If you want to make a robot which has lots of moving parts or if you want to control too many LEDs with PWM outputs,  then the limited PWM outputs of your microcontroller would be a big problem for you. To overcome this problem, the only thing you should do is to get a 16-Channel 12-Bit PWM/Servo Driver.

You can control 16 free-running PWM outputs with 16-Channel 12-Bit PWM/Servo Driver using only 2 pins. You can even chain up 62 breakouts to control up to 992 PWM outputs.

It’s an I2C-controlled PWM driver with a built-in clock. That means you do not need to continuously send it to signal to tie up your microcontroller, it is completely free running!

It is 5V compliant, which means you can control it from a 3.3V microcontroller and still safely drive up to 6V outputs. This is good when you want to control white or blue LEDs with 3.4+ forward voltages. 6 address select pins so you can wire up to 62 of these on a single I2C bus, a total of 992 outputs.

Features :

1. Adjustable frequency PWM up to about 1.6 KHz
2. 12-bit resolution for each output – for servos, that means about 4us resolution at a 60Hz update rate
3. Configurable push-pull or an open-drain output
4. The output enable pin to quickly disable all the outputs
5. Terminal block for power input
6. Reverse polarity protection on the terminal block input
7. Green power-good LED
8. 3 pin connectors in groups of 4 so you can plug in 16 servos at once
9. Chainable design
10. A spot to place a big capacitor on the V+ line
11. 220-ohm series resistors on all the output lines to protect them, and to make driving LEDs trivial.
12. This board/chip uses I2C 7-bit address between 0x60-0x80, selectable with jumpers.

The Towerpro MG90S Mini Digital Servo is 180° rotation servo. It is a Digital Servo Motor which receives and processes PWM signal faster and better. It equips sophisticated internal circuitry that provides good torque, holding power, and faster updates in response to external forces.

The good optimized performance and reliability of our servos have made them the favorite choice of many RC hobbyists.

They are packed within a tight sturdy plastic case which makes them water and dust resistant which is a very useful feature in RC planes, Boats, and RC Monster Trucks etc. It equips 3-wire JR servo plug which is compatible with Futaba connectors too.

The A4988 driver Stepper Motor Driver is a complete micro-stepping motor driver with built-in converter, easy to operate. It operates from 8 V to 35 V and can deliver up to approximately 1 A per phase without a heat sink or forced air flow (it is rated for 2 A per coil with sufficient additional cooling).

A4988 driver Stepper Motor Driver includes a fixed off-time current regulator, the regulator can be in slow or mixed decay mode. The converter is the key to the easy implementation of the A4988.

There are no phase sequence tables, the high-frequency control interface programming etc. The application of A4988 interface is very suitable for a complex microprocessor is not available or overload. In the stepping operation, the chopping control in the A4988 automatically selects the current decay mode (slow or mixed). The mix decay current control scheme can reduce the audible motor noise, increased step accuracy, and reduced power consumption.

Provide internal synchronous rectification contr

ol circuitry, in order to improve the pulse width modulation (PWM) power consumption during operation.

Internal circuit protection includes thermal shutdown with hysteresis, under-voltage lockout (UVLO) and crossover current protection. Don’t need special power-up sequencing. A4988 uses surface mount QFN package (ES), the size is 5 mm × 5 mm, nominal overall package height is 0.90 mm, with an exposed thermal pad to enhance the heat dissipation function.

Features :

1. Automatic current decay mode detection/choice.
2. Mixed with slow current decay mode.
3. The low power dissipation of synchronous rectifier.
4. Internal UVLO(ultra voltage lockout).
5. Crossover current protection.
6. Thermal shutdown circuit.
7. Ground fault protection.
8. Loading and short circuit protection.
9. The optional five-step mode: full, 1/2, 1/4, 1/8 and 1/16.

Package Includes :

1 x A4988 Stepper Motor Driver- Normal quality.
