Re: ESP32 Pin Layout (for QFN 5*5), Pin25, Pin26

Hi Rudi, Yes, it's 16Mb = 2MB. Yes, available in small quantities from sales. Yes I have 300 in front of me. Just preparing to re-spin board due to this issue. I don't think the pinout diagram showing the numbers is correct. I can't get a good picture with my phone, unfortunately. Nor can I really ...

Re: ESP32 Pin Layout (for QFN 5*5), Pin25, Pin26

Yes, plus it has built-in 2MB? flash in D2 configuration, so it's more secure and much smaller overall. D2 would be 16 Mbit ... Embedded Flash 0=No Embedded Flash 2=16 Mbit .. ordering_info.png .. I can confirm from inspecting .... thank you iosixllc i read between the lines - ESP32 with embedded F...

SPI PSRAM is not as standardised as SPI flash, there can be differences between vendor implementations, command sets, etc. Angus, do you can tell more about the manufacturer of the used pSRAM in WROVER and where we can buy? is there a datasheet available from this used pSRAM? thank you best wishes ...

It was previously UINT8 len = sizeof(p_data->set_addr); . Thanks! thanks you mean this line in code`? /*************************...

Re: Low Rate WIFI Protocol LR
