The ESP32-C5 Mini is a compact development board featuring dual-band (2.4/5 GHz) WiFi 6, Bluetooth 5.x LE, and an 802.15.4 radio for Zigbee, Thread, and Matter. It includes two 9-pin headers, offering up to fourteen GPIOs, designed for IoT and Smart Home applications.
Similar to the XIAO ESP32-C5, it has a longer form factor and utilizes an ESP32-C5HF4 SoC rather than the ESP32-C5HR8 with 8MB SPI flash. This results in the absence of PSRAM and only 4MB of on-chip flash, with no external flash. The board features an additional four GPIO pins and incorporates both a built-in antenna and an IPEX antenna connector.
