The AULA AG75 spreads its work across three microcontrollers, which AULA says cuts processing delay. That design feeds 256kHz full-key scanning, up to 2304kHz on a single key, and 8000Hz polling over its USB-C cable. Pro and Ultra alike are at Evetech.
Inside almost every keyboard there is a small chip doing all the thinking: reading keys, running lighting, talking to the computer. The AG75 carries three. AULA calls it a triple-MCU direct connection and says the split cuts processing delay. The phrase sounds like marketing, but the idea behind a triple-MCU keyboard is straightforward, and it explains how the AG75 can read its keys as fast as it does.
The AULA AG75 divides its internal work between three microcontrollers (MCUs) instead of one, which AULA says reduces processing delay. That arrangement supports 256kHz full-key scanning, up to 2304kHz when reading a single key, and 8000Hz polling over the USB-C cable. The AG75 Pro and AG75 Ultra both use the same design. Evetech carries the Ultra at R2,399 and the Pro at R2,399 in Shadow Grey or R2,799 in Armor Silver.
MCU stands for microcontroller unit, a small, self-contained computer on a chip. In a keyboard it has three broad jobs:
On a magnetic board, scanning is heavier work than on an ordinary one. Each Hall Effect sensor reports a position rather than a simple on or off, and the controller has to compare that position with your chosen actuation point and watch for the tiny upward movements that Rapid Trigger reacts to.
One chip handling everything has to take turns. While it is busy reporting or processing, it is not reading keys, and vice versa. Splitting the load across three controllers lets those jobs overlap, so scanning does not have to pause while other work happens.
AULA does not publish exactly how the three divide their tasks, so the best way to think of it is capacity. More processing headroom is what allows the rates AULA quotes for the AG75:
There is nothing to configure. The MCUs work in the background from the moment the board is plugged in; your settings live in AULA's browser-based web HUB, where you tune actuation, Rapid Trigger, SOCD, DKS and the rest.
Where the design earns its keep is in those features. Rapid Trigger on the AG75 works at 0.001mm precision with a true zero dead zone, which means the controllers must notice extremely small movements quickly and act on them. Dense, fast scanning is what makes that practical. The same applies to DKS and Multi-Point Trigger, which assign actions at different depths and need accurate, frequent position readings.
The triple-MCU arrangement is shared by every AG75, whether the Frostcore-equipped Pro in Shadow Grey or Armor Silver, or the Eight Treasures Ultra in Battle Shine Orange. Pick your edition on switch and colour; the electronics are the same.
Evetech carries the AG75 range under gaming keyboards, where it has a 2 Years Local Warranty, and it is worth comparing against the buyer favourites in keyboard best sellers. Evetech's product pages list the price.
