APM32F030x8 Series MCU Handheld Laser Rangefinder

Geehy

A rangefinder is a tool designed according to the principles of optics, acoustics, and electromagnetic wave to measure length or distance. With the development of modern science and technology, traditional distance measuring tools can no longer meet people's needs. The handheld rangefinder breaks through the performance limitation of the traditional rangefinder. At present, it has been widely used in power, water conservancy, communication, construction, police affairs, agriculture, outdoor sports, and other industries.


Handheld laser rangefinder: It consists of the power supply, laser receiving and transmitting circuit, memory chip, display module, main processor, and control keys.



APM32F030x8 Series MCU Handheld Laser Rangefinder Solution


The industrial-grade general-purpose APM32F030x8 series MCU is based on Arm® Cortex®-M0+ core, with high integration, good reliability, and strong extended control function, can meet the Bluetooth communication, power adjustment, and diversified measurement requirements of handheld laser rangefinder, and realize simple, fast and accurate measurement operation.



Support Efficient Operation

· Efficient processing function: Based on Arm® Cortex®-M0+core, with the maximum operating frequency of 72MHz, and built-in up to 64Kbytes Flash and 8Kbytes SRAM, it can effectively improve the operation processing capability of the handheld laser rangefinder;

· A wide range of communication interfaces: UART supports Bluetooth module interface and Debug interface, and can realize program downloading, parameter setting, data interaction, and other functions, which is conductive efficient transmission of data information;

· Rich peripheral resources: The Built-in of up to 24Mbytes SPI and hardware DMA channels ensure the LCD does not get stuck and the content is refreshed in time.


Enhance Measurement Accuracy

· 12-bit high-accuracy ADC can amplify the received signal through a high-speed operational amplifier, determine the waveform phase through dynamic real-time sampling, and improve the accuracy of signal acquisition and processing.

· TIM can adjust modulation signals of different frequencies generated by PWM to realize the measurement of multiple measuring tapes.

· Build-in 4~32MHz high-accuracy crystal oscillator can obtain a more stable clock frequency and reduce the measurement error of the rangefinder.


Ensure Stable Operation

· With an operating temperature of -40℃~+105℃ and 4kV ESD, it has strong temperature adaptability and anti-interference capability and can ensure stable operation of the rangefinder even in the harsh outdoor operating environment.

· The voltage range is 2.0V ~3.6V. The built-in power-on reset, power-down reset, and configurable voltage monitoring modules ensure the output voltage remains constant under different working conditions.
