Easy to flash with Arduino IDE
Setup was incredibly smooth. Installed the board manager, selected the port, and uploaded my first sketch in minutes. Bluetooth LE performance is impressive.

Good board, minor documentation gaps
Hardware quality is excellent and pinout is standard. Had to dig a bit for specific register details, but the community support filled the gaps quickly.

Great learning tool
As someone new to embedded systems, this board is forgiving and easy to work with. The only downside is the USB cable included felt a bit flimsy.

Reliable for industrial sensors
We are using these for a sensor network project. They have been running continuously for weeks without crashing. Low power consumption is a huge plus.

Compact and powerful
The form factor fits perfectly into my custom enclosures. Signal strength is better than expected for such a small antenna. Highly recommended.

Perfect for IoT Prototyping
This board works flawlessly right out of the box. The RISC-V architecture is fast, and the Wi-Fi connection is stable. Great value for money compared to other dev boards.
Q: Does this board support MicroPython?
A: Yes, the ESP32-C3 Core Board fully supports MicroPython. You can flash the firmware using esptool.py or via the web installer.
Q: Is the CH343 driver automatically installed on Windows 10?
A: In most cases, Windows 10 and 11 will automatically install the driver. If not, you can download the latest CH343 driver from the manufacturer's website linked in our documentation.
Q: What is the maximum current output per GPIO pin?
A: Each GPIO pin can source or sink up to 40mA. However, the total current for all ports combined should not exceed the specified limits in the datasheet to avoid damage.
Q: Does this module have external antenna support?
A: This specific Core Board model uses an onboard PCB antenna. It does not have an IPEX connector for an external antenna. For long-range needs, please check our 'Pro' series models.
Q: Can I power this board via the VIN pin with 5V?
A: Yes, you can supply 5V to the VIN pin. The onboard regulator will step it down to 3.3V for the chip. Alternatively, you can power it directly via the 3.3V pin if you have a regulated source.
