Please excuse my ignorance, but an Arduino is a piece of hardware that I can buy. Azure RTOS is an operating system that runs on embedded systems. Googling "Azure RTOS hardware" doesn't yield much. What do I need to search for to buy hardware to run Azure RTOS?
Early days but I am designing a solution to read an https://m-bus.com/ (water) meter, perform some calculations and then through a banking API, send a payment to a utility company. I want the device to be as lightweight (and cheap) as possible, hence exploring Arduino over a Raspberry Pi, however as my day job is an Azure Engineer, Azure RTOS has sparked an interest. This will be a one-off. I'm not planning on taking it to market. I should probably mention both the Arduino and Raspberry Pi have M-Bus shield/hat that physically connects (M-Bus supports wireless) to the meter. I guess any Azure RTOS compatible device will need M-BUS receiver hardware.
What is the cost of Azure RTOS-compatible hardware? An Audino costs about £30.
What is the cost of Azure RTOS? as I read that it requires licensing?
Thanks
