8-Channel PWM or Servo FeatherWing Plugin for All Feather Boards

8-Channel PWM or Servo FeatherWing Plugin for All Feather Boards

This is the 8-Channel PWM or Servo FeatherWing, which allows you to add 8 x 12-bit PWM outputs to your Feather board.

Imagine you have a cool robot, maybe a 6-legged walker or a piece of interactive art with a lot of moving parts. Or you want to control a lot of LEDs with precise PWM output. What now? You could give up OR you could just get our handy PWM/Servo Kalkannına FeatherWing. It's a lot like our popular PWM/Servo Shield but with half the channels & squished into a smaller, portable 'wing.

Since the FeatherWing only uses the I2C (SDA & SCL pins), it works with any Feather and can stack with any other FeatherWing or itself (just make sure each Wing has a unique I2C address).

Features

• It has an I2C-controlled PWM driver with a built-in clock. Unlike the TLC5940 family, this means you don't need to continuously send signals by tying up your microcontroller; it operates completely independently.

• It's 5V compatible, so you can control it from a 3.3V Feather and still safely drive outputs up to 6V. This is useful when you want to control white or blue LEDs with forward voltages of 3.4V or higher.

• You can stack up to 62 of these on a single I2C data bus by using the 6 address select pins, for a total of 992 outputs. This means you can control a large number of servos or LEDs.

• Adjustable PWM frequency up to about 1.6 KHz.

• 12-bit resolution for each output. For servos, this means approximately 4us resolution at a 60Hz update rate.

• Configurable push-pull or open-drain output.

• We've packaged this lovely chip into a FeatherWing with several 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.
  • Two groups of 4 outputs on both sides, for a total of 8.
  • Stackable design. To stack this Wing on top of another without interference, you'll need to get a set of stacking headers and extra 3x4 headers.
  • 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 make driving LEDs trivial.
  • Jumper wires for the 6 address select pins.

This product comes as a fully assembled FeatherWing along with 2 pieces of 3x4 male straight headers (for servo/LED plugs), a 2-pin terminal block (for power), and a 0.1" header you can use to plug into a breadboard or perfboard. To attach it to a Feather, you will need to do some light soldering. However, even beginners can easily accomplish this in about 10 minutes.

Note:  The terminal blocks included with your product may be either blue or black. Servos are sold separately
