Pin defines are: - For Pico define board pins and the default LED pin (WL_GPIO25). - For Pico-W define board pins, external pins and the default LED pin (WL_GPIO0). - For the Nano-RP2040, define board pins, external pins and the default LED pin (GPIO25) - For all other boards, the pins.csv defines the LED pin (if any) for backwards compatibility with code that assumes there's always an LED pin.

Network Example
To use network / socket based code, connect ethernet port to network with DHCP running:
>>> import network
>>> nic = network.WIZNET5K()
>>> nic.ifconfig()
('192.168.0.18', '255.255.255.0', '192.168.0.1', '8.8.8.8')
>>> nic.dhcp(True)
('192.168.0.10', '255.255.255.0', '192.168.0.1', '192.168.0.1')
At this point standard network communications libraries should work.
