| Sep 26 at 16:03 | comment | added | arjun kumar | @ sai,i am expecting a MOSFET circuit or low cost IC which can perform the switching of 5v (dc power supply) and 5v from Battery | |
| Sep 26 at 16:01 | comment | added | arjun kumar | @sai, the min(is 5v) and max(is 5.5v) voltages that the Nodemcu ESP-12E Vin pin can take without overheating AMS1117 (LDO) present on Nodemcu v1.0(overheating reduces its lifespan) and overheating will also spoils the WiFi chip functionality present on Nodemcu v1.0. the Vin- Vout voltage of AMS1117 (with 3.3v regulator output) at 800mA should be 1.3V | |
| Sep 26 at 15:58 | comment | added | sai | @arjunkumar, can your boost converter be programmed to provide 6V instead of 5V? | |
| Sep 26 at 15:56 | comment | added | arjun kumar | @Hearth, i will add the flyback diode, but the problem here is the Mechanical Relays slow switching speed | |

| Sep 26 at 15:30 | comment | added | Hearth | Your relay has no flyback network, which is potentially an issue but not the main issue here. | |
| Sep 26 at 15:20 | comment | added | sai | What are the min and max voltages that the Nodemcu ESP-12E Vin pin can take? I could not understand why you think the diode solution is problematic. Could you elaborate? | |
