ESP32 PICO D4 & External Ram

Postby thethinker » Mon Mar 12, 2018 1:16 am

I was just trying to decide whether I should use the PICO D4 in my design or the D0W. I read in the datasheet that the integrate SPI flash voltage is 3.3V and I was also aware that the ESP-PSRAM32 Uses 1.8V. Does this mean that I can never use External PSRAM with the PICO-D4?

Yes, at the moment you can only use ESP-PSRAM32 with D0WD. Not to say you can't get it working with D2WD or PICO — it's just that the only officially supported use case is with D0WD.

Hello,
So Based on the PSRAM documentations, there is a 1.8V and 3.3V version available. Is this out yet? Does this mean now we can use PICO-D4 with external ram?

No body?
I'm specifically talking about the ESP-PSRAM64H.
