What will you mostly use it for?
The Rhymestone wins for travel and modding due to its split, compact form and highlighted modding flexibility. The Treadstone48 has a slight edge for gaming and content creation because of its larger 50% layout and peripheral connectivity. For office work and programming, the decision is a tie, hinging entirely on the user's willingness to adapt to layers and their preference for split versus single-unit ergonomics.
Pick the KEEBD Treadstone48
- The Treadstone48's 50% layout provides more immediate key access than a 40%.
- Its single-piece design may be simpler to manage during gaming sessions compared to a split board.
- The vendor notes it can connect to the Rhymestone as a numpad, offering potential peripheral flexibility.

KEEBD Rhymestone Split Ortholinear vs Treadstone48: your questions
The Rhymestone is a 40-key split ortholinear keyboard, while the Treadstone48 is a 47-48 key single-unit keyboard with a symmetric staggered layout. The split versus unified design is the primary physical and ergonomic difference.
No. Both are DIY barebones kits. The Rhymestone includes two tactile switches for testing, and the Treadstone48 includes one. Both require you to source your own MX switches and keycaps to complete the build.
Both present similar challenges, requiring soldering of diodes and controllers. A customer review for the Rhymestone notes that LEDs are hard to solder and the guide is in Japanese. The Treadstone48 also requires careful modification of the OLED display. Neither is ideal for a complete beginner.
Yes. According to the Treadstone48 vendor description, it is based on the Rhymestone and the Rhymestone can connect to the Treadstone48 to function as a numpad or left-hand keyboard.
The Rhymestone kit supports RGB lighting via optional SK6812MINI LEDs. The Treadstone48 listing does not mention built-in RGB support, only an optional WS2812B LED strip.
Yes, both kits include Kailh hotswap sockets soldered to the PCB, allowing you to change MX-style switches without soldering after the initial build.
Both kits require Pro Micro controllers, which are not included. You must purchase and solder these controllers yourself to make the keyboards functional.
Yes. The Rhymestone kit includes two 0.91-inch OLED displays, and the Treadstone48 kit includes one. Both require assembly and connection via headers.
No. Both kits require you to flash firmware onto the Pro Micro controller. The vendor provides links to precompiled firmware, but a Rhymestone reviewer noted you may need to recompile it for different microcontrollers.
The kit includes components for two halves: two FR4 plates, two PCBs, two acrylic bottom plates, two OLED cover plates, a TRS cable, sockets, switches, OLED displays, hotswap sockets, diodes, standoffs, and screws.
The kit includes one FR4 switch plate, one PCB, one acrylic bottom plate, one OLED cover plate, sockets, a switch, an OLED display, hotswap sockets, diodes, standoffs, and screws.
The Rhymestone is a 40% keyboard and its split halves can be packed flat, potentially making it more portable. The Treadstone48 is a single 50% unit, which is still compact but not separable. Neither has a battery or wireless capability.
