IMPORTANT: If you fabricated PCB verion v1.2 (see version label on the board) you need to drill out a misplaced via on diode D1 that shorts 5V rail to ground. The problem was fixed in v1.3.
IMPORTANT: If you fabricated PCB verion v1.2 (see version label on the board) you need to drill out a misplaced via on diode D1 that shorts 5V rail to ground (See [repair image](electronics/pcb_v1.2_fix.jpg) ). 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.
