{"product_id":"16-channel-pwm-servo-control-board","title":"16 Channel PWM Servo Control Board","description":"\u003cp\u003eThis 16 Channel PWM Servo Control Board is a versatile module that allows you to control up to 16 servos using only 2 pins via I2C communication. Whether you're building a robot, animatronic project, or any application that requires precise servo control, the PCA9685 16-Channel Servo Driver is an excellent choice. It simplifies servo management and frees up valuable pins on your microcontroller.\u003c\/p\u003e\u003ch4\u003eFeatures\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThe PCA9685 offers 16 fully programmable PWM outputs with a 12-bit resolution, providing 4096 steps for precise duty cycle adjustments on each channel.\u003c\/li\u003e\n\u003cli\u003eThe module uses the I2C bus for communication, ensuring easy integration with microcontrollers like Arduino or Raspberry Pi.\u003c\/li\u003e\n\u003cli\u003eSupports frequency control across all 16 channels, programmable between 24Hz and 1526Hz.\u003c\/li\u003e\n\u003cli\u003eThe duty cycle (pulse width) can be fine-tuned from 0% to 100% for accurate output control.\u003c\/li\u003e\n\u003cli\u003eThe on-board PWM controller manages all 16 channels independently, reducing processing load on the microcontroller compared to direct pin-based servo control.\u003c\/li\u003e\n\u003cli\u003eMultiple modules can be daisy-chained together. With up to 62 boards on a single I2C bus, you can control up to 992 servos using just two pins.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eSpecifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e Without headers or terminal block: 2.5 x 25.4 x 3mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight Without headers or terminal block:\u003c\/strong\u003e 5.5g\u003c\/li\u003e\n\u003cli\u003eWeight With 3x4 headers and terminal block: 9g\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt-in Clock:\u003c\/strong\u003e Free-running PWM driver, eliminating the need for continuous microcontroller signals\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Control:\u003c\/strong\u003e Output enable pin for quickly disabling all outputs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLED:\u003c\/strong\u003e Green power-good LED for easy diagnostics\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpace:\u003c\/strong\u003e Ideal for adding a large capacitor on the V+ line to stabilize power input\u003c\/li\u003e\n\u003cli\u003eTerminal block with reverse polarity protection\u003c\/li\u003e\n\u003cli\u003eOptional 0.1\" breakout pins for flexible power connection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e7-bit address range:\u003c\/strong\u003e 0x60–0x80, selectable with solder jumpers\u003c\/li\u003e\n\u003cli\u003eConnects to microcontrollers (e.g., Arduino) with 4 lines; 5V -\u0026gt; VCC, GND -\u0026gt; GND, SDA (data) and SCL (clock)\u003c\/li\u003e\n\u003cli\u003e16 channels with 3-pin connectors grouped in sets of 4\u003c\/li\u003e\n\u003cli\u003eEach output includes 220-ohm series resistors for protection and easy LED control\u003c\/li\u003e\n\u003cli\u003eConfigurable as push-pull or open-drain output\u003c\/li\u003e\n\u003cli\u003e12-bit resolution per channel (4096 steps)\u003c\/li\u003e\n\u003cli\u003eAdjustable PWM frequency up to 1.6 KHz\u003c\/li\u003e\n\u003cli\u003e~4µs resolution at a 60Hz update rate (ideal for servos)\u003c\/li\u003e\n\u003cli\u003eFeatures 6 address select pins\u003c\/li\u003e\n\u003cli\u003eSupports daisy-chaining of up to 62 boards on a single I2C bus\u003c\/li\u003e\n\u003cli\u003eTotal of 992 outputs can be controlled (ideal for large servo or LED projects)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e5V compliant:\u003c\/strong\u003e Safe to use with 3.3V microcontrollers while driving outputs up to 6V\u003c\/li\u003e\n\u003cli\u003eSupports LEDs with higher forward voltages (e.g., white or blue LEDs at 3.4V+)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Altronics","offers":[{"title":"Default Title","offer_id":67726325416209,"sku":"ALT-Z6493","price":24.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0786\/7786\/8817\/files\/0045443_16-channel-pwm-servo-control-board.webp?v=1791971636","url":"https:\/\/www.teachersuperstore.com.au\/products\/16-channel-pwm-servo-control-board","provider":"Teacher Superstore","version":"1.0","type":"link"}
