Makcu — catalog of mouse and keyboard control modules.

What a Makcu module is for

Makcu is the board through which a second computer drives the mouse and keyboard of the gaming PC. To the gaming machine they are ordinary USB devices: the signal arrives down a cable from a separate board, not from software running inside the system. That is what stops a DMA card setup being read-only — the card reads memory, the module handles input.

How the modules here differ

• The Makcu board on two ESP32-S3 modules — the basic option. Two N16R8 modules (16 MB flash and 8 MB PSRAM each), 1000 Hz polling, three USB ports and a CH343 UART bridge up to 4 Mbit/s. The firmware is open source and the board is flashed and set up once.
• Makxd — the updated Makcu: the same role in the setup, finer configuration and a wider feature set.
• Ferrum One — a finished input device with polling up to 8K and software of its own, a full replacement for the KMBOX B+ Pro. The option for "plug it in and play", with no flashing and no hunting for cables.

How to choose

• What you are connecting. A mouse alone or a mouse and a keyboard — that decides how many ports and cables you need.
• Whether you want to flash it yourself. Makcu and Makxd are flashed by hand, step by step in the guide; Ferrum One works out of the box.
• Polling rate. 1000 Hz covers what most mice can do; more is worth it only if the mouse itself goes higher.
• Cables. One per device plus one to the second computer — the Makcu board ships with three USB cables.

What else the setup needs

The module is one part of a chain. A DMA card reads memory, a fuser carries the picture from the second computer, and that second computer is usually a Mini PC. If you would rather not check compatibility yourself, there are assembled and tested kits. If you build your own hardware, look at the development boards.

Flashing and setup

The board arrives unconfigured: you flash it, plug the mouse and keyboard into its ports, and connect the module itself to the gaming PC and to the second computer. The order of the steps, the firmware files and the usual mistakes are covered in the Makcu flashing guide. The source is open, so the firmware can be built by hand.

Delivery and warranty

Boards are tested before they ship and sold with a warranty. We ship across Russia and the CIS; the options and timings are on the payment and delivery page.
