The arduino can also supply power to the motor, but normally this is only a good idea for demonstration purposes. The arduino has a very weak power supply, and attempting to power a motor through it can destroy the arduino. Furthermore, the arduino may not be able to supply the exact correct maximum voltage. For this reason, an ESC is placed between the arduino and the motor.

In fact, it is recommended, because the IC pad pitch is just 0.5 mm, that only one solder mask opening should be used for all four pads on one side. It is also suggested, when using solder paste printing, that a laser-cut stainless steel stencil with trapezoidal walls and with a stencil thickness of 0.1 or 0.125 mm should be used. See the images below. This information should be quite helpful for a PCB layout design team.

Look at these wikicommons pictures. Taking apart a CD player and finding the motor is fairly easy.Start by turning it upside down and removing the screws holding the bottom plate on.

Working safelyDisconnect both terminals of the battery before doing any work on wiring other than testing. Whenever you work on the car, watch for any part of the loom coming loose from its clips, for there is a risk of it getting trapped or burned. Always replace wiring in its clips.

Grip the cable, connector uppermost, in a vice or self-locking pliers, so that the connector rests on top of the vice and cannot slide down the wire when soldering. Inside a bullet connector. Apply solder on the top of the connector, and let it melt and run down inside. Trim off the protruding strands with wire cutters.

Brushes are used to create electrical contact to the commutator segments and when current is fed into two of the four brushes, it flows through all the loops of the armature and shoe windings and out the other two brushes. This creates a magnetic field around each loop. As the armature turns, the loop will move to a position where the current flow reverses. This constant reversal of current flow allows the armature and field coils to repel each other and spin the motor. The greater the current flowing in the coils, the greater the magnetic forces, and the greater the power of the motor.

Although this device uses an I2C interface with communication speeds up to 1 MHz, two of the eight pins are dedicated to Alert (pin3) and nReset (pin 6). The Alert pin is intended to be connected, if desired, to an interrupt pin on a microcontroller. According to section 3.5 (ALERT Pin) of the datasheet, "The output of the pin depends on the value of the temperature reading relative to programmable limits," and its function is "explained in a separate application note.

In my opinion, it is not wise to restrict yourself to two layers unless you’re dealing with a very simple circuit or you really need to cut costs. The four-layer arrangement is beneficial in terms of routing and performance: routing, because via connections to internal planes almost completely eliminate power and ground traces; and performance, because the internal planes allow for low-resistance, low-inductance power and ground connections. The extra top-layer and bottom-layer real estate opened up by all the internal-plane connections come in very handy when you need to provide a generous copper area for improved thermal performance (for example, to make sure that your LDO or your motor driver doesn’t overheat and enter thermal shutdown).
