Necessary to connect ALL V+ & GND pins?

Post by smhodge » Mon Jan 28, 2019 1:28 am

I am making a PCB to be a "motherboard" for the pyBoard. Can V+ and GND be connected via only one pin each instead of connecting to all the V+ and GND pins? I'm assuming they are electrically connected inside the pyBoard of course so my question is more one of currents, trace widths, ground loops, etc. It will make routing traces a lot easier on the motherboard if I don't have to use all those additional pins.

Using one pin for V+ & GND is ok. If V+ is used to power the PYBV11 you might consider a protective diode and some decoupling caps.

Thanks, I'll add those caps too.
