NanoboyPICO-V3-02 Example Programs
 
In order to run example programs you need to install Arduino IDE first if you have not installed.
 
 
You also need to install driver for CP2104 or CH9102F USB to UART bridge if you have not installed.
 
 
The NanoboyPICO-V3-02-JR is not shown on the ESP32 board list, but you can use it as a Feather ESP32 V2 board.
In Arduino IDE click Tools-->Board, then select the Adafruit's Feather ESP32 V2 for using the NanoboyPICO-V3-02-JR.

 

The NanoboyPICO-V3-02-JR board is pre-loaded with a test sketch and it will blink all output pins including the user LED at GPIO13.
Before soldering 2 male headers make sure that the NanoboyPICO-V3-02-JR board can blink the GPIO13 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.
NanoboyPICO-V3-02-JR assembly Instructions are similar to the SmallPICO assembly instructions.

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.
