Fair warning, not only am I trying to teach my son about electronics / robotics, I’m also trying to learn more myself…
I bought this product from my local radio shack. It’s designed as a robot with some circuitry to control the motors and sensors on a PCB, implemented as an Arduino shield. I thought it’d be cool to use a Raspberry Pi instead.
The shield itself is powered by 2x AA battery four packs combined together to provide 12v DC to the PCB. It is apparently designed to also power an Arduino since there’s no other power connection.
What I’m not sure about is whether this would be expected to power a Pi. I’m assuming a Pi is considerably more power hungry than an Arduino. I can tell you just with the shield properly connected per the instructions, the Raspberry Pi is not being powered through the Arduberry.
I guess my question is: is there a way to make this work? I noticed instructions for connecting external power (basically adding some components). Would this be necessary? Or would it be better for me to either connect it via the 5v pin -> RPi MicroUSB port, or to have a separate power source (would it be as easy as a four pack connected to a MicroUSB cable? I know that’s 6v vs. 5v but is that in tolerance?)
Thanks in advance for assistance. I have basic knowledge of electrical things (I can solder stuff together and use a multimeter), but it’s probably safest to assume I’m a beginner.
