UPDATE 16/06/2021:
After lots of
testing and iterating, we are happy to announce the BT60 is
now in production! There are a total of 480 PCBs in the
first batch, half are hotswap and half soldered. They will
be heading out to retailers in the next month. Here’s the
vendor list and prices:
Upgrade Keyboards (USA) -
$55-65

Keygem (EU) - 55-60

Mechboards (UK) - £60-65 (LIVE)

Hotswap Features:
- Bluetooth connectivity (Works in metal cases!)
- Connect to up to 5 devices
- Weeks of battery life (1200mAh battery included 4x30x80mm)
- Fits into most 60% cases
- Standard ANSI layout
- Solder pads for optional split back space
- USB pins broken out
- ESD Protection
Soldered Extra Features: - Encoder support
-
Lots of layouts (no room for a split space)
We tested the range in a TFV2 with a brass plate and found it to be about 30m in open air.
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.

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.
