Description

The WeAct Studio ESP32-C3FH4 Core Board delivers a modern, RISC-V-based platform for embedded IoT development. Its Espressif ESP32-C3 SoC combines a 160MHz single-core processor with 400KB of SRAM, enabling low-power wireless applications. The board integrates a USB Type-C to serial/JTAG bridge for seamless firmware flashing and debugging without external programmers.

With native support for IEEE 802.11b/g/n Wi-Fi and Bluetooth 5.0 LE, it’s suited for smart home devices, sensor nodes, and wireless gateways. The 4MB SPI flash provides ample storage for OTA updates and data logging. Its compact form factor and comprehensive GPIO breakout make it ideal for prototyping and integration into final designs.

Key Features

  • RISC-V architecture (ESP32-C3) offers power efficiency and modern instruction set for embedded C and MicroPython development.
  • Single-core processor clockable up to 160MHz balances performance with low active current consumption.
  • Integrated 2.4GHz RF front-end supports Wi-Fi 802.11b/g/n and Bluetooth LE 5.0 with external antenna option.
  • USB Type-C connector provides robust power delivery, data transfer, and CDC-based serial console access.
  • Pre-configured boot and reset circuitry enables one-click firmware uploads from Arduino IDE or esptool.py.
  • All available GPIO pins are broken out, including those for SPI, I2C, UART, ADC, and PWM peripherals.
  • On-board blue user LED and accessible button simplify basic input/output testing during development.
  • Low deep-sleep current enables battery-powered IoT node deployments with multi-month operational life.

Applications

  • Smart home automation controllers and wireless sensor hubs.
  • Prototyping for battery-operated Bluetooth LE beacons and tags.
  • Wi-Fi-connected data loggers for environmental monitoring (temperature, humidity).
  • Educational platform for learning RISC-V architecture and wireless IoT protocols.
  • Gateway edge device for translating BLE sensor data to Wi-Fi/MQTT networks.

Frequently Asked Questions

How do I program the WeAct Studio ESP32-C3FH4 board using the Arduino IDE?

First, install the ESP32 board support via Arduino's Board Manager using the URL https://Espressif.github.io/Arduino-esp32/package_esp32_index.json. Select 'ESP32C3 Dev Module' as your target. Connect the board via USB-C, choose the correct COM port, and upload your sketch. The board uses the integrated USB-serial bridge, so no external programmer is needed. Ensure you have the latest ESP32 Arduino core for full GPIO and wireless feature support.

What is the procedure for entering bootloader mode on this board?

Hold down the 'BOOT' button (if labeled) or the designated GPIO pin, then press and release the 'RST' button while keeping BOOT held. Release BOOT after the board enumerates as a serial device. Alternatively, most development environments like esptool.py or PlatformIO can automatically trigger reset via DTR/RTS signals over USB, making manual button presses unnecessary for routine uploads.

Can I use an external antenna with the ESP32-C3FH4 for improved Wi-Fi range?

Yes, the ESP32-C3 chip supports an external antenna via an IPEX connector. You must carefully desolder the 0-ohm resistor linking the RF path to the onboard PCB antenna and solder a jumper to connect it to the IPEX port. Always ensure impedance matching (50 ohms) and use a 2.4GHz-rated antenna. This modification will disable the internal antenna, so range testing in your enclosure is recommended post-installation.
