Re: Esp32 and software current limiting

Hello everyone, thank you for your very informative comments.

Circuit protection is provided by a general 20A-12V fuse. This fuse has been planned since the beginning of my project.

I will provide 4 fuses for the 4 outputs to have selectivity and abandoned my initial idea.

Esp32 and software current limiting

Hello guys, I'm working on a project with a esp32 pico v3. I would like to limit the current drawn by the MOSFETs by measuring the current consumed with an ACS71240KEXBLT-010B3. This component measures the current in +/-10A and sends a proportional voltage to the esp32. I would like to know if this ...

Both are dual Core and the PICO even seems to have more RAM. Thanks in advance. hello, Did you reach to convert...

I designed my own pcb with reference for pico module , heltec esp32 , using esp32 pico v3
But when i plug in , the device manager did not show anything
Also current does not show short circuit

Do I need to do anything after solder ?

Re: Encrypted OTA + Flash Encryption + Secure Boot

Hi Javqui, Thanks for the additional details. There have been some changes in the SPI flash during IDF V4.0 development, so this may be a regression. We will debug it and get back to you ASAP. (For a more stable but still prerelease experience you could try the release/v3.3 branch. See https://docs...
