Great value for bare PCB
Exactly what I needed for embedding into a custom enclosure. The pin headers were included which saved me time.

Precise readings for motor testing
Used this to measure magnetic flux in a DC motor project. The Modbus integration was straightforward and the display is easy to read in low light.

Responsive display
The OLED updates quickly when moving magnets near the sensor. Good refresh rate for real-time visualization.

Good module, documentation needs work
Hardware is solid and the display is bright. Had to guess some AT commands as the manual was slightly vague on syntax.

Perfect for industrial monitoring
We deployed several of these for non-critical magnetic field monitoring in our facility. They have been stable for months.
Q: Can I disable the display to save power?
A: Yes, the display can be turned off via specific AT commands to reduce current consumption.
Q: What baud rate does the Modbus interface use?
A: The default baud rate is 9600bps, but it can be configured via AT commands to match your system.
Q: Is calibration required out of the box?
A: The sensor is pre-calibrated at the factory. User calibration is available via software if needed for specific environments.
Q: Is this compatible with 5V Arduino boards?
A: Yes, the module operates between 3.3V and 5V DC. Ensure logic levels match when connecting to UART pins.
Q: Does the PCB come with mounting holes?
A: Yes, there are standard 3mm mounting holes on each corner for secure installation.
