Frequently asked questions
Can I control it directly from an Arduino or ESP32?
The inputs are listed as TTL/CMOS compatible, so a microcontroller GPIO can drive them. Check the input logic thresholds in the datasheet and use a separate 8V to 32V supply for the motor.
Do I need external flyback diodes for the motor?
The listing states that clamp diodes are built into the output, so external flyback diodes are usually not required. A local decoupling capacitor on the motor supply is still recommended.
