The cost of the board should be less than 50RMB, and it provides a lot of information, which is very suitable for novices to use as a development board to learn Linux.
Design secure POS with PCI and EMVCo, NFC, chip card and magnetic stripe readers using NXP technology.
Portenta X8 is a powerful industrial-grade SOM with a pre-installed Linux operating system onboard and can run device-independent software thanks to its modular container architecture. Securely perform OS/application OTA updates with onboard Wi-Fi/Bluetooth® Low Energy connectivity. It is basically two industrial products combined into one, with a power of no less than 9 cores. Utilize the Arduino environment to perform real-time tasks, while Linux handles high-performance processing. Portenta X8 features NXP® i.MX 8M Mini Cortex®-A53 quad-core up to 1.8GHz per core + 1x Cortex®-M4 up to 400MHz, and STMicroelectronics STM32H747 dual-core Cortex®-M7 up to 480Mhz +M4 32-bit Arm® MCU, up to 240MHz.
With the in-depth research of ultrasonic levitation technology by domestic and foreign scholars, ultrasonic levitation devices have developed from expensive horns and other equipment to structures composed of general-purpose commercial ultrasonic transducers. Combined with 3D model printing technology, any scientific researcher and Electronics enthusiasts can use these components to make ultrasonic levitation devices to facilitate related acoustic research. This technology was published in AIP Publishing by Asier Marzo et al. Based on its model, this design changes the main control MCU, uses the timer inside the MCU to generate accurate PWM waves, and improves the software so that the ultrasonic device can move the suspension stably during the axial suspension movement. Small objects in multiple nodes.
The author opens up the schematic diagram and supporting Raspberry Pi code. The simulation bandwidth is already 30MHz, and the frequency response is very close to the theoretical simulation, with a difference of about 0.02dB between 1kHz and 30MHz.
Uses infrared light sensing to determine changes in blood oxygen levels in the brain in real time. Use the device in less than ten minutes to learn how to directly change blood flow to your brain. Neurons do not store energy, so regional brain activity is closely related to changes in blood oxygenation, where healthy blood flow patterns are essential for high function and growth of the brain.
The quality of mobile phone screens is very high and the price is low. It is almost impossible to find mini displays made of mobile phone screens on the market, so this project is to solve this demand.
Somu is a small FIDO2 security key that you can use with your Google, Twitter, and GitHub accounts for two-factor authentication, or with your Microsoft account for passwordless login.
Flipper Zero is a portable multi-tool designed for developers and geeks with a toy-like body. It enjoys exploring digital content such as radio protocols, access control systems, hardware, and more. It's completely open source and customizable, so you can extend it in any way you like.
This is a new design for a universal gear indicator that can be installed on any motorcycle as an aftermarket accessory. Its main advantage is that its operation depends entirely on the movement of the gear lever, rather than being connected to speedometer and tachometer sensors (found in expensive commercial equipment), which are rarely found in older motorcycles. It consists of a main circuit including a 7-segment LED indicator, two Hall sensors attached to the motorcycle frame, and a small magnet placed on the gear lever.
The MCU-based solution for Face Recognition is a turnkey hardware and single source software solution for adding machine vision to products using the i.MX RT line of crossover processors.
SwarmDrive based on ESP32 has rich teaching documents, professionals and students can use it to easily learn various commutation algorithms and related knowledge of BLDC motors.
This is what smart home enthusiasts want to control their entire lights, thermostat, or any other smart device from their couch without having to activate a wall switch.
USB-Cereal is a powerful, fully open source development tool that simplifies testing, development, debugging and manufacturing of devices using USB-C. Using the extended capabilities of USB-C, this unique hardware saves time and effort by simplifying debugging and factory log capture, as well as firmware update procedures.
The basic concept of this work is slightly different from standard tools such as a reflow oven or soldering iron. Heat is provided from the bottom of the PCB.
Picoclick is a simple IoT button in a very small package. The size of the PCB is only 18x20mm, and the height with the 300909 battery is only about 10mm. It's able to connect to your local WiFi at an impressive speed of about 1.5 seconds on average. Yes, since it calls IOT-Button, it uses WiFi of course! This opens up countless possibilities for that little device.
The keyboard uses a modular design. The multi-functional scene interaction module on the left can be replaced with various custom components. By default, a Dynamic component with an e-ink screen and FOC force feedback knob is used; the keyboard body uses a shift register method to implement the key scanning circuit; The module and keyboard body can be used alone, or they can communicate and call each other through the serial port protocol.
