Assembled controllers, as you may have guessed, are where we pick and choose the various components that we need to build an efficient and a power-optimized sensor node.
As we have seen earlier, their setup would look like this:
Now, this is where things get interesting. Depending on the compute needed, the power requirements, and the functionality, we can choose a combination of the microcontroller and the network module.
Here the network module acts as a slave to the microcontroller.
