The Blues Wireless Swan – a Feather Board based on the STM32L4R5 #Feather #CircuitPython @blueswireless

Blues Wireless introduces the most extensible Feather-compatible MCU on the market: the Swan !

Based on the powerful STM32L4R5 microcontroller from STMicroelectronics, the Swan operates at up to 120Mhz and provides developers access to 640KB of RAM, 2MB of flash, and 55 general purpose I/O ports including:

  • 8 Analog
  • 16 Digital
  • 1 SPI
  • 1 Quad SPI
  • 2 I2C
  • 4 UART
  • 1 USB

When operating in its low-power mode, the Swan board draws only about 8uA while retaining all of its memory, making it suitable for battery-powered devices. Swan also includes a CORTEX Debug connector enabling use of advanced development environments such as Visual Studio Code, IAR, and STM32CubeIDE.

Swan features support for C/C++, Arduino, and CircuitPython, and supports step-debugging in VSCode, IAR, and STM32CubeIDE with an optional STLINK-V3MINI .

Uniquely for Feather-compatible boards, the Swan satisfies developer needs from early prototyping through high-volume deployments. Developers can use Swan in conjunction with Adafruit’s myriad sensors and FeatherWing-compatible carriers. Or, due to its novel design consisting of a set of castellated edges around the board, the low-cost Swan can also be soldered directly to a parent PCB in order to utilize the full range of Swan’s I/O capabilities.
