Re: why the d2wd always reset auto for nothing?

Which power supply do you suggest for the d2wd? which consum you have measuring in the line from your supply to the SoC 3.3 power? FYI: my labor supply is on 3.3V and 5 Ampere the limit for the SoC is set by Resistor ( 4 Ohm ) in the line and i can get max 825mA then for testings. i do generally no...

Re: why the d2wd always reset auto for nothing?

Do you have any other good suggestion for this issue? 500ma is so crazy that unbeleavable. We met two chip are always reset reset and reset. If the d2wd chip is wrong or bug? perhabs you forget onetime bootstrap pulled up for intern regulator 1.8V then there is a rest risiko to damage the eMbeddedF...

@Smartisan D2WD works well: have a look here in this thread and this postings hope this helps further and please post the reset reset reset log - this helps us to find out what's going wrong and why. perhabs you can start simply the read ID prozess can you communicate with the eMbeddedFlash? example...

Re: Look out,I found so many problems with the d2wd!

Supply voltage range is 2.3-3.6V, same as for D0WD. I think you should test the chip esp32 d2wd , when you supply the voltage over 3.3v the chip will reset reset and reset. i think there is a big missunderstood here. first: the D2WD works very well in the supply 2.3 - 3.6V itself. BUT cause D2WD ha...

Re: Looking for a ready made board with revision 1 silicon

Hi all I'm wondering if there's any breadboard compatible rev.1 ("new silicon") dev boards out in the wild right now. If there is, I'd be happy to know a source. to answere your question in parts: as one and only board, and breadboard compatible i see only Nano32 - custom - with Rev1 ( 11...

Re: Strange capture of I2C on logic analyzer

like WiFive mentioned, use 3.3V as VCC cause ESP32 is 3.3V here is the datasheet of DS3231, side 2: the VCC is tolerant from 2.3V .. 5.5V, and typically 3.3V FYI: if you use an Arduino and DS3231 Breakout Board you can connect the DS3231 to the Arduino by 5V if the Arduino is a 5V, otherside if the ...

Re: ESP32 PSRAM support

Stable, no crash? Try for 80mhz? You have another wrover-kit to measure difference in power consumption? is the KIT/esp-idf up2date for 80 Mhz and psram combine? :) #yes will do a patch and test# but earliest after wednesday :) edit: forget to answere the top question: yes - i think it is stable - ...
