The Q9 is Keychron's 40%, a tiny all-aluminum board with no number row at all. Numbers, symbols and the function keys live on layers you set in VIA. Keychron listed it in August 2022. For its size it keeps a small arrow cluster in the bottom-right corner, and the knob version adds an encoder at the right end of the top row. Inside it's the Q recipe, with a gasket-mounted steel plate, silicone pads between the case halves, south-facing RGB and hot-swap sockets for 3- and 5-pin MX switches, and a built one weighs about 1 kg. The Q9 Plus splits the space bar so your thumbs get two more keys to program. A 40% takes real relearning, so try a 40% keymap on your current keyboard first if you've never used one.

Versions
The standard Q9 has a single space bar and came with Gateron G Pro switches, with or without a knob. The Q9 Plus splits the space bar into three keys, a function key and two spaces you can remap, and came with Keychron K Pro switches and a knob. ISO was sold only as a barebone with no switches or caps. QMK treats the Q9 and Q9 Plus as different boards, so flash the matching file.
Most of the keyboard lives on layers, so a used Q9 may arrive with a past owner's keymap that makes no sense to you, which a factory reset or VIA fixes. Check that the board is the Q9 or Q9 Plus you expect, since their space bars and firmware differ.

Buying guide
We'd buy the open-box Q9 from a US seller at $182 delivered, less than half what the boards from Japan ask, once the seller sends photos of the board itself, since the listing shows only the box. Only four Q9s are listed, so the $370–500 band is one Japan dealer's asks and isn't a market read. The other three come from risingsungaming with $120 shipping each, a standard Q9 titled unused and two Q9 Plus boards, which split the space bar into three keys and take their own QMK firmware file. One Q9 Plus is titled JP, which means a Japanese layout, so a US buyer wants one titled US layout. A 40% puts the numbers and symbols on layers, so expect a past owner's keymap and plan to reset it in VIA.
$182.06est. delivered
The only US listing, an open-box Q9 at $182 delivered from a 100% seller, against $434–516 for the boards from Japan. The photo shows only the box, so ask for pictures of the board, its caps and the cable before you buy.

A Q9 Plus Q9L-M3 with the knob, titled tested and US layout, and the photo shows it boxed with the quick start guide. At $482 delivered it costs far more than the US board, so it's the one for buyers who want the split space bar.
