More Details from Polarity Works
Introducing the Polarity Works Common Keyboard Platform (CKP). While developing this we had one goal in mind, design the best series of wireless PCBs on the market. Starting from scratch we listened to feedback from the users of the BT60 V1, added extra features, more layouts, more sizes as well as the thinnest battery ever seen in a keyboard for near 100% case compatibility.
Case compatibility to be rather challenging, especially on some 65s and 75s without a battery well, so we hunted the world for a battery slim enough to fit into almost all cases and came up empty. But we decided to create it! The Filament Power 1200 battery has a 1200mAh capacity and comes in at the THINNEST lipo battery ever put in a keyboard at just under 1.4mm thick. it won’t decrease your battery life, with all lighting off expect the several months you’ve come to expect from our boards.
The zmk-config repos for these boards are available here: https://github.com/PolarityWorks/zmk-config-ckp
I'm not in Canada, can I get these in my country?
Yes. Check out Polarity Work's Vendor list for the other vendors.
(Unfortunately my carriers don't allow the shipping of Li-ion batteries internationally, so I cannot send these outside of Canada)
