It communicates over I2C, allowing you to daisy-chain up to 62 modules on a single bus using selectable address jumpers. Ideal for building multi-servo robotics arms, animatronics, or LED dimming, this module offloads PWM generation from your microcontroller.\u003c\/p\u003e\u003ch2\u003eKey Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePWM Channels\u003c\/td\u003e\n\u003ctd\u003e16\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResolution\u003c\/td\u003e\n\u003ctd\u003e12-bit (4096 steps)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency Range\u003c\/td\u003e\n\u003ctd\u003e24 Hz to 1526 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInterface\u003c\/td\u003e\n\u003ctd\u003eI2C (up to 1 kHz)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLogic Voltage\u003c\/td\u003e\n\u003ctd\u003e2.3V ~ 5.5V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/kit-4-axis-servo-arm-basic\"\u003e6-axis robotic arm with independent servo control\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003ePan-tilt camera gimbal for surveillance systems\u003c\/li\u003e\n\u003cli\u003eAnimatronic puppet with synchronized motions\u003c\/li\u003e\n\u003cli\u003eCustom LED mood lighting with 16 individually dimmable channels\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCompatibility\u003c\/h2\u003e\u003cp\u003eThis PWM driver works with any 3.3V or 5V microcontroller that supports I2C, including Arduino Uno, Mega, Nano, Raspberry Pi, ESP32, and STM32. Its logic pins are 5V tolerant, so you can safely interface with 3.3V boards without level shifting. It pairs perfectly with standard analog servos like SG90, MG995, and MG996R.\u003c\/p\u003e\u003ch2\u003eWiring Notes\u003c\/h2\u003e\u003cp\u003eConnect the module’s SDA and SCL pins to your microcontroller’s I2C lines. Provide a separate 5V–6V power supply to the terminal block for servo power, ensuring the ground is shared with the microcontroller. Do not power servos directly from the Arduino’s 5V pin to avoid overcurrent damage.\u003c\/p\u003e\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.\u003c\/p\u003e\u003cdetails\u003e\u003csummary\u003eIs this compatible with Raspberry Pi?\u003c\/summary\u003e\u003cp\u003eYes, the PCA9685 uses I2C, which is natively supported on Raspberry Pi. Just enable I2C in raspi-config and install the Adafruit_PCA9685 Python library to get started.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eCan I power servos directly from this module?\u003c\/summary\u003e\u003cp\u003eNo, the module does not include a servo power supply. You must connect an external 5V–6V power source to the green terminal block on the board to drive your servos.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eHow many modules can I chain together?\u003c\/summary\u003e\u003cp\u003eYou can chain up to 62 PCA9685 modules on a single I2C bus by bridging different address jumpers on each board. This allows controlling up to 992 servos from one microcontroller.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdiv class=\"compoden-handoff\" style=\"margin-top:24px;padding:16px;background:#f0f4ff;border-left:4px solid #2B4D8F;border-radius:4px;\"\u003e\n  \u003cp style=\"margin:0 0 6px 0;font-weight:600;color:#1A3560;\"\u003e📦 Free Setup Handoff Document Included\u003c\/p\u003e\n  \u003cp style=\"margin:0;font-size:0.95em;color:#333;\"\u003eEvery Compoden order includes a free setup handoff document — step-by-step instructions to get your component working within minutes.
