We designed Connectino to be fully compatible with all Arduino Uno shields, so you can reuse your existing shields and easily port your projects to the Connectino. However, there is one restriction if you use the onboard Wifi module, shields using the UART on pins 0,1 cannot be used together with the WiFi module. If you do not use the WiFi module these pins are free to use.
Connectino can be set up to connect to an existing WiFi network. It also has a configurable access point for up to eight clients. For security reasons there is no routing between these these two interfaces, but you can connect multiple Connectinos to each other. That leads to the big advantage of being able to upload your Sketches via WiFi, without necessarily connect the USB to your computer. You won't need any line of code to configure the WiFi network, because you can do it all with the smartphone app or the web application instead. It is no problem to connect to networks with any up-to-date encryption standards.
With the full capable network interface you can realize whatever network application you want. The ATmega communicates over the serial interface with the IoT controller which handles all the network communication. This way you can easily connect multiple Connectinos over virtual "wires" (Netcat). It is possible to send mails and messages and the Connectino is able to communicate with cloud applications via MQTT, HTTP(S), REST and Websockets. We already build some examples in the form of tutorials for Amazon Web Services, IBM Watson, MS Azure and Arrow Connect. It's also easy to connect smarthome services like Alexa and Google Nest.
Connectino uses state of the art security mechanisms for the wireless network and internet access. Security technologies like WPA2 and TLS 1.2 are supported. The integrated HTTP server is secured by a configurable user access control management, where you can create different roles with different access rights. It is possible to add different client and server certificates and use HTTP Auth with challange response. Encrypted flash is supported as two-factor-authentication and JWT for even more security. That way it is also possible to create security based applications like electronic locks and access control systems.
