Product Description
* 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
Feature
* • 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)
* • 330 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

FAQ
Q1.What is needed for quotation?
A1: PCB : Quantity, Gerber file and Technic requirements(material,surface finish treatment, copper thickness,board thickness ,...) PCBA: PCB information, BOM, (Testing documents...)

Q2: MOQ?
A2: There is no MOQ in Smart.We are able to handle Small as well as large volume production with flexibility.
Q3: Which type of PCBs do you expert in?
A3: We are specialized in producing Singe-side PCB,Double-side PCB, Multilayer PCB,Aluminium PCB,Spray Tin PCB,Immersed Gold PCB, etc.
Q4: What is your Lead time?
A4: Lead time is usually punctual here, usually 5-10 days for PCB sample, 10-15 days for mass production. For some special situation,we can also advise customer in advance to avoid any inexpectation or loss at customer side.
Q5: I only have the pcb sample, not pcb file, can you produce it for me?
A5: Yes, we can copy file based on your sample, this file names gerber, and production then is accorded to gerber file.
Q6: What is your testing policy and how you controle the quality?
A6: For sample, usually tested by flying probe; for PCB Volume over 3 square meters, usually tested by fixture, this will be more faster. Due to there’s many steps to PCB production, we usually do inspection after every step.
Q7: Will you allow me to put several part number together into one panel?
A7: Yes, this is usually happen in we factory, this way can help customers reduce some cost and to a certain degree, it can help reduce some assembly cost.
Q8: Will my file be safe after you get it ?
A8: Yes , we will not release your design to third party unless with your permission .And we can signthe NDA before you send the file.
Q9: Do you accept process materials supplied by clients?
A9: Yes, we can provide component source, and we also accept component from client
Q10: PCB shipment?
A10: This is depend on customer, sometimes we ship through our forwarder, who is also the agency of DHL, TNT, UPS, Fedex, and soon.Our forwarder can provide too much better freight cost than we get directly from those express enterprise.
Q11: Shipping cost?
A11: The shipping cost is determined by the destination, weight, packing size of the goods. Please let us know if you need us to quote you the shipping cost.
