Hi,
I'm very new to Arduino. I will teach a course on IoT and is considering using Arduino for device side development.
The device needs BLE and Wi-Fi features. I wonder if there is a combo part for this purpose.
Also, I notice some modules are offered as shield (with plug-in connectors) and some are barebone mini-boards. Just curious what people are doing with those barebone mini-boards (which seem significantly cheaper), i.e., how they are connected to Arduino boards.
Thanks in advance!
