| May 6 at 7:03 | comment | added | Gos | You can check in this post the explanation and how to set the mosfet: best-microcontroller-projects.com/tp4056-page2.html Also check the schematic of the module, it's what you are doing, more or less. | |

| May 5 at 19:14 | comment | added | Gos | Without the blue connection the battery will not power the MCU. And the diode is there to prevent that the battery is being charged and powering the load at the same time. When there are 5V in the USB rail, the diode is reverse biased. | |
