Which should you choose?
These run different SoCs (ESP32-S3 vs ESP32), so they differ in CPU, wireless and peripherals — not just packaging.
Choose ESP32-S3-MINI-1 if you need
- vector / AI acceleration for on-device ML and DSP
- native USB-OTG — act as a USB device/host without a USB-UART chip
- more usable GPIO (39 vs 24)
- smaller footprint (15.4×20.5 mm)
Choose ESP32-WROVER-E if you need
- Bluetooth Classic (BR/EDR) for legacy SPP / A2DP audio
- more PSRAM (up to 8 MB)
- larger flash option (up to 16 MB) for bigger firmware and OTA
- Ethernet MAC for wired networking (add an external PHY)
Size, to scale
- ESP32-S3-MINI-1 — 15.4×20.5 mm
- ESP32-WROVER-E — 18×31.4 mm
