I am very new to electronics and trying to do something which I am not much aware of yet. I have a NodeMCU (based on esp8266) for which I need power supply of 5V and it required I guess more then 300mA for the properly working. I use to power it either by USB or mobile charger, which makes it working awesome so far.
But now I want to mount it to my own circuit so I can customise few things. So in order to create that power I have used a circuit diagram I found on YouTube.
The things is with this circuit diagram I can get the 5V power but the AMP is not what is needed, so my NodeMCU starts to heat up very quickly if I use this power supply and basically my NodeMCU looks damaged now.
So I just want to know few things :
- How can I increase the
mAin this circuit?
- Is it reliable for 24x7 running for days or even months?
- Is there any formula to calculate the capacitor (red capacitor from circuit diagram) I need to use to make it work?
I try to attach instead of
470uF 25v I replaced with
2.2uF 63v (it was available with me so thought to use this for testing purpose) it increased the voltage value. But the
mA or power stayed the same.
For basic reference, I have 230V AC power supply.
Any guidance will be helpful here!
Thank you! (in advance)
