Somewhere while making the 9V USB rechargeable battery of my previous video (see [ Ссылка ]) , I managed to kill the boost converter. The module doesn't output the required voltage and the MT3608 chip on the damaged module gets very hot.
In this short video you can see how I repaired the module by replacing the chip (for less than 10 cents, see link below):
