Hello
I got interested in radio with microcontrollers a while back, and now I got some little ICs to work with. They are from integration.com namely:
the IA4220 (transmitter) and IA4320 (receiver), which both come in a 16pin TSSOP.
I'm working on the PCB and design at the moment, but before I continue I has some general, possibly basic questions.
Firstly, these things are tiny, therefore I'm guessing their current limit is obviously less than my favorite 16f628, at only 2mA for "digital output high level" and a maximum of 25mA input into any pin (from what I can make out)
I wanted to make the transmitter board separately to the main board with the PIC. Is there enough current to allow me to put a ribbon cable between boards, or does everything have to be on the one board???
Now I don't know too much, but is that enough to turn on and off my little bc337 or bc227 whichever one it was again?
Diving in the deep end here, but I hopefully will learn fast, thanks
