• Description
• Ultra. Low. Power. Arguably the best three words in the IoT world. SparkFun has teamed up with ARM and Dialog to provide you with this Qwiic WiFi Shield based around the DA16200 module. The DA16200 is a fully integrated WiFi module with a 40MHz crystal oscillator, 32.768KHz RTC clock, RF Lumped RF filter, 4MB flash memory, and an on-board chip antenna. With the addition of a Qwiic connector, multiple GPIO options, JTAG connectors for deep dive programming, and you've got everything you need to get your R3 layout device ready to set up your next IoT project.
• The SparkFun Qwiic WiFi Shield is ideal for door locks, thermostats, sensors, pet trackers, and other home IoT projects, thanks in part to the multiple sleep modes that allow you to take advantage of current draws as low as 0.2uA-3.5uA.
• Additionally, the DA16200 module's certified WiFi alliance for IEEE802.11b/g/n, WiFi Direct, and WPS functionalities means that it has been approved for use by multiple countries and using the WiFi Alliance transfer policy, each WiFi Certification can be transferred without being tested again.
• Note:Please be aware that logic voltage for the Qwiic DA16200 WiFi Shield is 3.3V only.
• The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can't hook it up wrong.
