Good for the price comes with led indicators. you can use it to control 4 different appliance. internal resistance of each relay is around 67 ohms. please note before you buy it is an active-Low device, which means you supply a low(zero) volt to the input pin to activate each relay.
This product is very good for those who want to start playing with electronics and programming and also to introduce children in this area. A lot of components in a box to keep all under control.
Impression:nice,Easy to use,portable;
