Blues Wireless Swan board adds castellated holes to Adafruit Feather form factor

We’ve often written about Adafruit Feather-compatible boards in the past, but Blues Wireless Swan board is a little different, as the STM32L4-based board comes with castellated holes instead of just through holes which allows the board to expose up to 55 GPIOs, or 36 more pins than a traditional feather-compatible board. The company also introduced the “Feather Starter Kit for Swan” that enables the board to work with the company’s Notecard LTE Cat-M/NB-IoT M.2 modem that ships with 10-year (up to 500MB) of IoT connectivity, as well as GPS/GNSS connectivity. The Swan board Swan specifications: MCU – STMicro STM32L4R5 Arm Cortex-M4 microcontroller clocked at 120Mhz with 2MB of flash and 640KB of RAM USB – 1x Micro USB port for power and programming Castellated holes giving access to 55 GPIO including: 8x analog input 16x digital 4x I2C, 3x SPI 1x USB OTG full speed 1x 14-channel DMA 12-bit ADC, […]
