== Alimentation ==
The driver requires a motor supply voltage of 4.5 V to 35 V to be connected across VMOT and GND. This supply should have appropriate decoupling capacitors close to the board, and it should be capable of delivering the expected stepper motor current. The driver has an internal voltage regulator, so it does not require a logic voltage supply.
{{ambox-stop|text=This carrier board uses low-ESR ceramic capacitors, which makes it susceptible to destructive LC voltage spikes, especially when using power leads longer than a few inches. Under the right conditions, these spikes can exceed the 40 V absolute maximum voltage rating for the MP6500 and permanently damage the board, even when the motor supply voltage is as low as 12 V. One way to protect the driver from such spikes is to put a large (at least 47 µF) electrolytic capacitor across motor power (VMOT) and ground somewhere close to the board.}}
== Connexion moteur ==
Four, six, and eight-wire stepper motors can be driven by the MP6500 if they are properly connected; a [https://www.pololu.com/product/2966?tab=faqs FAQ answer] (''Pololu, anglais'') explains the proper wirings in detail.
{{ambox-stop|text=Warning: Connecting or disconnecting a stepper motor while the driver is powered can destroy the driver. (More generally, rewiring anything while it is powered is asking for trouble.)}}
