$99 EFR32xG22 Wireless Gecko Starter Kit Offers Low-Cost Zigbee Development Platform

Silicon Labs has just launched a low-cost Bluetooth, Zigbee, and proprietary wireless development kit with the $99 EFR32xG22 Wireless Gecko Starter Kit (WSTK).

This WSTK includes two +6 dBm radio boards, matching network, and PCB antennas for +6 dBm output power in the 2.4 GHz band, as well as on-board J-Link debugger. Previously you had to purchase the $479 EFR32xG21 Wireless Gecko Starter Kit to get access to the Zigbee SDK in order to get started with development, and the new starter kit makes it possible to get access to the same software resources and documentation for around $100.

Simplicity Studio EmberZNet PRO Zigbee SDK
EmberZNet Zigbee SDK in Simplicity Studio – Click to Enlarge

Development is done using Simplicity Studio where you’ll be able to install Bluetooth SDK, Bluetooth Mesh ADK and SDK, EmberZNet (Zigbee) SDK, and
Flex SDK as explained in the Getting Started Guide.

This announcement may also be relevant to Sonoff ZBBridge WiFi to Zigbee gateway that was recently launched for just $16.90. The gateway is based on Silicon Labs EFR32MG21 Gecko Series 2 Cortex-M33 WiSoC, and people have started to reverse-engineer the gateway to port TASMOTA open-source firmware and at least one of the developer purchased the board to get a license for the Zigbee SDK.

Silicon Labs EFR32xG22 Wireless Gecko Starter Kit can be purchased for  $99 on distributors like Digikey, Arrow, or Mouser. Further information may also be found on the product page.

Thanks to Andreas for the tip.

Those who are interested in that started kit might also be interested in buying article SLWRB4180A for around $49 at the same time as that is the matching EFR32MG21 (EFR32 Mighty Gecko Series 2) based high-power (+20 dBm) radio board for that dev board kit.
SLWRB4180A is the same EFR32MG21 radio board that is included in the $479 EFR32xG21 Wireless Gecko Starter Kit, and EFR32MG21 is same type of chip used in Sonoff ZBBridge Zigbee Bridge.

Anyone knows if the EmberZNet (Zigbee) SDK license that comes with this kit is tied to the processor family?
I have a couple of Thunderboard Sense 2 (EFR32MG12) that I’d like to put Zigbee on them as well.

It has been confimed that the license is not restricted, so buying any kit does give you access to all Zigbee stack versions for all chips families any series. With the obvious limitation that you can not run Silabs Zigbee stack on chips that do not support Zigbee at all.

Thanks for confirming. Just ordered it from Mouser.

Just confirming that I was able do compile and load the EmberZNet on the Thunderboard Sense 2.
