Two small green circuit boards with USB-C ports and pin headers

LORDWORLD

LORDWORLD ESP32-C3FN4 Mini Development Board 2-Pack with Pre-Soldered Headers

SKU CH-7M1Q-DM1ZA

Two RISC-V boards with pre-soldered headers, 2.4 GHz Wi-Fi, Bluetooth 5, 15 GPIO and 400 KB SRAM for compact IoT prototypes

  • RISC-V single-core processor reaches 160 MHz for responsive IoT control
  • 4 GHz Wi-Fi 802.11 b/g/n and Bluetooth 5 LE enable wireless projects
  • 400 KB SRAM plus 384 KB ROM and 4 MB Flash store code and data
  • 15 GPIO pins with 3 SPI, 1 I2C, 2 UART, 1 I2S, 2 ADC connect diverse peripherals
  • USB Type-C port with integrated serial controller simplifies programming and power

ESP32-C3FN4 development board pair

This pack supplies two LORDWORLD ESP32-C3FN4 mini development boards with headers already soldered. Each board uses a 32-bit RISC-V single-core processor running up to 160MHz and includes 400KB SRAM, 384KB ROM and 4MB onboard Flash. The pair suits makers building Wi-Fi and Bluetooth LE connected devices.

Sustained-load behaviour

Under continuous operation the 160MHz core handles sensor polling, protocol stacks and logic without thermal throttling. 2.4GHz 802.11 b/g/n Wi-Fi and Bluetooth 5 LE maintain links while the 15 GPIO pins drive peripherals through 3 SPI, 1 I2C, 2 UART, 1 I2S and 2 ADC channels. The castellated module can be soldered directly to a carrier board for permanent deployment.

Thermals, noise and power

The low-power SoC draws minimal current and runs silently with no moving parts. Flexible clock control and independent module supply settings let the firmware reduce consumption in idle or deep-sleep phases. An onboard ceramic antenna keeps the RF path compact, and the USB Type-C port provides both power and serial debugging during development.

Perguntas sobre este artigo

How much heat or power does the RISC-V processor draw when running at 160 MHz all day?

The ESP32-C3FN4 is a low-power SoC designed for flexible clock and independent module power settings, enabling low consumption across different scenarios.

What power source and host computer do I need to program the board through its USB Type-C port?

A USB-C cable and a computer with a USB port are required to supply power and provide the serial connection for flashing firmware.

Will the Bluetooth 5 LE radio interfere with older 2.4 GHz Wi-Fi 802.11 b/g/n gear I already use?

Both radios share the 2.4 GHz band; the chipset handles coexistence, but heavy simultaneous traffic on both may reduce throughput on either link.
