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.
