# ESP32-C6 DevKitC-1 board (ESPA_V2 hardware)
#
# Key differences from ESPA_V1 (ESP32-S3):
# - Uses Hardware CDC (HWCDC) for USB serial instead of native USB CDC
# - Only has UART0 and UART1 (no UART2), so spa serial uses Serial1
# - Single WS2812 RGB NeoPixel LED on GPIO10 instead of 4 separate LEDs
# - General purpose button on GPIO21 (GP_PIN) for future functionality
#
# USB Serial Configuration:
# - ARDUINO_USB_CDC_ON_BOOT=1: Routes Serial to USB CDC
# - ARDUINO_USB_MODE=1: Selects Hardware CDC (HWCDCSerial) over native USB
#
# Deferred Initialization:
# Global objects (SpaInterface, MultiBlinker) must defer hardware init to
# setup() because ESP32-C6 constructors run before Arduino framework is ready.
