KAPPA5

KAPPA5 is an ESP32C5 dev board designed to show off the dual band chip and provide a starting point for building projects with Espressif's first 5GHZ chip.

WHY

I designed KAPPA5 because I have always used ESP32s but not haveing 5GHz support has limited their use in areas where 2.4GHz is too congested.
