The ultra-low power,low voltage electronics of the WF280A is optimized for use in mobile phones, smart watches, PDAs, GPS navigation devices and outdoor equipment. The sensor module is housed in a compact 8-pin metal-lid LGA package with a footprint of only 2.0 × 2.5mm and 1.0 mm package height. Its small dimensions and its low power consumption allow the implementation in battery driven devices. With a low altitude noise of merely 0.1m and very low offset temperature coefficient (TCO), the WF280A offers superior performance and are perfectly suitable for applications like floor detection, health care as well as GPS refinement. The I2C interface allows for easy system integration with a microcontroller.
