    Harika bir robot ya 6 ayaklı yürüyen bir mekatron mu yapmak istiyorsunuz? Belki de isteğiniz hareketli parçaları olan bir sanat eseri ya da hassas PWM çıkışıyla bir dizi LED sürmek istiyorsunuz. Mikrodenetleyicinin sınırlı sayıda PWM çıkışı olduğunu fark etmişsinizdir. Peki ne yapmalı vaz mı geçeceksiniz? Hayır, buna gerek yok tek yapacağınız kullanışlı bir PWM ve Servo sürücüsü almak.

    Bu entegreyi görür görmez ne kadar mükemmel bir ürün oluşturma potansiyelinin farkına vardık. Sadece ilki pin kullanarak 16 bağımsız PWM çıkışına sahip olacaksınız.! İsterseniz 62 kartı bir araya getirip 992 PWM çıkışına sahip olabilirsiniz. (Böyle bir şey yaparsanız biz de görmek isteriz çünkü harika olacağına eminiz)

    • 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 areslightly 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!
