2.3.5 Automatic bootloader on NINA-W10 EVK
The “esptool.py” flashtool supports automatic entry to the bootloader on the NINA-W10 EVK
without pressing the BOOT button and RESET the module. To use this functionality, you need to
connect the following pins:
• RESET to IO19 (CTS)
• IO0 (IO zero) to IO26 (DSR)
The jumpers CTS (J14-8) and DSR (J14-7) should also be removed so that they do not interfere.
☞ It is not possible to use the Hardware Flow control or the DSR signals on the UART while using
this setup.

2.4 Arduino support for NINA-W10
It is possible to use Arduino electronics platform on the NINA-W10. The Arduino platform and open
source community provides the possibility to access a lot of third party hardware such as displays
and sensors.
2.4.1 Downloading the Arduino IDE
Windows, Mac, and Linux environment are supported. The example below uses the Windows
environment. Download the Arduino IDE using the URL - https://www.arduino.cc/en/Main/Software.
