Mini SAM M4 is a minifigure-sized development board based on the Microchip SAMD51G 48-Pin 32-Bit ARM® Cortex®-M4F MCU running at 120Mhz with 18 I/O, two built-in LEDs, built-in Button, and an extra 2MB of memory.
The boards includes a micro USB interface for programming and power. Around the edge are 0.050″ spaced holes. The board has the following I/O pins available:
- 7 Analog In Capable Pins
- 2 Analog Out Capable Pins
- 18 Digital In/Out Capable Pins
The Mini SAM boards include two LED indicators; a standard builtin LED and an APA102 RGB LED. There are two built-in buttons as well; a RESET button and a user programmable BUTTON.
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 and libraries.
The boards include a 600mA 3.3V regulator, more than enough to power this little board and its built-in features. The board can be powered from a micro-USB or a battery connected to the BAT pin – it will automatically switch between the two.
The board comes pre-loaded with the latest available CircuitPython when produced. Please check for a new version here.
The board also comes with a UF2 bootloader, or if you need it be built from this source: UF2-SAMDX1
