Open up our compact ALT keyboard, and you’ll find its PCBA: the assembled printed control board, and the party responsible for many of the ALT’s crucial functions. It’s among the best in its class—and now, it’s available to buy as a standalone component. Home to all electronics on the ALT, the PCBA handles everything from custom key commands to custom RGB settings. It also houses the ALT’s hot-swappable switch sockets, which allow users to change switches without soldering; as well as the RGB LEDs themselves, which create over 16 million unique colors for brilliant backlighting. Read reviews for the ALT, and you’ll see that the PCBA performs these functions and more with exceptional execution. If you want to build a compact keyboard that does the same, this is a must-have component.
