+### Connection
+Vcc - 3,3V  
+TX - RX  
+RX - TX  
+GND - GND
+
+### Additional Information
+A low pulse on GPIO12 switches the relay on, a low pulse on GPIO5 switches it off.  
+I have solved the 'pulse issue' by setting GPIO12 to always 0 (as LED) and works fine.   
+More Infos can be found here: [#1988](https://github.com/arendst/Sonoff-Tasmota/issues/1988).
