SparkFun, Arm, Dialog Partner for Ultra-Low-Power Qwiic WiFi Shield Board

Offering sleep modes down to 0.2uA-3.5uA, this board could be just the thing you need for energy-harvesting IoT projects.

SparkFun has announced a partnership with Arm and Dialog Semi to produce an ultra-low-power Wi-Fi board for Internet of Things (IoT) projects built around the Arduino Uno form factor: the SparkFun Qwiic WiFi Shield.

"The DA16200 is a fully integrated Wi-Fi module with a 40MHz crystal oscillator, 32.768kHz RTC clock, RF Lumped filter, 4MB flash memory, and an on-board chip antenna," SparkFun explains of its latest board's central module. "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 [Arduino Uno] R3 layout device ready to set up your next IoT project."

Designed for low-power projects, the board offers a claimed current draw as low as 0.2uA-3.5uA while in the lowest of its three sleep modes. The on-board Wi-Fi processor supports 802.11b/g/n networks on the 2.4GHz spectrum with a 20MHz channel bandwidth, is compatible with 802.11s Wi-Fi Mesh networks, and offers WPA/WPA2/WPA2 SI/WPA3 SAE and OWE security compatibility.

"Additionally, the DA16200 module's certified [by the] Wi-Fi Alliance for IEEE802.11b/g/n, Wi-Fi Direct, and WPS functionalities [which] means that it has been approved for use by multiple countries," SparkFun notes, "and using the Wi-Fi Alliance transfer policy, each Wi-Fi Certification can be transferred without being tested again."

The SparkFun Qwiiic WiFi Shield is available on the SparkFun store at $19.95 before volume discounts, while a hookup guide offers instructions on its use.
