Howdy,
I appologize for the extreme newbee question I'm about to pose.
I am planning a controller circuit based around a PIC18, that will include an LCD display which operates at 5V.
However, I want to make use of one of Microchip's RF transceiver modules which operates at 3V.
The term "voltage divider" comes to mind.
Before I start down a frustrating path, is it uncommon or ill-advised to attempt to mix components that require differing operating voltages into the same device?
Digital communication between the PIC at 5V and the RF module at 3V will be required. It's not clear to me how that will work...
I presume that this sort of topic has been discussed before, but I don't know what key phrases to search for.
Thanks in advance,
Eric
