Does the ESP32 support PSRAM DTR?
It's my first time designing a board using ESP32-PICO-D4. I'm trying to choose an SPI memory chip, but I can't decide between Winbond: W25Q128JVPIQ (NOR Flash spiFlash, 3V, 128M-bit, 4Kb Uniform Sector) Winbond: W25Q128JVPIM (NOR Flash spiFlash, 3V, 128M-bit, 4Kb Uniform Sector, DTR) They're identic...

Re: What exactly is CAPP, CAPN, VP, and VN?
These are for an on-board LNA for the ADC; unfortunately, there were issues with the LNA and the feature got dropped from the datasheet. You can still use the pins as digital inputs (or ADC pins if you don't use WiFi) Oh, I see. That's interesting. It's good to know the story behind it. Thank you! ...

Is GPIO different in ESP32-PICO-D4?
I am reading the datasheets of ESP32-PICO-D4 and ESP-32. However, I noticed that the GPIO functions were lacking in ESP32-PICO-D4 within the datasheet pin configuration. My question is: Can I still use pins 10, 11, 12, 13, 17, 20, 21, 22, 24 as GPIO pins on the ESP32-PICO-D4? Datasheet links ESP32 (...

What exactly is CAPP, CAPN, VP, and VN?
I received footprints for the ESP32-PICO-D4 that had these grouped together: https://snipboard.io/eUcnW6.jpg The ESP32 datasheet and the ESP32-PICO-D4 datasheet do not mention anything detailed about them. https://www.espressif.com/sites/default/files/documentation/esp32_datasheet_en.pdf https://www...
