| Apr 28, 2020 at 3:51 | comment | added | Boots | Thanks Chris, so there is no benefit to try and reduce the current or voltage going to the camera? It ran fine on a 1A charger before I wired it up like the above... | |

Many of these cameras will overheat even with a suitable voltage power supply, especially the ones which are designed for aircraft and so assume all of a need to minimize weight (ie, no heatsink), airflow, and relatively short duration of operation given flight battery lifetimes. | |

Changed the power supply that wasn't working

And yes, that means the forward voltage drop of your LED is 2.0 V at 20 mA. $$3.7\ V - 2.0\ V = 1.7\ V$$ $$1.7\ V\div100\ Ω=17\ mA$$ It will probably be very bright depending on the LED...you can go higher on the resistor until it looks right to you. | |

| Apr 16, 2020 at 17:20 | comment | added | Aaron | depending on the LED 20mA may be overkill. Double check the datasheet. Most modern LEDs will run plenty bright on 5-10mA. | |
