Using a wireless module's excess processing capacity to replace the microcontroller can yield a cellular-equipped system that is smaller, more efficient, and much less expensive to produce. Not all wireless modules can be configured as application microcontrollers, but designers have many options. When making a selection, it's important to consider hardware specs, including processing power, memory resources, and power consumption. Designers also need to weigh software-programming options like an RTOS and software libraries. A module should have available a complete, easy-to-use development environment supported by device management services, for easier and less expensive long-term maintenance for deployed systems.
