#### More About Notecard Connectivity
22+
23+
The Notecard is a wireless, secure abstraction for device connectivity, that can
24+
be used to enable _ANY*_ device with I2C, or UART, to connect to the Arduino IoT
25+
Cloud via cellular, LoRa, satellite or Wi-Fi (including the devices listed
26+
above)!
27+
28+
As a result, the STM32 architecture has now been added to this library. If you
29+
have an STM32 device, you are now able to connect it to the Arduino IoT Cloud by
30+
using a Notecard to provide a secure communication channel.
31+
32+
> \*_Unfortunately, the AVR architecture is not supported by the Arduino IoT
33+
> Cloud library. Therefore, those devices are ineligible for use with the
34+
> Notecard._

### How?
2037
1) Register your Arduino IoT Cloud capable board via [Arduino IoT Cloud](https://create.arduino.cc/iot) (Devices Section).
