Which should you choose?

These run different SoCs (ESP32-C5 vs ESP32), so they differ in CPU, wireless and peripherals, not just packaging.

Choose ESP32-C5-WROOM-1 if you need

Wi-Fi 6: better battery life and throughput in busy networks
5 GHz Wi-Fi: less congestion and higher throughput than 2.4 GHz-only
802.15.4 radio for Thread, Zigbee and Matter-over-Thread mesh
PSRAM for camera frames, audio buffers and LVGL/large displays
larger flash option (up to 32 MB) for bigger firmware and OTA

Choose ESP32-MINI-1 if you need

Bluetooth Classic (BR/EDR) for legacy SPP / A2DP audio
2 CPU cores vs 1: more headroom for RTOS / parallel work
Ethernet MAC for wired networking (add an external PHY)
more usable GPIO (28 vs 22)
smaller footprint (13.2×19 mm)

Size, to scale

ESP32-C5-WROOM-1: 18×27.5 mm
ESP32-MINI-1: 13.2×19 mm
