Mini SAM D51-017
Mini SAM D51 is a LEGO® minifigure-sized development board based on the Microchip SAMD51G 48-Pin 32-Bit ARM® Cortex®-M4F MCU running at 120Mhz. If you are familiar with some other of my minifigure-sized boards, you’ll notice I managed to create this one in a 2-layer format, which saves us money.
Please note that Rev 17 includes a PLCC-2 Reverse Gullwing LED on the back.
On-board Features
I/O
The board includes a usb-micro interface for programming and power. Rev 017 includes 0.050" spaced i/o along the edges that include castellated pins. I’m still experimenting with this layout, so it may or may not stay this way. I plan on having a “breakout” board to 0.100" breadboard-spaced pins. Maybe other add-on boards too.
Mini SAM D51 includes two LED indicators; a standard Arduino “Built-In” LED and an APA102 RGB LED - useful for CircuitPython - and available for programming in Arduino as well. There are two built-in buttons as well; a RESET button and a user programmable BUTTON.
Memory
In order to support CircuitPython, a 2MB Quad-SPI flash memory chip is included. This provides plenty of space for the CircuitPython program as well as space for user programming.
Other
The board includes a 500mA 3.3V regulator, more than enough to power this little board and its built-in features. The micro-USB circuitry includes optional provisioning for case grounding and ESD protection. Finally, The AREF input and recommended Analog and Digital power separation is present on the board.
BOM
CircuitPython
Bootloader available by building the UF2 for mini_sam_m4 from this repository: Uf2 Bootloader
Open Source
Please check my Github for the latest design files and bootloade/firmware. More details can be found on Github
