SparkFun 9DoF Razor IMU M0

說明：SparkFun 9DoF Razor IMU M0將SAMD21微處理器與MPU-9250 9DoF（9自由度）傳感器相結合，創建了一種微型可重新編程的多用途IMU（慣性測量單元）。它可以通過編程來監控和記錄動作，通過串口傳輸歐拉角，甚至可以作為步數計步器。

9DoF Razor的MPU-9250具有三個三軸傳感器 - 加速度計，陀螺儀和磁力計 - 可以感應線性加速度，角速度和磁場矢量。板載微處理器Atmel的SAMD21是Arduino Zero和SAMD21 Mini Breakout板上的Arduino兼容的32位ARM Cortex-M0 +微控制器。

除了一對IC之外，9DoF Razor IMU還包括一個μSD卡插槽，LiPo電池充電器，電源控制開關以及用於項目擴展的大量I / O分支。它預編程有示例固件和Arduino兼容的引導加載程序，因此您可以通過USB連接自定義固件並刷新新代碼。

Description: The SparkFun 9DoF Razor IMU M0 combines a SAMD21 microprocessor with an MPU-9250 9DoF (9 Degrees of Freedom) sensor to create a tiny, reprogrammable, multipurpose IMU (Inertial Measurement Unit). It can be programmed to monitor and log motion, transmit Euler angles over a serial port or even act as a step-counting pedometer.

The 9DoF Razor’s MPU-9250 features three 3-axis sensors—an accelerometer, gyroscope and magnetometer—that give it the ability to sense linear acceleration, angular rotation velocity and magnetic field vectors. The onboard microprocessor, Atmel’s SAMD21, is an Arduino-compatible, 32-bit ARM Cortex-M0+ microcontroller also featured on the Arduino Zero and SAMD21 Mini Breakout boards.

In addition to a pair of ICs, the 9DoF Razor IMU includes a µSD card socket, LiPo battery charger, power-control switch, and a host of I/O breakouts for project expansion. It comes preprogrammed with example firmware and an Arduino-compatible bootloader, so you can customize the firmware and flash new code over a USB connection.
