SIM卡普通卡座封装，大卡普通手机用的SIM大卡封装 来自摘抄(SIM card common deck package comes from the excerpt)

说明：  使用DCDC电源驱动步进电机正转和反转，PWM波控制转速(DCDC power supply is used to drive forward and reverse rotation of stepping motor, and PWM wave is used to control speed)

DAC7811驱动，好用的，测试电路是芯片手册12页给出的电路(The driver of DAC7811,I tested it and it could work well.)

抱闸控制器，用PWM方式控制电机抱闸，在有效开通抱闸情况下缓解抱闸发热(The brake controller, using PWM to control the motor brake, brake in effective opening off brake fever)

说明：  基于单片机的电阻、电容、电感测试仪 可测电容，电感，电阻等元器件的值(Resistance, Capacitance and Inductance Tester Based on Single Chip Microcomputer)

说明：  使用multisim软件设计的直流稳压保护电路，具有交流信号转直流信号，还进行了限压保护，最后通过光耦隔离器件作为开关，进行后续器件的驱动(The DC voltage stabilizing protection circuit designed by Multisim software has AC signal to DC signal and voltage limiting protection. Finally, the optical coupling isolation device is used as the switch to drive the follow-up device)

DWM1000室内定位源码，UWB超带宽室内定位。(DWM1000 indoor location source code, UWB ultra bandwidth indoor location.)

超声波模块制作了一个测距装置，HC-SR04自身不带温度补偿功能，所以加上一个使用DS18B20做的温度测量模块。整个系统包括：51单片机最小系统，超声波测距模块、温度测量模块、液晶显示模块。(The ultrasonic module has made a distance measuring device, HC-SR04 does not have temperature compensation function, so add a temperature measuring module using DS18B20. The whole system includes 51 single chip microcomputer minimum system, ultrasonic ranging module, temperature measurement module and LCD module.)
