These plates are custom-designed by nullbits to fit the SNAP 75% keyboard kit. They add additional support and strength to your SNAP build. They support all possible SNAP ANSI and ISO layouts, including split space, rotary encoder, and OLED display. They're perfectly sized for a Bit-C MCU and other Pro Micro MCUs. Build your SNAP with 3-pin plate-mount switches or hot-swap sockets without worrying about stability or alignment. **NOTE: This listing is only for the FR4 plates. SNAP kit sold separately.**
