The STM32 Nucleo-64 board provides an affordable and flexible way for users to try out new concepts and build prototypes by choosing from the various combinations of performance and power consumption features, provided by the STM32 microcontroller.
Use an idle Android phone to place it on a drone or unmanned vehicle/boat to realize wifi, 4G, 5G remote control of the drone, image transmission/data transmission/remote control integration. Supports APM and Pixhawk flight control (as long as it is compatible with Mavlink protocol), supports RTK differential GPS high-precision positioning (optional function, requires ublox NEO-M8P GPS module and Qianxun FindCM service account).
The 4K Ultra HD display reference design enables emerging applications of DLP Cinema® technology such as digital signage, laser TVs, and office or education projectors that require cost-effective high-resolution solutions for large, bright digital displays. Comes proven and reliable performance. Delivering twice as many pixels as competing products, DLP micromirror technology's advanced image processing and high-speed switching capabilities enable 8.3 million pixels of resolution on the screen, delivering clear and detailed images for any scene. Whether a stand-alone display system or embedded into an existing design, complete reference designs and development guides accelerate display product innovation.
The GD32F350 development board uses the latest ARM Cortex-M4 32-bit general-purpose microcontroller GD32F350RB launched by GigaDevice. This chip comes with a 2-way comparator and is very suitable for making a low-cost digital capacitance meter.
TIDA-00721 is a complete reference design that enables accurate temperature measurement using passive NFC tags in a flexible patch format. The system provides temperature readings via an NFC receiver (such as an NFC-enabled smartphone) tag. A high-precision temperature sensor (LMT70) is interfaced with an ADC (ADS1113), and the temperature data is sent to the reader using an NFC transponder (RF430CL330H).
STM32 Nucleo-64 development board using STM32G070RB MCU, supporting Arduino and ST morpho connections
This article designs to use GD32E231 to collect environmental data such as temperature, humidity, and infrared detection, and then transmit the data to the backend system through wireless transmission. This design uses GD32E231C8T6 to control the temperature and humidity sensor DHT11, human body infrared detection module, OLED and LoRa communication module, etc. The adopted temperature, humidity and infrared alarm signals are displayed through OLED, and the data is transmitted to the LoRa node in the background through the LoRa communication node, and finally uploaded to the host computer.
Design of dual-tone doorbell circuit based on 555 timer
This design is based on the design and development of the Modbus_RTU (RS485) bus Remote Inputs/Outputs Modules system of GD32E231.
Based on STM8S003K3 microcontroller, it has alarm and chime functions and automatic light sensing function.
The MicroByte is a tiny console capable of running games from the NES, GameBoy, GameBoy Color, Game Gear and Sega Master systems, with all components designed into this 78 x 17 x 40 mm package.
This design uses LM3S811 as the processor of the lubricating oil dielectric constant detection device, designs the AD5933 impedance measurement circuit, extracts capacitive reactance information from the impedance data, and calculates the change in the lubricating oil dielectric constant based on the change in capacitance to achieve lubrication control. Test the dielectric constant of oil and record the data to find out the change pattern between lubricating oil quality and dielectric constant.
The self-learning maze walking car can work in two modes.
NXPCWH-CTP-COP-YE is a removable debugger header for Power Architecture® processors.
This work, titled "Two Degrees of Freedom Pan-Tilt Robot Control Platform", implements a complete pan-tilt robot control platform. The system uses motion sensors as control handles to control the movement of the robot, and cooperates with the OLED screen to display the system's Current status. Using the control handle, you can control the movement of the vertical axis servo through forward and backward movements, and control the movement of the horizontal axis servo through rotation operations, thereby realizing two degrees of freedom control of the robot.
