Adafruit 16-Channel PWM / Servo HAT for Raspberry Pi – Mini Kit
13,95€ IVA Inclusa
5184 (Adafruit-Compatible)16-Channel 12-bit PWM Servo shield I2C interface PCA9685 Using only two pins, control 16 free-running PWM outputs! You can even chain up 62 breakouts to control up to 992 PWM outputs • 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 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 Package Included: 1x (Adafruit-Compatible)16-Channel 12-bit PWM Servo shield I2C interface PCA9685 （Does not include servos）
