Hi,

Tip: Remove your post from the Codebox!

You can easily find the same model used on the ESP32 modules. The W25QXX series is often used on modules and many other products based on the ESP32.

W25Q128, W25Q64 and W25Q32 are very common.

It would be good if there was a list of tested chips and preferred chips and unsupported chips ( viewtopic.php?f=2&t=20857 ) especially during shortages.

Hi WiFive,

Unfortunately we don't have such list. Maybe we can ask about this information due the current shortage.

Hi, I am developing a device with esp32-d0wd-v3 and I am interested in the same question. Please tell me if AT25QL128A-UUE-T is compatible? As I understand it, I need to configure VDD_SDIO to 1.8V for this using the MTDI pin.
