[IC] BT60 - Bluetooth 60% PCB (More Layouts Added)
« on: Fri, 26 February 2021, 11:53:34 »
UPDATE 04/03/2021:

After the initial post, a lot of comments were asking for a soldered version with support for multiple layouts. So we decided to go ahead and design just that, it will be sold alongside the hotswap version of the board and has support for the following layouts:







It also has support for a rotary encoder, either in the top right or to the right of a 1.75u right shift. We also tried to fit on a split spacebar but that wouldn't have left space for the module, which lives under the spacebar area. Currently, we are working on testing the new PCB. We are happy with it so far and we will be sending units to beta testers shortly.
BT60 - Wireless 60% PCB with standard footprint






The Polarity Works BT60, a simple, functional, hotswap wireless 60% that drops into most cases. The BT60 focuses on a polished experience rather than every bell and whistle. The Nordic Semiconductor BLE module delivers high performance and excellent range even in metal cases, and in conjunction with ZMK, it delivers the functionality to match. Zephyr's energy optimisation delivers fantastic battery life and with an easy-to-use UF2 bootloader making changes is as simple as drag and drop, no DFU drivers, no programming software, just double-tap reset or use the bootloader keycode and it pops up as a thumb drive. If you wish to make customisations ZMK's module-centric design lets you make changes without installing build environments or screwing around with path variables, just set up a ZMK-config GitHub repository, then build it in the cloud with GitHub actions and download the UF2 directly to your keyboard!
As a drop-in replacement for any DZ60 footprint PCB, it's an easy and inexpensive upgrade to free yourself from wires for weeks at a time.

Quick Demo - https://youtu.be/OJloE9lCjD8

Features:

- Bluetooth connectivity
- Weeks of battery life (battery included)
- Fits into most 60% cases
- Hotswap sockets
- Standard ANSI layout


Price:

50-60

We are still gauging interest and confirming with manufacturers so this is just an estimate. We don't expect this to be higher, though it could drop if there is enough interest.

Great job using zmk! Any chance you could offer a solder version too? I prefer the stronger mechanical connection and greater layout options. (split bs and rs pls)

We definitely want to offer a soldered version in the future with lots of options for layouts. For the initial batch the plan is to go with just hotswap

Looks cool! Any chance that you'd add cut-outs on the edge to fit a board like the Singa Unikorn? Here's a repo with the models for exact dimensions if you're into it: https://github.com/evyd13/plain60-flex-edition

That looks like it might interfere with the Bluetooth module we are using but we'll give it our best shot!

Where does the battery live? Will you need to fully disassemble the board to replace it?

Any chance this can be modified to be compatible with the unikorn?

Awesome!
Look forward to a soldered version with split Spacebars 225+275, Split BackSpace, Stepped CapsLock,
split RShift (1-1.75-1, 1.75-1-1, and 1-1-1.75), 5x1u bottom row right mods.
Add under glow and you'd have the perfect 60 pcb!

We are using a rechargeable battery so you shouldn't need to replace it for years. You'll need to make sure the case you are using has the space for a battery underneath the PCB, we are asking vendors to test the PCB with cases they have. This should give us a list of cases that work

sounds like an interesting alternative to the keychron. So from my understanding, you just flash the chip on the keyboard with the github files and that's it? Will it work with any OS? (windows, iOs, macOs, android)
If yes then I will probably get that! I just want a good BT board that is not too expensive and has no software tail behind it.

It will come pre-flashed with a standard keymap, if you'd like to change that you can use an online tool on the zmk GitHub. It will compile the keymap for you and give you a uf2 file you can drop onto the board (double-tapping reset makes it show up as a memory stick).

So far we tested it with windows, android and ipadOS. We found absolutely no issues with pairing or using it on those devices

nice! I'm wondering, will there be a turn on/off button somewhere or will it turn on/off with a special key combo (eg strg+alt+1) or will it use the reset button (simple click, no hold)? Something that come into my mind after watching a keychron review.

The battery optimisation in ZMK is very good, after a period of inactivity it will go into a sleep state without the need to turn it off. It wakes up when you start using it again

Just a small update:
We tested the PCB in an ALU tofu case with an ALU plate and found no decrease in the range or signal strength!

More testing is still needed but it's looking very promising

Yes, you can connect the PCB to up to 5 devices and there is a hotkey to switch between them

That's awesome! I'm definitely in for at least 1, maybe more. I may rebuild all my 60s with this board.
Will it support wired mode also? This isn't a deal breaker for me but would be nice to have.

My end goal would be to have a lightweight MX version of a HHKB Pro Hybrid.

Yes it does! Check out this quick demo on switching between wired and Bluetooth.
