ASA is UV-resistant without any special additives, so the filament manufacturer shouldn't really matter. We always buy the cheapest one in white. text/html 2026-08-06T15:54:22+00:00 Anonymous (anonymous@undisclosed.example.com) http://wiki.opentrafficmap.org/en:hardware:setups?rev=1786031662&do=diff Hardware Setups OpenTrafficMap Node/Receiver USB + LAN IEEE 802.3af PoE * PoE jumper in position 802.3af * connected to an 802.3af PoE injector Passive PoE * PoE jumper in position passive DIY Receivers Mobile Setups FireBeetle 2 ESP32-C5 + W5500 + power bank + ZTE MU5001 HyperMobile 5G text/html 2026-08-06T15:57:18+00:00 Anonymous (anonymous@undisclosed.example.com) http://wiki.opentrafficmap.org/en:hardware:surge_protection?rev=1786031838&do=diff Surge Protection A receiver mounted outdoors (balcony, railing, mast) is usually powered via PoE, which means an Ethernet cable runs from outside straight to a switch or router indoors. Thunderstorms in the area can induce voltage spikes on such outdoor cable runs, damaging the connected network equipment. An Ethernet surge protector (surge arrester / voltage limiter) diverts these spikes to earth before they reach the devices inside.
