+## ARDUINO NANO 33 IOT
+
+#####  ARDUINO NANO 33 IOT board
+
+1. Install Arduino Nano33 IoT board support into your Arduino IDE.
+
+    - Open Boards Manager from Tools > Board menu and install arduino nano 33 iot platform 1.8.11 or later
+
+    - Select your Arduino Nano 33 IoT board from Tools > Board menu after installation
+
+2. Open the `iothub_ll_telemetry_sample` example from the Arduino IDE File->Examples->AzureIoTHub menu.
+
+3. Update Wifi SSID/Password in `iot_configs.h`
+
+- Ensure you are using a wifi network that does not require additional manual steps after connection, such as opening a web browser.
+
+4. Update IoT Hub Connection string in `iot_configs.h`
+
+5. Configure board library using the automation script and `python3`. If you choose this method you can skip step 6.
+    - Clone or download this repo: `git clone https://github.com/Azure/azure-iot-pal-arduino.git` , navigate to the downloaded sub-folder: `cd azure-iot-pal-arduino/build_all/base-libraries/AzureIoTHub/src/scripts` , and check that the script `automate_board_config.py` exists in this location. If this folder or script cannot be located, download the script [directly](https://raw.githubusercontent.com/Azure/azure-iot-pal-arduino/master/build_all/base-libraries/AzureIoTHub/src/scripts/automate_board_config.py).
+    - Run the script E.x.: `python3 automate_board_config.py` and select appropriate options.
+    - Note: if you update or reinstall your board library in Arduino you will need to run this script again.
+
+6. Navigate to where your arduino nano 33 iot board package is located, typically in `C:\Users\<your username>\AppData\Local\Arduino15\packages` on Windows and `~/.arduino15/packages/` on Linux
+
+	- Navigate deeper in to `hardware/samd/<board package version>/` where the `platform.txt` file lives.
+
+	- Copy the [`platform.local.txt`](https://github.com/Azure/azure-iot-arduino/blob/master/examples/iothub_ll_telemetry_sample/ArduinoNano33iot/platform.local.txt) file from the `ArduinoNano33iot` folder in the sample into the same folder as the `platform.txt`.
+
+	- Alternatively, or for later versions of the Board Package, add the define `-DDONT_USE_UPLOADTOBLOB` to `build.extra_flags=` in `platform.txt` or a `platform.local.txt` that you create.
+
+7. Run the sample.
