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
- larger flash option (up to 8 MB) for bigger firmware and OTA
- smaller footprint (13.2×16.6 mm)
Choose ESP32-S2-WROOM if you need
- faster CPU (240 MHz, Xtensa LX7)
- 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-WROOM — 18×31 mm
