This reference design is for a multiparameter front end of a patient monitor that measures vital sign parameters like ECG, heart rate, SpO2 and respiration.it uses biosensing front end integrated circuits like the AFE4403 and ADS1292R devices, to measure these parameters. It also uses three TMP117 sensors to accurately measure skin temperature. This design can interface with the pace detection module to detect the pace pulse. The design also uses an isolated UART connection to transfer data to a computer. The entire front end subsytem runs on a rechargeable 3.7V li ion battery.
The meiji-led-ring is a compact light source that can be mounted on the front of a Meiji microscope. The illuminator uses 24 LEDs along with some high frequency boost drivers to avoid flickering when shooting. The device is powered by the USB-C port. A small ATSAML10 microcontroller is used to control the brightness of the LED driver. The user controls a series of touch sensors from the edge of the PCB.
Bluetooth ® Low Energy-NFC-v2.0 is an NFC expansion board for QN9020DK and an extensible QN9020 application development platform. This NFC expansion board is based on CLRC663+, a high-performance multi-protocol NFC front-end.
This reference design is a 2cm x 2cm RGB LED animation solution for battery powered applications using the LP5523 and MSP430FR2111 devices. The LP5523 device is an LED driver with a programmable control engine in a DSBGA package. The LP5523 provides realistic lighting patterns for applications that must fit on extremely small PCBs. The design demonstrates full functionality while using limited MCU resources.
Protues simulation example (8051)-parallel port to serial port
An ultra-mini frequency probe designed by foreign expert David Johnson. This frequency probe can help you debug the circuit by displaying frequency and voltage. It can measure periodic waveforms from 1Hz to 5MHz with an accuracy of 0.3%. Of course, it can also be used as a voltmeter. Use it to tell you the current voltage value.
Commercial electronic loads are more expensive, especially high-power loads such as computer power supplies that must handle transient current spikes well above their nominal ratings (1800W spike for a 600W GPU) and should be tested under worst-case conditions to Ensure stability.
This article briefly introduces the application example of brush drive technology based on MM32SPIN motor/power supply dedicated chip in "servo trajectory control".
TIDA-00714 TI Design is a complete TPS65982-based reference design for USB Type-C and power delivery applications. Allows users to develop various power profiles and alternate modes (such as DisplayPort) and debug existing USB Type-C and power delivery systems.
ThunderScope is the first oscilloscope designed specifically for Thunderbolt, allowing live sample data to be streamed to your computer at over 1 GB/s. This design eliminates all limitations of traditional oscilloscopes by leveraging the powerful processing capabilities of modern devices. Measurements are made fast and easy, with cramped UIs replaced by multi-window layouts and support for modern accessibility features. Sample memory was increased from megabytes to gigabytes, and the fixed list of protocols and trigger types was replaced by an ever-expanding repo. ThunderScope is also open source, so you have complete control over your data from the moment you sample it. You can easily add your own custom features and benefit from new features built by the community.
he STEVAL-MKI218V1 is an adapter board designed to facilitate the evaluation of MEMS devices in the AIS2IH product family.
