The CH552-36 is a 36-key split keyboard designed by Richard Goulter. It takes inspiration from TeXitoi's KeySeeBee.
I liked the look of the "show the components" along the side of the PCB, as well as the look of the (mostly) SMD components, and the idea of just having a keyboard that's the PCB & switches – richardgoulter.

The design has a few properties that reduce the cost: just like some previous models by the author, it uses the cheap CH552T MCU, and the PCBs are smaller than 100x100mm. (The boards aren't reversible though; "the design is neater for not being reversible".)
The switches are 5-pin MX-compatible, which saves the need for a plate.
The repo contains a tenting stand too:

Since it uses the CH552 MCU, the keyboard uses semickolon's FAK firmware, which uses the Nickel configuration language to declare keyboard and keymap definitions.
