Would a single Li-ion work well with a Groove V2 driving an LPC-815 (LOC) at only 140mA?
I know the Vf of those LOC/SOC diodes are only something like 2.4v @ lower currents.
So there should still be some overhead with the driver needing +1.2v...
I want to build a low power (~50mW red) pen style pointer using a single Li-ion cell.
Do you think I'd get decent runtimes from a 900mAh battery in such a configuration?
Would it be worth it to use a 635nm diode to get more brightness and less power?
