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)

The Raspberry Pi is a wonderful little computer, but one thing it isn't very good at is controlling DC Servo Motors - these motors need very specific and repetitive timing pulses to set the position. Instead of asking the Pi Linux kernel to send these signals, pop on this handy HAT! It adds the capability to control 16 Servos with perfect timing. It can also do PWM up to 1.6 KHz with 12 bit precision, all completely free-running. For use with Raspberry Pi Model A+, B+, or Pi 2 can be used with the Model A or B if you use a tall 2x13 header instead of the included 2x20. The Adafruit 16-Channel 12-bit PWM/Servo HAT will drive up to 16 servos or PWM outputs over I2C with only 2 pins. The on-board PWM controller will drive all 16 channels simultaneously with no additional Raspberry Pi processing overhead. What's more, you can stack up to 62 of them to control up to 992 servos - all with the same 2 pins! Best of all, we even have a Python library you can use, so you'll be up and running instantly, to make your robotic creation com to life. The Adafruit PWM/Servo HAT is the perfect solution for any project that requires a lot of servos or PWM outputs! Please check out our detailed tutorial for lots more information including diagrams, schematics, installation instructions and more Each order comes with a Servo HAT, a 2-pin terminal block, four 3x4 headers and a 2x20 socket header. You'll need to do some light through-hole soldering to attach the headers onto the HAT circuit board, but its easy to do with basic soldering tools like a soldering iron and rosin core electronics solder. If you would like to stack multiple HATs onto one Pi, you can also pick up a 2x20 stacking header and a set of right-angle 3x4 headers that should be soldered on instead. Please note! This kit does not come with Raspberry Pi, servos, or required 5V power supply. We have recommendations on the required 5-6V power supply on the tutorial page, and a whole bunch of servo
