MAKCU vs YSC vs NB Pro vs Ferrum

All four are mouse and keyboard passthrough controllers: your devices plug into them, everything passes through to the PC, and the controller handles input in its own hardware. Here is how they differ.

MAKCU

The most affordable choice. Automatic mouse passthrough with no setup, up to 1000 Hz with no added latency, and free open-source firmware you can build on.

YSC

The most affordable 8000 Hz option, with its own USB stack and low-level firmware. It speaks both the COM-port protocol and kmboxnet, and also passes game controllers through.

NB Pro

The high-end pick: a 64-bit processor (700 MHz, up to 1.2 GHz), 128 MB of memory and storage, a 2.8″ colour screen and every feature of the KM Net and KM B versions.

Ferrum

Up to 8000 Hz and every standard Kmbox B+ Pro command, so it drops in where that is already supported, plus a custom API. Firmware comes pre-flashed.

They pass standard USB mice and keyboards through, and your device's own software keeps working.
