Opening it shows a confirmation page with live pricing and stock before anything is added to the cart. - **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/ADA2928:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.) - **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there. - **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description A Feather board without ambition is a Feather board without FeatherWings! This is the **8-Channel PWM or Servo? FeatherWing**, you can add 8 x 12-bit PWM outputs to your Feather board. Using our [Feather Stacking Headers](https://core-electronics.com.au/feather-stacking-headers-12-pin-and-16-pin-female-headers.html) or [Feather Female Headers](https://core-electronics.com.au/feather-header-kit-12-pin-and-16-pin-female-header-set.html) you can connect a FeatherWing on top or bottom of your Feather board and let the board take flight! You want to make a cool robot, maybe a hexapod walker, or maybe just a piece of art with a lot of moving parts. Or maybe you want to drive a lot of LEDs with precise PWM output. What now? You could give up OR you could just get Adafruit's handy PWM and Servo FeatherWing. It's a lot like Adafruit's popular [PWM/Servo Shield](https://core-electronics.com.au/adafruit-16-channel-12-bit-pwm-servo-shield-i2c-interface.html) but with half the channels & squished into a nice small portable size and works with any of Adafruit's Feather boards. Since the FeatherWing only uses the I2C (SDA & SCL pins), it works with any and all Feathers- ATmega32u4, ATSAM M0 or ESP8266-based. You can stack it with any other FeatherWing or with itself (just make sure you have each wing with a unique I2C address) [Check out Adafruit's range of Feather boards here.](https://www.adafruit.com/feather) **Specs**: - 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 Feather 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 **Adafruit wrapped up this lovely chip into a FeatherWing 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 - Two groups of 4 outputs on either side, 8 total. - Stackable design. You'll need to pick up stacking headers and right angle 3x4 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 This product comes with a fully tested and assembled wing as well as 2 pieces of 3x4 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 a Feather. 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. [If you want to use right-angle 3x4 headers, We also carry a 4 pack in the shop.](https://core-electronics.com.au/3x4-right-angle-male-header-4-pack.html) **Servos and Feather not included**, but [Adafruit have lots of servos in the shop](https://www.adafruit.com/categories/232). For additional information see Adafruit's tutorial for the bigger and similar PWM/Servo Shield plus you can get Adafruit's documented Arduino library which has both PWM and Servo examples! ## Technical Details - Dimensions: 50.8mm x 22.9mm x 1.6mm / 2" x 0.9" x 0.06" - Weight: 3.9g - [Datasheets, schematic, PCB CAD files, and Fritzing object available from the tutorial](https://learn.adafruit.com/adafruit-8-channel-pwm-or-servo-featherwing/downloads) ![](https://core-electronics.com.au/attachments/localcontent/rohs_icon_8216055e11.jpg) ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/2/9/2928-14.jpg)
