Original question:

BOOSTXL-3PHGANINV: Power ground (PGND) and signal ground (GND) disconnection

BOOSTXL-3PHGANINV: why are there three grounding points between digital ground and power ground

Yao Wei
Prodigy 10 points
Part Number: BOOSTXL-3PHGANINV

Usually  digital ground and power ground require a connection point.

Why are there three grounding points in BOOSTXL-3PHGANINV?  What's the function of zero ohmic resistor? if  zero ohmic resistor is omitted, what will happen?

Thank you!
