16-Channel 12-bit PWM/Servo HAT for Raspberry Pi Mini Kit

16-Channel 12-bit PWM/Servo HAT for Raspberry Pi Mini Kit  

Product Description:
- 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 Zero, A+, B+, Pi 2 or Pi 3 (any Pi with 2x20 header) 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.
- Works with any servo that can be powered by 5V and take 3.3V logic level signals.
- 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.
 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)
- With the adafruit 16-channel 12-bit PWM/servo can you up to 16 servos via I2C controlled with only two pins. The on board PWM controller offers 16 PWM outputs simultaneously - used without also taking up the processor of the raspberry PIs. theoretically 62 HATs can be attached together, allowing up to 992 PWM outputs.
- The Board was for use with raspberry PI model A +, B +, 2 pi, PI 3 and PI zero (each raspberry PI with 2 x 20 pin headers) designed, but also suitable for model A and B, if 2 x 13 socket connectors are soldered. 2 x 20 socket connectors are delivered with.
- Works with all servos with 5V supply and a Logic level of 3,3 can be operated V.
- The HAS is delivered assembled and tested. The male and female strips are not soldered! Stackable Female Header, Raspberry Pi and servos are not included, but can also be ordered from us.

Details:
- There’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 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)
- 6 address select pins so you can stack 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
- 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 and red power-good LEDs
- 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
- Stackable design. You’ll need to pick up stacking headers and right angle 3×4 headers in order to stack on top of this shield without the servo connections getting in the way.
- A spot to place a big capacitor on the V+ line (in case you need it)
- 220 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
- A lot of extra space remaining?Let’s turn it into a prototyping area. You get a 5×20 proto area for any extra wiring you’d like to add
- This product comes with a fully tested and assembled shield as well as 4 pieces of 3×4 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 customize the board by attaching the desired headers but it is a 15 minute task that even a beginner can do.

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 options in the Adafruit shop, any 3-pin classic DC hobby servo will work.
