Mini SAM M4

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.

Fig Pi

Fig Pi is a minifigure-sized development board based on the Raspberry Pi Foundation RP2040 Dual Cortex®-M0+ MCU running at 133Mhz with 16 I/O, one built-in LED around back, a 3×3 matrix of RGB LEDs, built-in Button, and an extra 2MB of memory.

Programming

The Mini SAM is capable of running on either the Arduino platform or the CircuitPython platform.

The Fig Pi is capable of running either Circuitpython or Micropython.

Both boards come with CircuitPython preloaded. In addition, they contain a UF2 bootloader that really eases the process of changing between programming languages.

Do It Yourself Assembly

Give it a try yourself, if you are feeling adventurous. Order some boards, collect the bill of materials, and try your hand at assembling the boards.
