Dual-voltage supply ESP8266 Relay module

Post by Electroguard »

Some handy features of this item are:

Power it from onboard Mains supply or onboard low voltage regulator supply, or microUSB
'Dry' relay contacts have Common, normally Open, normally Closed, so can be used to switch MAINS or low voltages
Unlike Sonoffs, has full 4Mb flash
Unlike Sonoffs, offers access to all 12F pins, including ADC

Two for a tenner:
