ENC03 datasheet
This angular velocity sensor utilizes a Coriolis force that act on a vibrating object when an angular
velocity is applied to it. Murata's unique ceramic bimorph vibrating unit is used as the sensor
element unit, thereby enabling piezoelectric ceramics to be used for both excitation and detection
The use of this unit simplifies equipment structure and circuit configuration, thus making it possible
to provide outstanding performance.
This sensor can be used for positional control and posture control of a moving object requiring
precision and quick-response measurements.

MMA8452 三轴加速度传感器
The MMA8450Q is a smart low-power, three-axis, capacitive micromachined
accelerometer featuring 12 bits of resolution. This accelerometer is packed with
embedded functions with flexible user programmable options, configurable to
two interrupt pins. Embedded interrupt functions allow for overall power savings
relieving the host processor from continuously polling data. The MMA8450Q’s
Embedded FIFO buffer can be configured to log up to 32 samples of X,Y and
Z-axis 12-bit (or 8-bit for faster download) data. The FIFO enables a more
efficient analysis of gestures and user programmable algorithms, ensuring no
loss of data on a shared I
2C bus, and enables system level power saving (up to
96% of the total power consumption savings) by allowing the applications
processor to sleep while data is logged. There is access to both low pass
filtered data as well as high pass filtered data, which minimizes the data
analysis required for jolt detection and faster transitions. The MMA8450Q has
user selectable full scales of ±2g/±4g/±8g. The device can be configured to
generate inertial wakeup interrupt signals from any combination of the
configurable embedded functions allowing the MMA8450Q to monitor events
and remain in a low power mode during periods of inactivity.

马达驱动电路MX612
该产品为电池供电的玩具、低压或者电池供电的运动控制应用提供了一种集成的有刷直流马达驱动解决
方案。电路内部集成了采用 N 沟和 P 沟功率 MOSFET 设计的 H 桥驱动电路,适合于驱动有刷直流马达或者
驱动步进马达的一个绕组。该电路具备较宽的工作电压范围(从 2V 到10V),最大持续输出电流达到1.2A,
最大峰值输出电流达到2.5A。
该驱动电路内置过热保护电路。通过驱动电路的负载电流远大于电路的最大持续电流时,受封装散热能
力限制,电路内部芯片的结温将会迅速升高,一旦超过设定值 (典型值150℃),内部电路将立即关断输出功
率管,切断负载电流,避免温度持续升高造成塑料封装冒烟、起火等安全隐患。内置的温度迟滞电路,确
保电路恢复到安全温度后,才允许重新对电路进行控制
