Ideal for education
Bought ten of these for our school robotics club. They are robust enough to handle student handling and connect reliably to our school WiFi. The plug-and-play nature saves us a lot of class time.

Perfect for micro:bit projects
This module made connecting my micro:bit to the internet incredibly easy. The MakeCode extension works flawlessly, and I was sending data to an MQTT broker within minutes. Highly recommended for students and makers.

Good starter module
As someone new to IoT, this was very approachable. The example codes provided on the wiki helped me understand how serial communication works. Took off one star because the antenna range is average indoors.

Great value, minor setup quirks
Works well with my Arduino Nano once I got the baud rate settings correct. The documentation could be slightly more detailed for advanced configurations, but for basic IoT tasks, it is excellent.

Reliable MQTT connectivity
Using this to bridge sensor data from an old Arduino project to Home Assistant. The connection is stable, and the power consumption is reasonable for battery-operated prototypes.

Compact and powerful
The form factor is perfect for small enclosures. I appreciate that it supports both 3.3V and 5V logic levels, which saves me from needing level shifters in my mixed-voltage setups.
Q: Can I use this with the micro:bit V2?
A: Absolutely, the Gravity WiFi module is fully compatible with both micro:bit V1 and V2 boards using the standard edge connector or crocodile clips.
Q: What is the maximum range of the WiFi signal?
A: In an open environment, the range is approximately 30-50 meters. Indoor range varies significantly based on walls and interference, typically covering a standard home or classroom.
Q: Is there a Python library available for this?
A: Yes, DFRobot provides a MicroPython library specifically for this module, which can be found in the 'Software' section of the product wiki page.
Q: Does this module support static IP configuration?
A: Yes, you can configure a static IP address through the AT command set or via the specific library functions provided in the Arduino IDE examples.
Q: Does it require an external power supply?
A: No, it can be powered directly from the 3.3V or 5V pin of your micro:bit or Arduino board during normal operation, though high-current WiFi transmission may benefit from a stable external source.
