Designed by Duck0113, who also designed other boards such as the Light Saver, Viper, Eagle, Octagon and Orion.
The Raven is a pure 60% board while the Sidewinder has HHKB-style blocked corners. Both are MX and Alps compatible. A stainless steel switch plate is required for Alps compatibility. MX users may choose the aluminum plate or no plate at all. Stabilizers are NOT included with the kits. They may be purchased here on PrimeKB or from your favorite enthusiast keyboard vendor.
