Keychron New S1 QMK Custom Mechanical Keyboard


Keychron S1 is the first 75% layout all-metal low profile custom mechanical keyboard. With its all-metal ultra-slim CNC machined body, QMK/VIA support, and low profile double-shot PBT keycaps, the S1 gives you a high-end typing experience, a unique design setup, and endless possibilities. One of a kind.

On the heels of the new Keychron K3 Pro, comes a similar yet different premium low-profile keyboard from Keychron. If you’re confused, here’s some details on the differences between K series, K Pro series, and S series.

Short version: versus the K3 Pro, the S1 is wired only and the aluminum body has a steel plate — heavier and less likely to flex.

Not many reviews, but overall the few seem positive:

That means the Keychron S1 is more focused on being high-quality than feature-rich. It’s not wireless, and it’s not hot-swappable as standard, meaning you can’t change the switches on its entry-level model without a soldering iron. But what you _do _get is an aluminum construction, double-shot PBT keycaps, a 1,000Hz polling rate, and full remapping support with the excellent VIA keyboard software.

The new PBT Keychron keycaps are a great upgrade. The won’t get as oily and they feel a decent amount better. Their concavity I enjoy more than the K3v2, those felt like they had no top and bottom”, it was easy for me to not know how vertical I was on the board.
The K3v2 is exactly the same height as the S1. I had heard otherwise, they’re the same. Mech Mini is definitely taller, I find it only mildly noticable.
I really like how the S1 feels. It’s solid. I’m keeping it.

A few weeks back, I was sure the K3 Pro was going to be my next keyboard. Now I’m heavily leaning towards the S1.
