Can I use the SmartPrintCoreH7x design in my own project?
Yes, under the terms of its GPL-3.0 license, which BoltzRnD chose for the repository.
Can I test firmware for the SmartPrintCoreH7x without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
