I need to add more memory to my Lolin32 Webradio to avoid the constant dropouts that some stations have given. I use the ESP32-audioI2S library. Here in Brazil, access to components is extremely difficult, and we often resort to expensive imports via Aliexpress or eBay. The modules or memory chips that we have on the market are usually of the I2C flash type, like this one or this one. On Aliexpress, the only PSRAM I found was the 23LC1024 chip (128kB - $5.04). But I see chips 23K256 (32kB SPI serial SRAM - $1.38), 24C1024 (128kB I2C EEPROM - $2.30) and 25LC1024 (128kB SPI EEPROM - $1.84) available. Can I use these cheaper options?
