Or maybe you want to drive a lot of LEDs with precise PWM output. Then you realize that the Arduino has only a few PWM outputs, and maybe those outputs are conflicting with another shield! What now? You could give up OR you could just get our handy PWM and Servo driver shield. It's just like our popular PWM\/Servo Breakout but now Arduino-ready and works with any Arduino that uses shields: Uno, Leo, Mega, ADK, it's all good.\u003c\/p\u003e\n\u003cp\u003eWhen we saw this chip, we quickly realised what an excellent add-on this would be. Using only two I2C pins, control 16 free-running PWM outputs! You can even stack up 62 shields to control up to 992 PWM outputs (which we would really like to see since it would be glorious and like 4 feet tall) Because I2C is a shared bus you can also connect other I2C devices and sensors to the SCL\/SDA pins as long as their addresses don't conflict (this shield has address 0x40)\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThere'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!\u003c\/li\u003e\n\u003cli\u003eIt is 5V compliant, which means you can control it from a 3.3V Arduino 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)\u003c\/li\u003e\n\u003cli\u003e6 address select pins so you can stack up to 62 of these on a single i2c bus. 12 out of 16 output pins can be accessed when stacked.\u003cbr\u003eAdjustable frequency PWM up to about 1.6 KHz\u003c\/li\u003e\n\u003cli\u003e12-bit resolution for each output - for servos, that means about 4us resolution at 60Hz update rate\u003c\/li\u003e\n\u003cli\u003eConfigurable push-pull or open-drain output\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWe wrapped up this lovely chip into a shield with a couple of nice extras\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eTerminal block for power input (or you can use the 0.1\" breakouts on the side)\u003c\/li\u003e\n\u003cli\u003eReverse polarity protection on the terminal block input\u003c\/li\u003e\n\u003cli\u003eGreen and red power-good LEDs\u003c\/li\u003e\n\u003cli\u003e3 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\u003c\/li\u003e\n\u003cli\u003eStackable design. You'll need to pick up stacking headers and right-angle 3x4 headers in order to stack on top of this shield without the servo connections getting in the way.\u003c\/li\u003e\n\u003cli\u003eA spot to place a big capacitor on the V+ line (in case you need it)\u003c\/li\u003e\n\u003cli\u003e220 ohm series resistors on all the output lines to protect them, and to make driving LEDs trivial\u003c\/li\u003e\n\u003cli\u003eSolder jumpers for the 6 address select pins\u003c\/li\u003e\n\u003cli\u003eA lot of extra space remaining? Let's turn it into a prototyping area. You get a 5x20 proto area for any extra wiring you'd like to add\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThis product comes with a fully tested and assembled shield as well as 4 pieces of 3x4 male straight header (for servo\/LED plugs), a 2-pin terminal block (for power) and a stick of 0.1\" header so you can plug into an Arduino. A little light soldering will be required to assemble and customise 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 - \u003cstrong\u003enote that only 3 of them can be used when stacking (12 servos total).\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eServos and Arduino are NOT included\u003c\/strong\u003e - but we do sell tons of different servos in the shop so pick up a few while you're here!\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote\u003c\/strong\u003e: The terminal blocks included with your product may be blue or black.\u003c\/p\u003e\n\u003cp\u003eCheck out our tutorial with Arduino and you can get our documented Arduino library which has both PWM and Servo examples!\u003c\/p\u003e\n\u003ch3\u003e\u003cb\u003eRevision History:\u003c\/b\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eAs of July 29th, 2024\u003c\/b\u003e – we've updated this PCB with Adafruit Pinguin to make a lovely and legible silkscreen - you may get the new PCB or the older version with vector fonts - both are identical other than the fancy silkscreen.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDimensions (no headers or terminal block) 54mm x 70mm x 3mm\u003c\/li\u003e\n\u003cli\u003eThis board\/chip uses I2C 7-bit addresses between 0x60-0x80, selectable with jumpers.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eTutorial and Downloads\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c!----\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":44930762899545,"sku":"dcf1789672210952","price":15.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0736\/5289\/5833\/files\/adafruit-16-channel-12-bit-pwmservo-shield---i2c-interface_1.jpg?v=1789672216","url":"https:\/\/gymflexfit.shop\/products\/adafruit-16-channel-12-bit-pwmservo-shield-i2c-interface","provider":"My Store","version":"1.0","type":"link"}
