Let's start soldering and check if it is working:

To start soldering I first started to populate the small resistors and Diodes on the Top Layer. You might notice: I tried out some PCB art on the silk screen of the PCB.

After that I started to solder the Mikrocontroller:

And finally lets add The Lora Module and a Diode:

We can start programming the microcontroller now:-) I use this M5Stack Programmer and designed to PCB that you can plug and play on the pins on the far right side of the board (lapbeled with GD, G0, EN, RX,TX3V3)

et. Voila! : We got some light:
