user71100: Just starting to learn about Arduino and IoT. I'd like to know what the Arduino hardware options are to try the following:

Use FreeRTOS as SO
WiFi and BLE connectivity
Solderless board
Test OTA features
Experiment integration with different IoT Cloud platforms e.g. Azure IoT Hub
Build custom IoT devices


user61722: There are many options; which one is "best" for you I leave up to your own research, that could start here:
There's a list of Arduino's based on the SAMD21 that are supported by the FreeRTOS_SAMD21 library here; pick any one with WiFi and BLE.
There are probably a zillion clones out there that could also do what you want, and there is also a FreeRTOS port for the ESP32 (ESP-IDF FreeRTOS, and maybe other ones as well).
