LORDWORLD BMM150 3-Axis Magnetometer Development Board

SKU CH-ER1A-10T4D

Three-axis BMM150 magnetometer board with I2C or SPI interface, 3.3 V/5 V logic compatibility and example code for Raspberry Pi, Pico, Arduino and ESP32

  • Measures magnetic fields in three axes with the onboard BMM150 sensor
  • Communicates via I2C by default, switchable to SPI through an onboard resistor
  • Works with 3.3 V and 5 V logic thanks to the built-in voltage translator
  • Includes online resources and manuals with examples for Raspberry Pi, Pico, Arduino and ESP32
  • New condition, ready for immediate development use

Compact magnetometer board

The LORDWORLD BMM150 adds three-axis magnetic sensing to a Raspberry Pi, Pico or ESP32 project. It communicates over I2C by default and can be switched to SPI by changing an onboard resistor. An integrated level translator makes the module safe for both 3.3 V and 5 V logic rails.

Developers needing heading data

Robotics, drone and navigation prototypes that require a digital compass will find the sensor ready to use with supplied example code. Projects that demand a calibrated 9-axis IMU or built-in sensor fusion should look at a different module.

I2C and SPI selectable interface

The single specification that decides fit is the dual-protocol interface selectable via an onboard resistor, letting the board match the host controller’s preferred bus without extra wiring.

Questions about this item

Will the BMM150 board's I2C address conflict with other sensors I already have on my Raspberry Pi bus?

The board uses the standard BMM150 I2C address; check your existing sensors' datasheets to confirm no address collision occurs on the shared bus.

How can I verify the magnetometer is returning valid heading data after wiring it to my ESP32?

Run the provided example sketch; the serial monitor should output changing X, Y, Z microtesla values that rotate smoothly when you turn the board.

Does the package include header pins or a connecting cable for the Raspberry Pi Pico?

The board ships as a bare PCB with plated through-holes; you must supply your own headers, jumper wires or soldered leads.
