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-C6 vs ESP32-S2), so they differ in CPU, wireless and peripherals — not just packaging.

Choose ESP32-C6-MINI-1 if you need

Wi-Fi 6 — better battery life and throughput in busy networks
802.15.4 radio for Thread, Zigbee and Matter-over-Thread mesh
Bluetooth LE
smaller footprint (13.2×16.6 mm)

Choose ESP32-S2-WROVER if you need

faster CPU (240 MHz, Xtensa LX7)
PSRAM for camera frames, audio buffers and LVGL/large displays
larger flash option (up to 16 MB) for bigger firmware and OTA
native USB-OTG — act as a USB device/host without a USB-UART chip
more usable GPIO (37 vs 22)

Size, to scale

ESP32-C6-MINI-1 — 13.2×16.6 mm
ESP32-S2-WROVER — 18×31 mm
