It operates with a DC Voltage ranging from 3V to 6V.SCL and SDA pins are used to interface with microcontrollers to receive 3-axis data from the magnetometer. This figure shows the pinout of the magnetometer module.Īs you can see from this pinout diagram that this module is easy to use and has fewer pins. But fortunately, module is available in market with all required components. Pin_15 is a data Ready interrupt pin which indicates when data is ready.Īs you can see that XC6206P332MR IC has a lot of pins and we need to use external components to make it work.Pin_13 VDDIO supplies power to the IO interface.Pin_12 SETC is a connection on the driver side of set/reset strap.Connect a 4.7 ♟ reservoir capacitor at this pin. Pin_10 is a pin for a reservoir capacitor.It removes the past magnetism stored in the sensor. Pin_8 is a set/reset strap positive input pin.It provides power for internal operations. It requires voltage in a range of 2.16V to 3.6V for the sensor to operate. Hence, microcontroller provides clock signal to IC. Magnetometer IC acts as a slave when we interface it with microcontroller. SCL is a master/slave clock input which receives clock signal from a master device. Pin1 and pin16 are communication pins for the I2C interface. Now let’s first discuss the pin configuration of this IC and after that we will see pinout of the module. HMC5883L magnetometer module consists of XC6206P332MR IC along with other components. Hence, we can use HMC5883L to determine the direction of objects HMC5883L IC Pinout Diagram They sense the magnetic field and based on this magnetic field it tells the direction of a device in which this magnetometer is integrated. Therefore, they need a sensor to identify directions. The unmanned machines like robots and drones cannot sense in which direction to move, unlike humans. HMC5883L module converts the magnetic field into differential voltage output on 3 axis pins. It is a multichip module that behaves as a digital compass IC to find the direction and measures the magnitude and direction of the magnetic field along the X, Y and Z-axis. HMC5883L is a magnetometer module developed by Honeywell using anisotropic magnetoresistive technology.
