STMicroelectronicsSTM32W108B-KEXT

The STM32W-SK and STM32W-EXT starter and extension kits are easy to use tools for the STM32W108xx microcontrollers. This family of microcontrollers integrates a 32-bit ARM® Cortex™-M3 microprocessor and a 2.4 GHz, IEEE 802.15.4-compliant transceiver. The kits demonstrate how effectively the STM32W108xx can be used in real IEEE 802.15.4 applications. The STM32W108xx kits provide demonstration applications and documentation which serve as a reference for creating your own applications and re-programming the STM32W108xx microcontroller. You can run the STM32W108xx kits in several ways (remote control/target, HID devices such as a mouse or keyboard and point-to-point applications), using the dedicated software libraries (ZigBee RF4CE, and Simplified MAC), as well as a third-party IDE and C compiler (IAR).

-32-bit ARM® Cortex™-M3 microprocessor
-2.4 GHz, IEEE 802.15.4-compliant transceiver
-Suitable for different types of wireless network scenarios such as:
  -Remote control and target networks (based on the  ZigBee RF4CE protocol stack) used for driving consumer devices such as TVs and set-top boxes, and HID devices such as a mouse or keyboard.
  -Point to point networks (based on a Simplified MAC library) used to address a basic IEEE 802.15.4 communication. This configuration enables customers to develop any protocol stack of their choice.
