## Required parts
The following parts list will allow you to build:
- 1x powered winder (required)
- 2x unpowered winders (optional)
- 2x un-powered winders (optional)

This means that you'll be able to construct a 3-watch winder. Remember that the system is modular, so if you decide to only build a single powered winder, that's ok.


### Total cost of required Parts
- **$40.00 (February 2023)**

> [!NOTE]
> The following tables contains affiliate links to Aliexpress; **you do not pay an inflated price because of this.** Should you decide to use another supplier, please ensure that you cross-reference this table and buy identical components.
>
> While most of these components are standardized, I will not be able to assist you if you purchase your components from a separate supplier, as the winder was designed around the components (as supplied) beneath.
> [!CAUTION]
> If you're planning a [Widneroo](https://github.com/mwood77/winderoo) build, do not purchase a Raspberry Pi Pico. Purchase an ESP32 instead to save some money and avoid future headaches. You can find a link to purchase an ESP32 in [Winderoo's Bill of Materials](https://github.com/mwood77/winderoo/blob/main/docs/bom-requirements.md).
