Thank you for help. I did try in my own to figure out and read about pull-up and I made a test on Proteus. I found the hard way that I need a resistor on the gate, but it did work. See the pictures. As mosfet I found BSS138, which on Proteus had a chip. I will make the board and test it live. Thanks...

Thank you for the suggestion.
Can you please make a hand drawing and post it.
What N mosfet you suggest.
What is the command to enable pull-up on GPIO16 ?
Please believe me, I am so new to that, and I need help.
Thank you very much.

My configuration and what i want to do. My ESP, it is powered by a battery or an external 5 volts. Both of them are connected to the VIN pin. The mosfet T1 decide if the power to board is from Lipo or from outside source. If no outside source, the power it is supplied by Lipo. If the board it is con...

Hello,
I would like to know if I destroy an ESP 32 if I apply 3.3 volts to GPIO16 for example, BUT is no power on VIN or on 3.3volts pin.
My VIN power it is controlled by another ON/OFF circuit, but on GPIO16 I have permanent power.
Thank you.

Thank you ESP_Minatel. Now i can look for a SIP which can accommodate this size of pins. As i said, i want to solder TWO SIP 19 pins, at 1" spacing, and use them as a socket for the module. So i can plug or remove the module from the pcb, without soldering to the board. Like the old sockets for dip ...

Hello, I posted by mistake the same question on the GENERAL DISCUSSION forum, but i believe here it is the best place to be. I bought and used in a project ESP32-DEVKITC-32U module from Digikey. It is a 38 pins module with 1 inch spacing between the two rows and antenna is pcb antenna, extended from...

I developed device with ESP32 DOIT. I want to change and move it to ESP32 HUZZAH32. The reason is that Adafruit product works from battery and has a battery charger on the module. I read the whole Adafruit data sheet but i am confused about the pins i can use without any conflict. On the DOIT i had,...
