today I will show you how to improve the COOLBoards (or quite any other ESP8266 based board) with this little mod.
- Your COOLBoard (or quite an
- 2 x 5 cm of wire
Step 1: Prepare Everything
Cut 2-3mm of isolation on each wire and put some tin on them (photo 1&2).
Put some tin on the end of the antenna on the microcontroller (see comment in photo 3).
Step 2: Solder and Test Everything
Solder one wire to the antenna and the other to the reset Button (photo 1).
Now let's check the signal. Photo 2 is before and photo 3 is after, you will have a 28% stronger signal (i will add db values later). Voila!
This cheap trick really improved the WiFi range of many of my ESP8266 projects ;)
Till next time!
