Easy Electronics ESP8266 NodeMCU Based 4-Channel Relay Board Micro Controller Board Electronic

Good performance

Came with bare minimum packaging, but somehow the board survived. Uses few of the most inappropriate shared-pins on ESP8266 for relay control - essentially a very poor design using shared pins. There is no response or support from the seller (EasyElectronics) on how to use the board - It isnt difficult to figure out, but I'd recommend to buy ONLY if you really know what your are doing! Its probably better off buying ESP8266 and a 4-Channel relay board seperately and wiring it as per your needs-This board serves no additional purpose other than avoiding connecting 4 wires between an ESP8266 module and 4-Channel Relay module.

Having made a number of modules using arduino uno, relays , wi-fi module and a combination of Wemos and relay module, this ready made board made life so much simpler for me. There was no soldering whatsoever required on the board and it worked like a charm.I received the item within the promised time and it was very well wrapped and put into a transparent plastic box. I have to say the packing was of a very good standard. I only wish I had come across this module much earlier while attempting to automate the remaining rooms of my house.A much recommended buy for any DIY enthusiast and the price is very reasonable compared to how much I would have spent had I bought the individual items and set it up.

The PCB board with relay was in good quality. But nodeMCU was really bad.NodeMCU came with the board was absolutely useless. The pins in nodeMCU was rusted. I have attached the photos of nodeMCU. It gets very hot in just 1 minute of usage. I really needed to buy another nodeMCU. Otherwise, PCB was in good condition.

This thing is as good as expected. Plug it into a mini usb port and it starts working. It is coded already for the switches to go on and off in series to show that it works. I added my own code and now my room switchboard is wifi controlled. Very good quality product.Note: This needs to be coding to work automatically over wifi. Buy only if you are an enthusiast.

Very good product. Value for money. I am very happy with product i received. Before purchase of this product. I have purchased similar product with other make, it was found not good, so I returned that one and ordered this one. Really awesome product. Packaging was also amazing.

The NodeMCU is working fine. The only issue is that when I tested the relays after receiving the product, I realized that one of the relay board doesn't work.

The media could not be loaded. The PCB board and Node MCU is very good quality.This thing is as good as expected. Plug it into a mini usb port and it starts working. It is coded already for the switches to go on and off in series to show that it works. Very good quality product.👍👍👍👌👌
