3.4 Further Use Cases: Two Bipolar Stepper Motors

This illustration presents a method for alternately operating two bipolar stepper motors with a solitary AVR microcontroller paired with dual power boards. The inclusion of a second motor serves to exemplify the capabilities of the PORTMUX peripheral. In this setup, the motors are engaged sequentially, not simultaneously.

The hardware used includes the AVR16EB32 Curiosity Nano Development board, in conjunction with the MPPB, the AVR EB CNANO to MPPB Adapter Board, a pair of stepper motors, and a power source. The configuration allows a single or dual power supply to energize both MPPBs.
