Reclaimer Labs has launched an STM32WB Feather board based on a 32-bit dual-core Arm processor in the Adafruit Feather form factor, offering support for Bluetooth LE 5.0 and IEEE 802.15.4 wireless standards such as Zigbee and Thread.

We have already seen many dev boards featuring the popular STM32 family of wireless MCUs, like the Nucleo68 and MKR Sharky I. Like those, the STM32WB Feather is built around the STM32WB55CG SoC, which includes an Arm Cortex‐M4 clocked up to 64MHz that runs as the main application processing unit along with a Cortex‐M0+ at 32MHz as a co-processor for Bluetooth. It has an STM32WBCGU6 Bluetooth SoC at its core and has been designed for low power.

The SoC has 1MB of flash memory and 256kB of SRAM, as well as a USB ROM bootloader. Flash memory is shared between both the main and co-processors. The board is also equipped with an on-board chip antenna that radiates high-frequency electromagnetic waves. Additionally, the board packs a wide variety of I/O, including six analog input pins, UART, I2C, and SPI, plus seven digital GPIO pins.

You don't have to worry about device maintenance as STM32WB-based microcontrollers provide embedded security hardware functions such as 256-bit AES hardware encryption, PCROP read/write protection, JTAG fuse, and public-key cryptography with an elliptic curve encryption engine. The Firmware Upgrade Services (FUS), PCROP, and PKA feature ensure secured wireless stack updates, encryption key management, and code protection.

To get started, you need an STM32CubeProgrammer to program the development board. The rest of the detailed information can be found on the Reclaimer Labs' website. If you are interested in buying the STM32WB Feather, it is available via Tindie for just $45.
