Low power consumption champion
I am using this for a battery-powered sensor node. The deep sleep modes on the C3 chip are very efficient. Highly recommended for anyone moving away from the older ESP8266 models.

Great value, minor pin labeling issue
Excellent performance for the price. The Bluetooth LE range is impressive. Only giving 4 stars because the pinout silkscreen is a bit tiny to read without a magnifier, but the documentation online is clear.

Perfect for compact IoT projects
This SuperMini board is incredibly small yet powerful. The RISC-V architecture works flawlessly with the latest Arduino IDE and ESP-IDF. Wi-Fi connection is stable and setup was a breeze.

Best form factor in its class
The size-to-performance ratio is unmatched. I fit three of these into a project enclosure where only one larger board used to fit. Compilation times are fast and upload speed is excellent.

Beginner friendly
As someone new to embedded systems, this board was easy to get started with. Plenty of tutorials available specifically for the ESP32-C3. The USB-C port is a nice modern touch.

Solid performance, runs cool
Used this to control a small rover. It handles multiple servo signals and Wi-Fi telemetry without overheating. Would have liked a built-in battery connector, but that's a minor gripe.
Q: Can I power this directly with a 3.7V LiPo battery?
A: While the chip operates at 3.3V, this specific SuperMini board typically requires a stable 5V input via the USB-C port or the 5V/GND pins. If connecting a LiPo, please use a dedicated voltage regulator module to step down to 5V or 3.3V depending on the board's VIN specification.
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 specific limits defined in the datasheet to ensure stability. We recommend keeping individual pin loads under 20mA for safety.
Q: Is this board compatible with the Arduino IDE?
A: Yes, the ESP32-C3 SuperMini is fully compatible with the Arduino IDE. You need to install the ESP32 board package by Espressif Systems and select the 'Xiao ESP32C3' or generic 'ESP32C3 Dev Module' depending on your specific configuration.
Q: Does it have an external antenna connector?
A: No, this SuperMini version features an onboard PCB antenna to maintain its compact size. It provides sufficient range for most indoor and short-range outdoor applications. For long-range needs, consider our standard ESP32-C3 boards with U.FL connectors.
Q: Does it support MicroPython?
A: Absolutely. The ESP32-C3 chip supports MicroPython natively. You can flash the latest MicroPython firmware using esptool.py and start coding in Python immediately.
