ESP32-C3FN4 Mini Development Board

This ESP32-C3FN4 mini development board is a low-power IoT edge device built around a RISC-V 32-bit single-core processor. It targets makers and engineers prototyping wireless projects that need integrated connectivity in a compact form factor. The board arrives with headers pre-soldered for immediate breadboard use.

RISC-V 32-bit single-core processor at 160MHz

The deciding specification is the RISC-V 32-bit single-core processor running at up to 160MHz. It provides 400KB SRAM and 384KB ROM alongside 4MB onboard Flash memory. Buyers who need more processing cores or larger memory capacity should consider other platforms.

Low-power operation with USB Type-C

The SoC supports flexible clock and independent power-supply controls to achieve low power consumption across different scenarios. An onboard ceramic antenna handles 2.4GHz Wi-Fi 802.11 b/g/n and Bluetooth 5 LE. A USB Type-C port provides the serial interface and power during development.
