# Tako

Tako is a vertical stagger split keyboard with electrostatic capacitive (EC) non-contact switches.

## Bill Of Materials (BOM)

### Production Files

Depending on which parts you are going to use, make sure to select the proper top plate (OG or NIZ). Ensure you use the correct thickness - the **OG (OEM, Deskeys, etc) plate should be 1.2mm**, and the NIZ should be 1.6mm!

### MCU

RP2040-based boards should be used for wired build - Liatris, Frood, Sea-Picro, Splinky, [etc](https://github.com/qmk/qmk_firmware/blob/master/docs/platformdev_rp2040.md#rp2040-community-edition-idrp2040_ce).

**ATmega32U4 (Pro Micro) won't work.**

#### Wireless

For a wireless build, you can use [nice!nano](https://nicekeyboards.com/nice-nano/). Keep in mind that EC matrix consume significantly more power than mechanical keyboards. An 80mAh battery placed under the MCU will last for about a day only. I don't have exact numbers yet (still waiting for a power profiler), but you will likely need to use a larger battery. Consider using longer standoffs with a 3D-printed or acrylic spacer between the PCB and the bottom plate, and place the battery there.

### Display

5 pins for [nice!view](https://nicekeyboards.com/nice-view/) are exposed. 128x32 OLED can be used on first 4 pins but won't be perfectly centered.

### EC Parts

| Part            | Amount |
|-----------------|--------|
| Housings        | 34     |
| Domes           | 34     |
| Conical springs | 34     |
| Sliders         | 34     |
| Silencing rings | 34     |

- If you going to use DES V3/Carrot domes then it's recommended to get DES Volcano springs to avoid sping crunch.
- Silencing rings are recommended for DES parts. If you want the same key travel as HHKB Type-S with DES housings and DES sliders then you should get #7 rings.

Some EC vendors:

- [deskeys](https://deskeys.io/)
- [NIZ Store](https://www.nizkeyboard.com/products/2019-new-niz-ec-switch)
- [Beekeeb (NIZ)](https://shop.beekeeb.com/product/niz-ec-switch/)
- YMDK [Housings](https://aliexpress.com/item/1005005724051113.html), [Sliders](https://aliexpress.com/item/1005005721976294.html) and [Domes](https://aliexpress.com/item/1005005721050116.html)

**You can only use MX-compatible sliders due to the housing orientation.** [See details](./docs/housing_orientation.md).

NIZ sliders are MX-compatible by default.
