MAXREFDES67#: Universal input micro PLC

Maxim Integrated's MAXREFDES79# reference design is a fully compliant IO-Link version 1.1, 4-port IO-Link Master using a TEConcept software stack. The system contains four IO-Link master transceivers, a standard ARM® Cortex® M3 processor, and efficient industrial step-down DC-DC converters. The MAXREFDES79# comes preprogrammed and ready to connect with any compliant IO-Link device using a simple-to-use graphical user interface (GUI) program. Design files including schematic, PCB, BOM, GUI software, and compliance report are available for download.

DIY an SMT placement machine OpenPnP

Nowadays, almost all circuit boards use surface mount packaging, so I have always wanted to DIY a chip placement machine. After searching online for a long time, I finally decided to use the open source OpenPnP. The hardware and software are both open source.

Simple vibration analyzer

A MEMS acceleration sensor is used to convert the vibration signal into a voltage signal. The MCU collects the voltage signal into the MCU through the ADC module. Then the time domain signal is converted into a frequency domain signal through FFT changes, and the conversion result is displayed through the OLED module. This basically completes the function of the vibration analyzer.
