0xCB Helios Microcontroller

I picked up two Helios microcontrollers to revive my split keyboard after repeated ESD damage to previous controllers. With built-in ESD protection, they seem like the perfect solution. Too early to know how they’ll hold up long-term, but I’m hopeful. What surprised me most? A local Canadian store had them in stock—possibly the only one in the country—and shipping was fast and affordable. Super convenient to have this kind of niche gear right at home.

Very easy to flash.
