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.

在SparkFun 9DoF剃刀IMU M0結合了SAMD21微處理器與MPU-9250傳感器9DoF(自由度)創建一個微小的,可重複編程,多功能IMU(慣性測量單元)。它可被編程為監控和記錄運動,傳送歐拉角通過串行端口或甚至作為一個步驟計數計步器。
該9DoF Razor的MPU-9250擁有3個3軸傳感器,加速度計,陀螺儀和磁強計,這給它來檢測線性加速度,角速度旋轉速度和磁場矢量的能力。板載微處理器,Atmel的SAMD21,是一個Arduino兼容的32位ARM Cortex-M0 +微控制器還精選在Arduino的零和SAMD21迷你突圍板。
除了一對集成電路,所述9DoF剃刀IMU包括μSD卡插口,鋰聚合物電池充電器,電源控制開關,以及I / O突破的項目擴展的主機。它配備預編程示例固件和一個Arduino兼容的引導程序,讓您可以自定義固件並通過USB連接閃現新的代碼。
