Solid performance for home automation
Using these to control smart lights. They connect quickly to my network and haven't dropped connection once. Would give 5 stars if it had more analog pins.

Great value, minor documentation gaps
Hardware quality is excellent and matches the description perfectly. I had to look up some pinout details online as the included manual was brief, but overall a solid purchase.

Perfect for IoT projects
This board works flawlessly right out of the box. The USB-C connection makes programming easy, and the Wi-Fi range is impressive for such a small form factor.

Fast shipping and reliable
Arrived the same day as ordered. Successfully flashed MicroPython within minutes. The Bluetooth LE functionality is stable for my sensor network application.
Q: What is the maximum operating temperature?
A: The commercial grade ESP32-C3 chip typically operates reliably between -20°C and 70°C. For industrial ranges, please check the specific datasheet revision.
Q: Can I use this with the Arduino IDE?
A: Absolutely. You just need to add the ESP32 board manager URL to your preferences and install the ESP32 package by Espressif Systems.
Q: Does this board support external antennas?
A: No, this specific model comes with an onboard PCB antenna only. It does not have an IPEX connector for external antennas.
Q: Is the 5V pin capable of powering other modules?
A: Yes, the 5V pin can output power from the USB source to power small peripheral modules, but please ensure the total current draw does not exceed the USB port limits.
Q: Does it come with headers pre-soldered?
A: No, the board is shipped without headers soldered to allow for flexible mounting options. You will need to solder them yourself if required.
