Every figure here is checked against Espressif’s official datasheets. We’ve taken every care to keep it accurate — but datasheets are dense and mistakes happen, so if something looks off, please report it.
Which should you choose?
These run different SoCs (ESP32-S2 vs ESP32), so they differ in CPU, wireless and peripherals — not just packaging.
Choose ESP32-S2-WROVER if you need
- native USB-OTG — act as a USB device/host without a USB-UART chip
- more usable GPIO (37 vs 24)
Choose ESP32-WROVER-E if you need
- Bluetooth LE
- 2 CPU cores vs 1 — more headroom for RTOS / parallel work
- more PSRAM (up to 8 MB)
- Ethernet MAC for wired networking (add an external PHY)
Size, to scale
- ESP32-S2-WROVER — 18×31 mm
- ESP32-WROVER-E — 18×31.4 mm
