Re: ESP32 PSRAM support

If any, post 2.1. Ok so how to look at esp32 rev1 SPIRAM support in IDF from a product planning standpoint? Will it always be second class citizen in terms of IDF updates, separate branch? Do you suggest to consider waiting for "ESP-NEXT" chip for fixed SPIRAM and first class IDF support?

Re: Interrupts issue

Example code uses

Code: Select all

OK if you want vdd_sdio for sleep and you exclude 3.3v psram then wroom is out.

They may be able to achieve tighter layout without the module. Not sure what their assembly costs are (so no clue if it's a win or loss in that respect). OTOH they possibly need to go through FCC/CE. That is possible, but I think most of their boards are two layer and will have routing, RF and impe...

He said this one https://world.taobao.com/item/542459608596.htm That LDO may have reasonably high threshold voltage and some USB ports could have low volt...
