ESP32-based devices come in all kinds of shapes and sizes, but one of the most powerful you can buy at the moment combines an ESP32-P4 and an ESP32-C6. The ESP32-P4 is the most powerful ESP32 you can get, but it’s aimed at Human Machine Interface devices especially, packing things like H.264 codec support, way more PSRAM, and more storage. It doesn’t support wireless technologies, though, though, and bolting on an ESP32-C6 gives it the ability to communicate over a Secure Digital Input Output (SDIO) bridge and leverage that hardware for Wi-Fi capabilities instead. And with that extra power, you can build and deploy the ESP Brookesia Phone project.
