# tests
|
|
|
|
all traces will be 10mm wide
|
|
- each track should handle around 6.5A of current @ 10c internal and 12.7A external
|
|
all pcbs will be 1oz copper
|
|
all pcbs will be 4 layer FR4
|
|
all other areas of the PCB will have a ground plane
|
|
all traces will be 100mm after the start of the connector
|
