Since I can't test it, I'm selling it as junk. It's supposedly unused. This is a small 9-axis inertial measurement unit (IMU), approximately 23 x 11 mm. It incorporates a 3-axis accelerometer, a 3-axis gyroscope, and a 3-axis magnetometer on a single chip (LSM9DS1). The interface is I2C, and a jumper for changing the address is located on the back of the board. By using only the necessary components and wiring, it's significantly smaller than previous products. Please note that some pins, such as those for interrupts and SPI communication, are not brought out. Specifications: Power Supply Voltage: 1.9 - 3.6 V Measurement Range: Accelerometer: ±2/±4/±6/±8/±16 g Gyroscope: ±245/±500/±2000 dps Magnetometer: ±4/±8/±12/±16 gauss Interface: I2C I2C address can be changed via jumper Size: 0.9 x 0.4 inches (approx. 23 x 11 mm) For more details ↓ https://www.switch-science.com/products/2881?srsltid=AfmBOopN1Nrb7ZjK6UUI7_p0pB1Ndi_44oZ0cz76m5JOhr48x_uRHaVQ
