I am planning to use an 8M2 or a 14M2 on a project to drive 8 UV LEDs. Considering using a 3.7V LIPO. What can I expect to happen when the voltage of the LIPO drops below 3V
No clash Phil, you made some additional valuable points.(This clashed with @inglewoodpete 's message - but, what the hell, I've typed it in now)
As already said, the main "concerns" should be with the LiPO and the LEDs, not the PICaxe. As far as I can see, UV LEDs require a forward voltage of more than 3v (as do white and blue LEDs); also, LiPO cells should not be discharged below about 3 volts (and might/should contain a "protection" chip to switch off any output drain below this voltage). But an 08M2 will keep "working" down to about 2.2 volts and the 14M2 to about 1.8 volts. Note that the PICaxe can use its CALIBADC instruction to measure the (battery) supply voltage without any additional components or pin connections.What can I expect to happen when the voltage of the LIPO drops below 3V
