Product details

Small-form-factor Wi-Fi 4 + Bluetooth 5.0 module with 4 MB flash

The ESP32-C3-MINI-1-N4 is a compact 53-SMD module from the ESP32-C3 series, integrating a RISC-V single-core MCU with 4 MB flash, 384 kB ROM, and 400 kB SRAM. It supports 802.11b/g/n Wi-Fi at 150 Mbps and Bluetooth v5.0, covering the 2.412 GHz to 2.484 GHz ISM band. Transmit power reaches 20.5 dBm, which provides a stronger RF link than the 18 dBm typical for many IoT modules — useful for penetrating walls or extending range in smart-building sensors. Receive sensitivity is -104 dBm, giving a solid noise floor margin for weak-signal environments. The module uses a PCB trace antenna, so no external antenna component is needed on the board — saves BOM cost and layout space, but the antenna pattern is fixed and cannot be tuned for a custom enclosure.

The supply range is 3.0 V to 3.6 V, a single 3.3 V rail with ±0.3 V tolerance — a common LDO output, but the regulator must handle 290 mA to 350 mA during transmit bursts. Receive current is 82 mA to 84 mA, so the average draw is well under 100 mA in a typical duty-cycled sensor. The 53-SMD module footprint is surface-mount, reflow-compatible with standard lead-free profiles.

Frequently asked questions

What is the difference between ESP32-C3-MINI-1-N4 and ESP32-C3-WROOM-1?

The ESP32-C3-MINI-1-N4 uses a PCB trace antenna and comes in a 53-SMD module package, whereas the ESP32-C3-WROOM-1 typically uses an external antenna connector and a larger PCB footprint. The MINI variant saves board space and BOM cost by integrating the antenna, but the WROOM version allows antenna tuning for specific enclosures. Both share the same ESP32-C3FN4 IC and memory configuration.

Is ESP32-C3-MINI-1-N4 compatible with Arduino IDE?

Yes. The ESP32-C3 series is supported by the Espressif Arduino core, which can be installed via the Arduino IDE Boards Manager. The module exposes serial interfaces including UART, SPI, I²C, I²S, and JTAG, covering the typical debug and peripheral connections needed for Arduino sketches.
