NSHIELD Quickstart Guide

The N-Drive Shield gives your Arduino the ability to drive up to six individual DC loads such as

LEDs, DC motors and solenoids at up to a maximum of 60V / 20A per channel (with adequate

cooling) using N-channel MOSFETs.

Safety First!

This shield is not suitable for switching mains level voltages.

It is possible to miswire the NDrive Shield in ways that create a lot of heat and potentially start a

fire or burn you! Don't power up anything you're not sure about.

Hardware Setup

1. Fit the NDrive Shield to your Arduino. The shield includes extended “R3” headers, but it is

also compatible with older Arduino models without the new SCL, SDA, and IOREF pins. If you

do not need these pins you can cut them off if they get in the way, as they are not used by the

shield.

2. Connect the loads you wish to switch on and off via the NDrive Shield. The screw terminals

provide 6 outlets for the “Drain” connections of the MOSFETs. Each channel is controlled by a

single digital pin (3, 5, 6, 9, 10, 11) and is marked on the shield.

Connect each load as follows:

For inductive loads (such as motors or solenoids), you will also need a flyback diode to protect

the circuit.

Software Setup The six output channels on the N-Drive Shield are connect to 6 digital outputs on your Arduino. The outputs are biased off by default, and can be turned on by driving the matching output HIGH. Digital Control Even a simple example such as Blink can be used simply by changing the pin.
