STM32WBA65I-DK1 [STMicroelectronics]

The STM32WBA65I-DK1 Discovery kit is a complete demonstration and development platform for the STM32WBA65RIV7 microcontroller, featuring an Arm^® Cortex^®‑M33 core with Arm^® TrustZone^® and mainline security extension, 2 Mbytes of flash memory, and 512 Kbytes of SRAM, as well as smart peripheral resources.

The STM32WBA65I-DK1 Discovery kit embeds a powerful and ultralow-power radio compliant with the Bluetooth^® LE SIG resources. This Discovery kit enables a wide diversity of applications by exploiting low-power communication, the Bluetooth^® SIG isochronous channel feature related to audio capability for Bluetooth^® LE audio, Matter, and Zigbee^®.

The support for ARDUINO^® Uno V3 connectivity provides expansion capabilities with a wide choice of specialized add-on boards.

The STM32WBA65I-DK1 Discovery kit integrates an STLINK-V3EC embedded in-circuit debugger and programmer for the STM32 microcontroller with a USB Virtual COM port bridge. It comes with the STM32CubeWBA MCU Package, which provides an STM32 comprehensive software HAL library and various software examples.

The STM32WBA65I-DK1 Discovery kit leverages the STM32WBA series key assets to enable prototyping for a variety of wireless, low‑energy applications in fitness, metering, industry, or medicine, with state-of-the-art energy efficiency, and higher security.
