Magnetometer
The 3-axis magnetometer chip IST8310 is integrated into the Board Type C. The communication
method of STM32 and IST8310 is IIC, which supports a maximum communication rate of 400 kHz.
The default IIC address of IST8310 is 0x0E. The schematic diagram is shown below.
PS connects GND: SPI mode
PS connects VDD: IIC mode
Load Imax: 116.3 mA
The operating current should be at least 500 mA
The chip should be far away from the power
cable and no device is allowed within 2 mm.
