SPI Voltage: 1.8 V on version of Flash 16MB and PSRAM 8MB, can it uses 3.3v modules? #12

Hi Guys,

Can I connect the 3.3v modules to YD-ESP32-S3's SPI pin which is 1.8v? I read the document from Espressif, found out the N16R8V , the SPI is only 1.8v instead of 3.3v.

可以将3.3V的模块连接到YD-ESP32-S3的SPI引脚吗，该引脚电压为1.8V？ 我阅读了Espressif的文档，发现N16R8V的SPI电压只有1.8V，而不是3.3V。 https://docs.espressif.com/projects/esp-idf/en/latest/esp32s3/hw-reference/esp32s3/user-guide-devkitc-1.html

Thanks

可能你有一些误解，文档中1.8v是内部flash电压和用户使用无关
