Dear WiFive, I am going to use ESP32-PICO-D4 in my project becuase of space saving as it includes "ESP32 chip, crystal oscillator, flash memory, filter capacitors, and RF matching links" . I will be using external flash to increase memory size as embedded flash is of 4MB. WiFive wrote: I guess you c...

Dear Group Members, The data sheet of ESP332-PICO-D4 says that "Pins IO16, IO17, CMD, CLK, SD0 and SD1 are used for connecting the embedded flash, and are not recommended for other uses" . If I want to use an external flash with ESP32-PICO-D4 can I use the same pins as of integrated flash of ESP32-P...

Dear WiFive,

Thank you for the reply. I have gone through the document and it is written that we can "Any GPIO Pins" for General Purpose SPI. But for EMAC If i want to use EMAC RMII than I cannot use JTAG pins functionality because MTCK is overlapping with EMAC_RX_ER ?

Hello Group Members, ESP32-PICO-D4 module integrates 4-MB SPI flash. I am a little bit confused in the communication between the integraed SPI Flash and ESP32. The integrated flash is of 3.3V so VDD_SDIO(3.3V). The following are the connections of SPI flash in ESP32-PICO-D4: Pin Number1: /CS = GPIO1...

Hello Group Members,

I want to connect external sRAM and flash with ESP32-PICO-D4 in my project. Can any one recommend how can I connect sRAM and flash with ESP32-PICO-D4 while I also need the functionality of Ethernet RMII in my project.

I shall be thankful for valuable suggestions.

Hello.. I am going to use ESP32-PICO-D4 in my project with external flash and sRAM. I want to use VSPI in my project for communicating with external flash and sRAM. The SPI pins are already used in ESP32-PICO-D4 for connecting embedded flash and these pins cannot be used. So my question is if i am u...
