Open source keyboard lets you swap parts like magnetic Lego bricks

MIT freshman Nathan Alspaugh developed Keybytes, an open-source modular keyboard in which each key contains a RISC-V microcontroller and connects to neighboring keys through pogo pins. He estimates a full-sized keyboard would cost around $900 at current assembly costs, and says he may sell units after improving and finalizing the designs.

Analysis

This is a maker-project signal, not a commercial launch. Its investable implication is mainly a useful boundary case: per-key electronics and interconnects can make customization technically feasible while making unit economics unattractive at consumer scale. More modules also mean more assembly steps and potential connection points to validate, so the concept’s repairability and flexibility must outweigh added cost and reliability work before it challenges conventional keyboard designs.

For Cherry SE (C3R), the use of Cherry MX switches is at most an indirect compatibility reference; this project does not establish incremental switch demand, licensing, or a commercial relationship. Any revenue effect would be immaterial absent scaled production. Peripheral incumbents likewise face no near-term competitive threat. A broader, conditional opportunity would accrue to PCB assembly and component suppliers only if similar modular designs move beyond hobbyist builds.

Days: no durable catalyst or earnings signal. Over 1–3 months, watch for finalized designs, repeatable builds, and evidence of buyers beyond the open-source community. Over 6–18 months, meaningful adoption would require lower assembled-board costs and evidence that users value reconfiguration enough to pay for it. The contrarian point is that the novelty may attract attention, but the stated cost hurdle likely matters more than technical ingenuity. The thesis changes only with credible production economics and demonstrated demand; absent those, no trade is warranted.

Key Decisions for Investors

• Do not initiate a C3R position on this project; the switch reference does not support a material revenue or earnings revision.
• Treat any broader keyboard-peripheral read-through as a watch item, not a short thesis against Logitech, Corsair, Razer, or other incumbents.
• Revisit only if the project or comparable designs show repeat purchases, commercial distribution, and materially lower build costs; verify production volumes and component economics before assigning supplier exposure.
