A-Star 32U4 Robot Controller SV with Raspberry Pi Bridge
A few newbie questions, if I may…
The user’s guide warns to not connect multiple power sources… does this mean that I cannot connect to a computer with the USB if I have a battery connected to the 6-pin strip of terminal blocks at PWR+ (motor power) and am powering both the A-Star 32U4 and attached Raspberry Pi?
"Power provided to the Raspberry Pi can be switched off by driving the Raspberry Pi shutdown pin, RPISHDN, to 5 V."
So if while testing and rebooting and I do not want the attached Raspberry Pi to boot up I can just connect RPISHDN to onboard 5 V with a spare wire or shoudl I just remove the MicroSD so that it can’t boot?
