-powered Nema23 motors. The driver chip in these modules is the genuine Toshiba TB6600HG, designed for high-performance control of stepper motors. This ensures that your motor will function smoothly and precisely.
