The SparkFun MicroMod DA16200 Function Board adds fully integrated Wi-Fi connectivity to any MicroMod project. Built around the DA16200 module with an Arm Cortex-M4F processor, it includes a 40 MHz crystal oscillator, 32.768 kHz RTC, 4 MB flash memory, and an on-board chip antenna — everything needed for IoT applications.

Three ultra-low power sleep modes with current draw as low as 3.5 µA make this board ideal for battery-powered IoT devices such as sensors, door locks, thermostats, and trackers. The DA16200 module is Wi-Fi Alliance certified for IEEE 802.11b/g/n.
