The STM32WB Feather Board is a development board based on the Adafruit Feather standard with the STM32WB Bluetooth SoC at its core. This board specifically uses the STM32WBCGU6. It includes all the basic functionality you need to get up and running quickly. The board was designed to be integrated into a larger design and thought has been put into making this device efficient at low power.

ST's new line of IoT SoCs is exciting. Instead of requiring separate chips for the microcontroller and radio, these new SoCs integrate everything together in a single chip. This has obvious size advantages, allowing smaller designs. Another major advantage is power efficiency. With much tighter control of the radio, the SoC can achieve lower power sleep states.

This board is designed to let you get started quickly with the STM32WB. It has everything you need to just plug in a USB cable and go. You don't even need special programming hardware, though the board has a standard SWD connection for debugging. Here's a list of its features.

• STM32WB55CG Bluetooth SoC
• Arm Cortex-M4 main processor
• Arm Cortex-M0+ co-processor (for Bluetooth)
• 1 MB Flash memory (shared between main and co-processors)
• 256 kB of SRAM
• USB ROM Bootloader (no special hardware required)
• On-board chip antenna
• u.Fl connector for external antenna
• 128 Mb external SPI NOR Flash memory
• LiPo Battery charger
• 6 Analog Input pins
• UART, I2C, SPI, plus 7 Digital GPIO pins
• 32.768 kHz crystal for LSE/RTC
• User button and LED
• Standard SWD debug connector
