I made a battery shield for my X-Project. Now the World Clock could be on my desk without power line!
As what you have seen:
X-OLED is on the top, X-8266 is in the middle, X-Battery shield is at the bottom with a small 400mah Li-battery.
I also developed a lot of shields like DHT11,Buzzer,Button,WS2812b... for X-project.
This time I only test this battery shield.
Step 1: X-Project Member
In my project. D1 is SDA,D2 is SCL.
Connection is very easy.
All the members of X-Project have the same size and the same pin map.
The only things is you need to do a little change to code.
Please follow this project:
There is a world clock example in this project.
Here I changed #include "SSD1306Wire.h"-> #include "SH1106Wire.h"
Do not forget fill WiFi name and password.
