Description
You want to make a cool robot, maybe a hexapod walker, or maybe just a piece of
art with a lot of moving parts. Or maybe you want to drive a lot of LEDs with precise
PWM output. Then you realize that your microcontroller has a limited number of
PWM outputs! What now? You could give up OR you could just get this handy PWM
and Servo driver breakout.
When we saw this chip, we quickly realized what an excellent add-on this would be.
Using only two pins, control 16 free-running PWM outputs! You can even chain up
62 breakouts to control up to 992 PWM outputs (which we would really like to see
since it would be glorious)
-
It's an i2c-controlled PWM driver with a built in clock. That means that, unlike the
TLC5940 family, you do not need to continuously send it signal tying up your
microcontroller, its 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 for 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 - that's a lot of servos or LEDs
-
Adjustable frequency PWM up to about 1.6 KHz
-
12-bit resolution for each output - for servos, that means about 4us resolution at 60Hz
update rate
-
Configurable push-pull or open-drain output
-
Output enable pin to quickly disable all the outputs
We wrapped up this lovely chip into a breakout board with a couple nice extras
-
Terminal block for power input (or you can use the 0.1" breakouts on the side)
-
Reverse polarity protection on the terminal block input
-
Green power-good LED
-
3 pin connectors in groups of 4 so you can plug in 16 servos at once (Servo plugs are
slightly wider than 0.1" so you can only stack 4 next to each other on 0.1" header
-
"Chain-able" design
-
A spot to place a big capacitor on the V+ line (in case you need it)
-
220 ohm series resistors on all the output lines to protect them, and to make driving LEDs trivial
-
Solder jumpers for the 6 address select pins
This product comes with a fully tested and assembled breakout as well as 4 pieces of 3x4 male
straight header (for servo/LED plugs), a 2-pin terminal block (for power) and a piece of 6-pin 0.1"
header (to plug into a breadboard). A little light soldering will be required to assemble and
customize the board by attaching the desired headers but it is a 15 minute task that even a beginner
can do. If you want to use right-angle 3x4 headers, we also carry a 4 pack in the shop.
Check out our tutorial with Arduino and you can get our documented Arduino library which has both
PWM and Servo examples from github!
TECHNICAL DETAILS
Specifications:

EasyDriver Shield Stepper Motor Driver V44 A3967 For Arduino
The EasyDriver is a simple to use stepper motor driver, compatible with anything that can output a digital 0 to 5V pulse (or 0 to 3.3V pulse if you solder SJ2 closed on the EasyDriver). EasyDriver requires a 7V to 30V supply to power the motor and can power any voltage of stepper motor.
