The driver controller A4988 is compatible with our
Nema 17 and
Nema 14 motors. For the
Nema 23 motor we recommend the use of the model
DRV8825.
In addition, this small component includes:
• Compatible with almost all boards (
RAMPS, Sanguinololu, etc...)
• Overheating protection
• Automatic blocking when the voltage drops out of working conditions
• Cross-current protection
• Over voltage protection
The output power can be adjusted using the small potentiometer soldered to the board.
It is not recommended to modify the wiring of this (and other) electronic component while it is powered. For the use over long periods with currents close to the nominal value, we recommend to employ a
heat sink with every driver.
