Re: ESP3212 IS OUT

Anyone going to miss the extra gpio pins? I guess it really depends on what your doing with the module.

Re: GPIO Matrix Document Available

Hi all, I created a xls spreadsheet from the esp I/O pin matrix PDF file. Please let me know if you find any errors. It may help someone when planning i/o for your project.

If Espressif posts official version I will be happy to remove this file.

Re: GPIO Matrix Document Available

Hi Thanks for clearing up the pin usage.

Is there a spreadsheet compatible version of the i/o mux table on page 4?

Re: GPIO Matrix Document Available

Are all pin uses mutually exclusive or may some be overlapped during use somehow?

Updated eagle Library

Hi all, I forked Sparkfuns esp32 Eagle library and updated it with the information found in the latest datasheets. I added an alternate symbol and an alternate device. Since a pin was deleted (io20) be-careful if you use this lib with your existing schematics. https://github.com/a2retrosystems/ESP32...

Related Documention

In the esp32 datasheet dated June2016 section 7.1 there are links to related documents. The first link (user guide) works but the other 2 do not. Is that because those links are incorrect or those documents are just not published yet?
