Power Supply for NodeMCU with Battery Charger & Booster
That is the reason why we are using a small boost converter Module made using some inductors, IC & resistor. Similarly to charge the battery and manage the battery we will use TP4056 Battery Charger Module. Apart from this we can power this circuit using 9V/12V Adapter as well. The LM7805 Voltage regulator IC limits the voltage up to 5V …
