It provides 2.4 GHz 802.11b/g/n Wi-Fi connectivity in a compact castellated module form factor.\n\nThe ESP32-S2 introduces native USB (both device and host), hardware-based security features, and Time-of-Flight (ToF) distance measurement support. It's well suited for IoT, wearable electronics, and smart home applications where Wi-Fi connectivity and USB interfacing are needed.\n\nKey Features\n\n\nESP32-S2 SoC – Single-core Xtensa LX7 @ 240 MHz\n\nNative USB – USB OTG support for device and host modes\n\n4 MB Flash + 2 MB PSRAM – WROVER configuration with external memory\n\n2.4 GHz Wi-Fi – 802.11b/g/n\n\nTime-of-Flight Support – Hardware-based distance measurement\n\nLow Power – Multiple power-saving modes\n\n\nSpecifications\n\n\nSoC – Espressif ESP32-S2\n\nProcessor – Single-core Xtensa LX7, 240 MHz\n\nFlash – 4 MB\n\nPSRAM – 2 MB\n\nWi-Fi – 802.11b/g/n, 2.4 GHz\n\nUSB – Native USB OTG\n\nBluetooth – Not supported on ESP32-S2\n\n\n\nWarning: This is the bare module only — intended for advanced users. You will need to solder it onto a custom PCB with supporting circuitry (voltage regulation, USB connector, buttons, etc.). Development is best done using the Espressif ESP-IDF toolchain. Arduino IDE and CircuitPython support are available but may be limited.\n\n\nResources\n\nCircuitPython Port (GitHub)\n\n\nPackage Contents\n\n1× ESP32-S2-WROVER Module\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":4116,"title":"Default Title","sku":"AF-4653","price":8.54,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
