The MicroBlocks virtual machine is designed for 32 bit microcontrollers with at least 16Kb of RAM and 64Kb of Flash memory. The source code for the virtual machine is built using Arduino board definitions and libraries and maintained as a project (to build all VMs) using PlatformIO.
The MicroBlocks firmware for supported boards can be installed from the IDE.
The MicroBlocks firmware for these boards must be installed using PlatformIO or Arduino IDE. They are not tested, documented, or supported by the MicroBlocks team.
