Which should you choose?
These run different SoCs (ESP32-C5 vs ESP32-C6), so they differ in CPU, wireless and peripherals, not just packaging.
Choose ESP32-C5-WROOM-1 if you need
- 5 GHz Wi-Fi: less congestion and higher throughput than 2.4 GHz-only
- higher clock (240 MHz)
- PSRAM for camera frames, audio buffers and LVGL/large displays
- larger flash option (up to 32 MB) for bigger firmware and OTA
Choose ESP32-C6-MINI-1 if you need
- smaller footprint (13.2×16.6 mm)
Size, to scale
- ESP32-C5-WROOM-1: 18×27.5 mm
- ESP32-C6-MINI-1: 13.2×16.6 mm
