I only just now learned that Banggood has a US-based ecommerce site – no more waiting weeks for a DS3231 RTC, etc. Selection is lower, but seems to be nearly identical in price, maybe a tiny bit higher, but 4 days versus 6-ish weeks, totally worth it to me. Good to have another source for components.
Sadly, looks like their only RGB leds are single ws2812b boards, didn’t find any strips. I’ll have to rummage a bit more.
