### Motherboard
Motherboard is a separate PCB connected to the grip (with 4-wire cable), to the cascade (with 2-wire cable with XT60 connector) and to the shaper (with 4-wire cable). The main purpose of the motherboard is to orchestrate the functioning of O-ESD and to provide the user interface. <br>

The transformer has the following roles:<br>
The transformer has the following roles:
*to accumulate energy while the switching transistor is in the on state and release that energy to the high-voltage cascade when the switching transistor goes to the off state;
*to provide step-up voltage transformation from the low-voltage input to the high-voltage cascade and
*to provide galvanic insulation between the low-voltage input and the high-voltage cascade.
