I've just sent off a rev6 PCB for manufacturing with 2 final little tweaks, and then TinyPICO is done and I start the journey of "how am I going to manufacture them" ;)
Hi Seon

well done - i saw you have pSRAM working now on TinyPICO Rev6
relax :) you did it now.

best wishes

update:
"When ESP32-PICO chip connect a external psram,
the clock IO and data IO is fixed, but the CS IO can be
any unused GPIO, user can config it based on hardware design."

and now official support and more :)

Hi Everyone,

I just got back from Shenzhen on Sunday with my rev5 PCBs in hand, so I built one and TADA! PSRAM working like a champ!

I'm so glad I got past this little hurdle, and wanted to thank everyone here for your help and support on this Tiny journey ;)

rudi made an image from my LiveStream yesterday where I was showing it off... thanks rudi ;-)

Hello Seonroz, my name is jiy, I am from Shenzhen.

I encountered the same problem a week ago and I tried to add the SPI RAM chip to the ESP32-PICO-D4, but it never worked.

I connected the SPI RAM according to the schematic in Espressif's ESP32-PICO-D4 specification, but when I ran the program, I found that the memory test failed.

I turned off the memory check in the setup menu and it looks good, but it crashes when the program requests more memory than the ESP32-PICO-D4.

I think this is a memory chip issue. I bought more memory chips: IPS6404LSQ, LY68L6400SLIT, ESP-PSRAM64, I tested it with the DuPont series and the ESP32-PICO-KIT development board, but the results are still the same.

I was very frustrated, then I started looking for relevant information online and then saw this article.

I tried to connect to the SCLK pin of RAM using GPIO9, and GPIO9 will still warn the memory to detect the error.

Later I saw the video you connected to RAM. It took only 3 hours to solve the problem. Awesome!

Then I tried to shorten the DuPont wire and solder it directly to the SPI RAM pin. And I didn't use a 10K pull-up resistor. effective. I also wrote a program to detect the available memory size and found 4491944 bytes, which is so cool. Thank you for sharing and helping me solve this desperate problem! ! !

Later I tried to connect the SCLK pin to GPIO6 and GPIO10 and modified the program according to the hardware, but it didn't work. Then connect SCLK back to GPIO9 and run. I don't know why this is happening? Do you have the same problem?

Thank you for your unselfish sharing and wish you all the best! ! !

Hi Folks

cause ESP32-PICO-D4 is 3V3 we can use the Espressif's ESP-PSRAM64H for this.
It support 3V3.

btw:
ESP-PSRAM64H is used on the New Chip Thing "Chip7 2-2-A" ( ESP32-S2 )

best wishes
rudi ;-)

Datasheet ESP-PSRAM64 & ESP-PSRAM64H you find online at espressif

or here for download

Hi Rudi,
The picture of the module you've posted:
small Pico D4 Board with Proant 440 ( espressif's engineering example): ESP32_PicoD4_Board_with_Proant440.jpg -
is this a module that will be available soon on the market?
Thanks

was an ESP32-PICO-D4 engineering sample,
not sure, will this / is this given released on the market.

on the market is ESP32-PICO-D4-KIT from espressif. there are few other "maker" samples on market with OLED, PSRAM, or other things.
named TinyPico

or ESP32-PICO-D4-Development Board .. ESP32-CoinCell ...

and more few other.
