=> the QSPI interface seems to use the pins 25, 27, 30, 31, 32 and 33. What is going on in the device ESP32D2WD? Based on the note below the table in the datasheet the flash interface uses other pins. In addition based on the timing the additional pins 25 and 27 are used for the CS and clock functionality of an optional PSRAM. => the QSPI interface for the flash consists of the pins 30, 31, 32, 33, 28 and 29. In the devices ESP32D0WD and ESP32D0WDQ6 the CS and the clock pins for the flash (external) are SD_CMD (pin 30) and SD_CLK (pin 31). In the newer documents, for example in the datasheet V1.3 in chapter "2.0 pin definitions" it can be found in the first note below the table (on page 9): "ESP32D2WD’s pins GPIO16, GPIO17, SD_CMD, SD_CLK, SD_DATA_0 and SD_DATA_1 are used for connecting the embedded flash, and are not recommended for other uses". Would it be possible to further clarify the planned/ realized usage of the pins GPIO16, GPIO17?- In my first post I added the link to the document "ESP-WROVER-KIT Getting Started Guide" where it is mentioned - in chapter 3- that GPIO16 and GPIO17 are used as the CS and clock signals for the PSRAM. 2 Sets of Pins are included with each push pin map Each box contains 50 Pins.

Or simply asked: Within which timeframe can we expect the release of the ESP32-WROVER module schematics that would answer all my above questions? Extra Push Pins for Maps 67 Reviews Regular price 5. The pin sale runs from Monday, May 17 to 11:59pm PT on Friday, May 28. 30.Īre I missing something or is my understanding correct?Īnother point: Does the internal 1.8V LDO supply enough power for the SPI flash and the PSRAM or do I have do use an external 1.8V supply? 25 of the ESP32 would be used as dedicated CS signal for the PSRAM beside the defined CS for the SPI flash on pin no. Is this information still valid?- In practice- as I understand it- this would mean that the two devices on the "SPI" bus (system SPI bus as I call it), the "system SPI flash" and the future PSRAM are sharing the "SPI" data lines however each of the two devices has its own clock signal (pin no. "ESP-WROVER-KIT Description" in the document "ESP-WROVER-KIT Getting Started Guide" Link, in chapter 3, it is mentioned that GPIO16 and GPIO17 are used as the CS and clock signal for PSRAM.
