## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE09181:1` (comma-separated SKU:qty pairs) and share the link. 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/CE09181:1.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)

## Description

Nothing makes a project more exciting like *motion,* and now it's easier than ever with the **PiicoDev® Servo Driver**. You can control up to four RC Servos independently to create angular or continuous rotational motion. Use it to open and close a gate, beat a drum or pluck a string, or even equip your robot army with grabby claws!

The PiicoDev Servo Driver features a dedicated PWM chip that takes care of generating the servo signals, all you need to do is tell it what angle or speed you want to set your servo. There are the regular daisy-chainable PiicoDev connectors so you can add this module to your project without soldering - and additional USB-C connectors to provide separate, high-current power to your servos. Better still, the Servo Driver has four addressing options set by the Address Switch (ASW) - you can daisy chain up to four Drivers together for a maximum of 16 servos! That ought to be enough for most projects.

We've prepared a [great guide](https://core-electronics.com.au/guides/piicodev/piicodev-servo-driver-pca9685-getting-started-guide/) full of useful examples to help you get started working with your favourite development board in Python/MicroPython.

**Features**

- Control up to four servos independently
- Daisy chain up to four Servo Drivers together for more complex projects
- No soldering necessary
- A great [guide](https://core-electronics.com.au/guides/piicodev/piicodev-servo-driver-pca9685-getting-started-guide/) to get you started
- PiicoDev connector, compatible with Qwiic and STEMMA QT (3.3V only)
- 2.54mm breakout for breadboarding/prototyping
- Manufactured and [supported](https://core-electronics.com.au/contacts/) in Australia by Core Electronics
 
**Getting Started Guides**

We've prepared a [getting-started guide](https://core-electronics.com.au/guides/piicodev/piicodev-servo-driver-pca9685-getting-started-guide/) that works with Raspberry Pi, Pico, and Micro:bit.

**Picking the right servo and power supply**

We recommend getting started with either the [FS90 Micro Servo](https://core-electronics.com.au/feetech-fs90-1-5kgcm-micro-servo-9g.html), or [FS90R Continuous Rotation Micro Servo](https://core-electronics.com.au/feetech-1-5kg-continuous-rotation-servo-fs90r.html).

Servos are pretty power-hungry! We recommend a [quality power supply](https://core-electronics.com.au/raspberry-pi-4-official-power-supply-usb-c-5v-15w-white.html), and budgeting about 0.7A per micro-servo, and as much as 2.4A per standard servo. This all depends on what you're asking your servo to do - how fast to move and how much torque to deliver. See the [guide](https://core-electronics.com.au/guides/piicodev/piicodev-servo-driver-pca9685-getting-started-guide/) for more information.

For some inspiration, we've successfully driven this [3-DOF Robot Arm](https://core-electronics.com.au/3dof-robot-arm-kit-diy.html) with the PiicoDev Servo Driver. While this requires three larger servos, the overall current demand is not excessive since the movements are smooth.

Here are some of the features we have baked into PiicoDev:

- **Unified MicroPython libraries.** The same MicroPython code examples will work on all supported platforms.
- **Simple-and-expandable connections.** Modules can be connected using a 4-pin connector and daisy-chained to expand projects.
- **Breakout pins.** Every module has a breakout section for optional advanced uses.
- **Consistent size.** We have taken care to ensure modules are consistent sizes so that they easy for 3D printing cases, stacking and experimenting with.
- **Creative freedom.** Simmer all of these features together and you end up with lots of creative freedom while still being a hands-on electronics experience.
 
PiicoDev modules are designed by our team in Newcastle and manufactured in Australia and overseas. They’re made for makers and educators alike — affordable, reliable, and easy to use. [Get in touch](https://core-electronics.com.au/contacts/) if you have any questions.
