NanoboyS3-JR Example Programs
 
In order to run example programs you need to install Arduino IDE first if you have not installed.
 
 
The NanoboyS3-JR is not shown on the ESP32 Arduino board list, you can use it as the ESP32-S3 DEV board of Espresssif Systems
 (the ESP32 chip maker).

In Arduino IDE click Tools-->Board, then select the Espressif's "ESP32S3 Dev Module" for using the NanoboyS3-JR.

After selecting the board type, make sure that the USB CDC On Boot is enabled.  This will allow the serial monitor to work when your sketch is running.

The NanoboyS3-JR board is pre-loaded with a test sketch and it will blink all output pins including the user LED at GPIO36.
Before soldering 2 male headers make sure that the NanoboyS3-JR board can blink the GPIO36 LED with your Arduino IDE.
If it can't, troubleshoot the problem first before going further.
If you can't Blink-A-LED before soldering, you won't be able to Blink-A-LED after soldering.
 
 
After you successfully ran the Blink-A-LED you can assemble it now.
NanoboyS3-JR assembly Instructions are similar to the SmallPICO assembly instructions.

All example programs are tested with Arduino IDE 2.2.1 and Espressif 3.0.0a

Blink-A-LED   
Test RGB  
0.96" OLED display  
2.2" TFT display  
WiFiscan to test whip ANT  
Battery level test  
Deep Sleep current test 12uA
 
 
We added a blinking LED to indicate the start of a WiFi scan. After testing many different antennas we feel that the whip antenna offers a high signal strength and wide coverage. We added both whip antenna and UFL antenna on this board. You can use either one.
You can compare it with all other ESP32 boards that you may have, you will find out how good the whip antenna is.
