Hello everyone, we are RAKKA, a team that is committed to creating interesting keyboard products. I want to introduce our new product to you, PomPomBoard, an ultra-low latency (~0.3ms), 8000Hz, magnetic switch pad.

Keyboards using magnetic switches may be unfamiliar to some, it uses hall sensors to detect the movement of the switch. Thus, the user can set the travel to any values they want. Furthermore, it is also possible for the user to adjust the travel while the user pressing the key. For example, we can archive this: If the user starts to press the key, trigger the key immediately instead of having to press a fixed length like a normal keyboard; stop triggering the key immediately when the user releases the key.

We have also succeeded in achieving extreme performance. PomPomBoard features ultra-low latency, stably detects key changes in a flash, in conjunction with the 8000Hz polling rate, less than 0.3 milliseconds latency is achieved.

The latency is tested with our hardware https://geekhack.org/index.php?topic=120238.

Hi there , im interested on this , but hopefully the price is somewhere within the price of the current soya

You mean Sayo O3C? It’s latency is around 3 to 4 ms and don’t have a easy to use remap and config GUI like me. It’s case and PCB are designed with the first goal of saving money. My cost is higher than his selling price
