 It is the QDPI ESP32 S3. This is the version that has four megabytes of flash and two megabytes of PS RAM. You can do so much on this. Use circuit Python, use Arduino. It's got the Wi-Fi built in. This has native USB. I've got my QDPI right there. I have the iSpy BFF there that allows me to plug in an SPI display. Look how quick this thing boots up. I'm going to go ahead and plug that in and boom, up and running ESP Wi-Fi analyzer. This thing will check the local SSIDs in its area based on the little tiny antenna it has on there and give you a display that tells you about the strength of the Wi-Fi signals that you're seeing. That right there, that is the ESP32 S3 QDPI with four megs of flash and two megs of PS RAM.
