The problem was fixed in v1.3. The electronics are designed in **KiCAD** and only commonly available modules (motor drivers and MCU boards) are used and connected by a simple PCB. No SMD soldering is required to populate the board to make the build extra accessible. For usual winding resistance of your motors, the device should be powered by $${\color{lightgreen} 5V-6V }$$ (2A) to keep current and heating to a reasonable level.
