LoRa wireless remote water tank and pump controller (esp8266) Server PCB assembling

Now we must assemble the Server PCB, and you can get It without additional cost on PCBWay.


ReWaL: Server PCB PCBWay

The prototyping and testing

As usual, I prototype the PCB on Fritzing, and I’m going to mill with my Cyclone PCB Factory.

If you want to build It, you can refer to this Tutorial, “CNC Cyclone PCB Factory“, then the guide to prototype with the CNC “Milling PCB tutorial“.

I think the milled PCBs are very artistic :P.

Assembly

To assemble, you can refer to the silkscreen of the PCB, and I do It quite verbose.

And I also create a video of the soldering phase

Here is the result of your work

Then, we must start to assemble the components, the LEDs, switch, display, WeMos D1, and EByte E32.
