New here. About to buy a GrovePi for a senior design project. But to do what we need, the GrovePi must operate several grove relays, and maybe some sensors. (http://www.seeedstudio.com/wiki/Grove_-_Relay)
Now my questions:
How much power (or how many amps at 5V DC) can the GrovePi send to peripherals overall without frying the pi or the GrovePi’s components?
The GrovePi receives most of its power from the 2,4, and 6 pins on the pi I’m guessing?
Can I give the GrovePi external power, and send more current?
Are there any other limitations on what kinds of Grove Sensor’s I can use? I saw that only 3 analog sensors can be used, is that correct?
Trying to do my own research here, but I’m finding dumb-ed down information hard to come by… I want to learn! Just need help starting.
Thanks for any responses! -Aaron
