# Romu specific: Check if RGB LED is accessible via PWM or digital
# Assuming direct GPIO control for RGB (adjust pins per schematic)
# Note: Romu might use WS2812, requiring neopixel library. 
# This example uses simple digital IO for demonstration.

# Placeholder pins for Romu buttons
btn = machine.Pin(12, machine.Pin.IN, machine.Pin.PULL_UP)
