Scargill 18/02/2021

This board appears to have something for everyone. 220v AC in - OR 7-30v i- or even 5Vn - which makes it ideal for driving 12v lighting - via the 4 relays - without having to have a separate power supply for the ESP8266. Or of course mains control - and the relays are osolated with vommon, NO and NC lines made available.

Scargill Sorry about the spelling mistakes - the board is working a TREAT with Tasmota v 9.3.0.1 - I changed one relay link to remove an annoying power-up glitch - and I've already added an SSD1306 and a DHT22 - all documented on my blog. https://tech.scargill.net/h801-led-rgbww-strip-controller-and-banggood-4-relay-board/
