Is it possible to power an EV3 hub via USB? I have a LEGO Mindstorm EV3 hub. I want to avoid buying rechargeable batteries by supplying power through battery box pins using an external variable power supply.
Is it possible to supply power to an EV3 hub via USB?
No, the only way provided to power the EV3 is through 6 AA-batteries or the expensive rechargeable battery box. Of course some DIY solution could work, anything that provides 9V DC or thereabouts works when the voltage is applied directly to the outer battery contacts...
