Re: Training Course About ESP32 and ESP8266 with SDK-IDF 3.2

Looks very cool, but being in Portuguese, I don't see allot of people being able to making use of it.

Re: 3.0V 700mA LDO?

why don't you just connect it to a lab power supply set for 3.0v and try it.

Re: ESP32-DevKitC V4 flash memory available

They have the data sheet link right there on mousers site.
Per the data sheet:
"Both ESP32-WROOM-32D and ESP32-WROOM-32U integrate a 4 MB of external SPI flash"

Re: How to remove PWM signal from the pin?

you dont need to de-init the pin. just set the PWM to 0.

Re: Can the output current of the esp32 GPIO be reduced?

In my application, the ESP32 needs to drive an external contactor, which draws 29mA from the pin. It works, but I don't know if that can safely be done for 1-2 hours, or if I risk damaging the esp32 and better use a relay (there is only very little space, unfortunately). The typical method is to us...

Re: Help! ESP32 burnt by Motor Drive Module.

Thanks. I will try that. Could you tell me the physics theory of the small resistor? Do they protect the ESP32 from shortcut or something else? resistors limit current. the higher the value the more they limit. For example, if you set a GPIO pin high, but that pin is shorted to gnd for whatever rea...

Re: is there any issue using io0/io4 for i2c?

Not sure, Personally I steer clear of using GPIO0. Throw a scope on the SCL/SDA lines and have a look.
