MAXREFDES89# is an mbed®-compatible shield for the rapid development of brushed DC motor applications. The shield contains four MAX14871 full-bridge DC motor drivers for driving up to 4 motors. A MAX17501 DC-DC converter allows the system to operate from a single 7 to 36VDC power supply. Four MAX4704 4:1 multiplexers permit setting the current regulation mode of the MAX14871, while two MAX5387 digital potentiometers provide the ability to set the motor current limit. A MAX7300 GPIO expander supports interfacing each motor driver circuit to the mbed enabled microcontroller platform.
6-Channel Li-Ion Battery Controller MC33772 Evaluation Board Targets Automotive and Industrial Applications with Isolated Daisy-Chain Communication
The average power consumption of this solution during standby is < 1 μA, and it can maintain standby state with low power consumption, and the data is still maintained when the power is turned off. This solution uses the LoRa transmission protocol to implement wireless update data function. Any host device can send data through the LoRa host module to update the electronic paper display content.

Simple branching of HDMI cable signals for analysis/verification of signal level and phase.
Intelligent real-time vehicle tracking system
Few elevator maintenance managers need to manage and maintain a large number of elevators, making it difficult to detect elevator faults in time. Based on ST's SensorTile, the author implements the sensor's automatic detection of elevator arrivals and faults, which can serve as input for possible intelligent control systems, thereby enabling more efficient and convenient elevator use and management.
In daily life, people often cannot stay away from the influence of radioactive radiation. For example, when they go to the hospital for a CT scan, professional practitioners in particular often need to effectively monitor the radiation dose rate in the environment. Nowadays, small personal dose values are commonly used. It is worn by individuals and the cumulative dose value within a period of time is calculated after regular submission. This project plans to design a model prototype of environmental dose monitoring equipment based on the GD32 domestic chip. It counts through Geiger tubes and uses digital tubes to display dose information in real time. When the dose rate reaches or exceeds the threshold, an audible and visual alarm will be generated. A GPRS module will be considered later. The data can then be uploaded to central management.
The goal of PSLab is to create an open source hardware device (with all resources fully open) that can be used by electronics enthusiasts to do experiments. And offers a range of sensors for engineering experiments, including oscilloscopes, waveform generators, frequency counters, programmable voltage, current sources and data loggers.
