nRF7002 Expansion Board adds WiFi 6 to Nordic Thingy:53 devkit

Nordic Semi keeps adding more nRF7002 WiFi 6 boards with the launch of the nRF7002 Expansion Board adding WiFi 6 connectivity to the Thingy:53 IoT prototyping platform and transforming it into an all-in-one wireless devkit with Matter, Bluetooth Low Energy, Thread, and WiFi 6 support.

The new “nRF7002 EB” board follows the nRF7002 DK development kit combining the nRF7002 WiFi 6 with nRF5340 multiprotocol wireless SoCs, and the nRF7002 EK evaluation kit in Arduino UNO shield form factor adding WiFi 6 to existing Nordic development kits.

nRF7002 Expansion Board specifications:

  • Chipset – nRF7002 Wi-Fi Companion IC with support for features such as OFDMA (Orthogonal Frequency Division Multiple Access), Beamforming, Target Wake Time, and SSID-based locationing
  • Antenna – 2.4 GHz / 5 GHz ceramic antenna
  • I/Os
    • Castellations for all pins on nRF7002
    • Thingy:53 expansion connector with SPI and a 3-wire coexistence interface to allow seamless coexistence with other wireless protocols
  • Misc – SWF port for RF measurements
  • Mechanical
    • Thingy:53 Plug-in form factor
    • Perforations along the neck of the Thingy:53 specific connector to solder the nRF7002 EB to other boards

That’s where the expansion board goes…

On the software side, the nRF7002 Expansion Board is supported in the nRF Connect SDK and an Edge Impulse Wi-Fi sample allows the Thingy:53 to upload data samples to Edge Impulse studio directly using Wi-Fi, instead of relaying them via a Bluetooth LE-connected smartphone. Hardware documentation can be found in the infocenter and a guide to get started with the nRF7002 EB using the nRF Connect SDK is available on the developer’s website.

The nRF7002 Expansion Board is available for about $10 on  Digi-key, Symmetry Electronics, and other distributors. Additional information may also be found on the product page.
