What is not shown in this diagram is the processor to control all of this. This module is focused on the core IoT device. There will be a controller unit somewhere that contains RAM and CPU. It could be a developer unit like a Raspberry Pi, Arduino or BeagleBoard or others. IoT device developers should consider whether one of these open source kits would work to get an initial product to market. Based on market feedback the developer can determine if the board will continue to work or if it’s got too much RAM, not enough CPU and then determine what kind of tradeoffs need to be made on cost, size, certification requirements, performance and time to market.
