Hi, I'm fairly new to electronics but hopefully this will be a fairly simple question!
I'm going to be building a circuit i've found here: http://homeeasyhacking.wikia.com/wiki/Nano_Breadboard_Interface
which uses RF modules to communicate with Home Automation stuff...
Anyway, my modules arrived today and i've found a datasheet for the reciever: http://www.telecontrolli.com/download/schede-tecniche-prodotti/receivers/14-rr3_it.html
Now, according to the circuit picture, the modules connects directly to the Nano +5v pin. I'm sure i've read that the Arduino pins provide 40mA, is that correct? And if so, the datasheet says this module needs 2.5mA (3mA Max).
There are no resistors in the circuit, so won't this blow up the RF module? Or am I missing something?
I've got an Arduino Uno, which I will be using instead of the Nano. I'm assuming all the voltages and currents will be the same, but is there anything I need to know in terms of differences between the two?
Many thanks in advance!
