An Epic Core Inside
A powerful ARM architecture MCU WB32F3G71RCT6 equipped with 256KB Flash will provide more flexibility for developers. The polling rate is 1000 Hz on 2.4GHz and wired modes right out of the box, which makes the latency hardly noticeable even in competitive games.

Hot-Swappable (Optional)
Keychron also provide a hot-swappable version for your choice, which means you can customise your typing experience without soldering, pop them in and it's done.
Every detail matters for a personalised typing experience, that’s why they give you the power. You can hot-swap every switch on the J2 with almost all of the 3-pin and 5-pin MX style mechanical switches on the market (including Cherry, Gateron, Kailh, Panda, etc.) without soldering. You can customise your own typing experience in seconds.

Their transparent top housing maximises light transmission, delivering brighter, more consistent RGB backlighting while ensuring smooth and reliable performance for years to come.
