I'm looking at your site. I'm extremely space limited with my XTMR setup.
What I'm in need of is a single RCVR with multiple XTMR's that can be identified when active. Only one transmitter will be active at a time.

Could I simply put a switch on an encoder data line and when activated, that encoder/XTMR combination will cause the same data line on the decoder to go high and turn on an LED?

Will the chip function with a 3.7v LiPo source? I'm likely limited to 100mAh capacity power source, for both encoder and XTMR.

Thanks,
Doug
