What Is IoT PCB?
An IoT PCB (Internet of Things Printed Circuit Board) is the foundational hardware platform that powers IoT devices.
It integrates sensors, communication modules, power management systems, and processing units into a compact circuit board.
In simple terms, IoT PCBs allow devices to:
- Sense their environment
