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), 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
larger flash option (up to 8 MB) for bigger firmware and OTA
smaller footprint (13.2×16.6 mm)

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
faster CPU (240 MHz, Xtensa LX6)
Ethernet MAC for wired networking (add an external PHY)
more usable GPIO (28 vs 22)
