This board is a Swiss Army Knife for IoT security researchers, developers, and enthusiasts. The board can be used with different types of software, including third-party sniffers such as SmartRF Packet Sniffer, Sniffle, zigbee2mqtt, Z-Stack-firmware, Ubiqua Protocol Analyzer, our custom firmware, or you can even Specific software requires writing your own software.
This application note discusses ways to help system designers apply proper layout techniques and signal routing. The layout and component descriptions will minimize noise pick-up and manage the thermal dissipation in applications using PMUs.
Cruelfox, a forum expert, has updated his article to share with you an experimental idea of a CNC experimental power supply. The power supply uses two domestic chips, with a 3,000-word detailed explanation. He briefly talked about the first experimental power supply he made, whose shell was an aluminum medicine box and whose knob was a toothpaste cap. He mainly talked about the ideas and principles of the current mini PCB pocket version.
TIDA-00261-BOOST-DRV8711 is an 8-52V, 4.5A bipolar stepper driver stage based on the DRV8711 stepper motor pre-driver and CSD88537ND dual N-channel NexFET™ power MOSFETs. This module contains everything needed to drive many different types of bipolar stepper motors and can also be converted into a dual brushed DC motor driver. The BOOST-DRV8711 is ideal for those who want to learn more about stepper motor control technology and driver stage design. This kit is designed to be compatible with all TI LaunchPads based on the LaunchPad Pinout standard, while providing primary software/firmware support for the MSP-EXP430G2 LaunchPad with MSP430G2553.
The wind turbine is mainly 3D printed and equipped with a BLDC motor as a generator. Foldable and no larger than 2L soda bottle. Easy to replicate and low cost to manufacture.
SYZYGY is an FPGA extension standard for medium to high speed interfaces. This design is a breakout board for connecting dual Atto320 LWIR sensors. Designed to mate with existing sensor breakout boards that provide FFC connectivity.
An open source multimeter design based on STM32F1/F3, with dual-range V/I, RMS measurement, continuity, component testing and other functions. The author has made all design files open source, which is very suitable for DIY entry.
The Sensor Watch is unlike most smartwatches.
The 3D machine vision reference design uses Texas Instruments' DLP software development kit (SDK), allowing developers to easily build by integrating TI's digital micromirror device (DMD) technology with cameras, sensors, motors and other peripherals 3D point cloud. Highly differentiated 3D machine vision systems leverage the DLP® LightCrafter™ 4500 Evaluation Module (EVM) powered by the DLP® 0.45-inch WXGA chipset to provide the flexibility to control high-resolution, accurate graphics for industrial, medical and security applications.
RSL10 QFN EVB is used as the main control of IOT lamps. Because the GPIO of RSL10 is limited, the data protocol adopts single-line return-to-zero code communication method. The system only needs one GPIO1 as the LED RGBW driver. GPIO is used to drive WS2812. WS2812 is a control circuit and An intelligent externally controlled LED light source with integrated light-emitting circuit. Its appearance is the same as a 5050LED lamp bead, and each component is a pixel. The pixel contains an intelligent digital interface data latch signal shaping amplification drive circuit, a high-precision internal oscillator and a 12V high-voltage programmable constant current control section, which effectively ensures that the color of the pixel light is highly consistent. , the other ADC port is used to collect the temperature of the lamp, and when the temperature exceeds the limit standard, it automatically reduces the luminous efficiency of the lamp to avoid burning out the LED due to excessive temperature.
This dice mainly consists of an ESP8285-01F, six PCBs and 54 LEDs. Its structural design is very clever, and the exquisiteness of the structure is also reflected in the production process.

This reference design provides an output short-circuit protection solution for the TPS61088 boost converter. This function is implemented through the overcurrent protection (OCP) circuit. When the output is shorted to ground or the load current is higher than a certain value, the OCP circuit will disconnect the TPS61088 from the corresponding load. This solution only requires an additional low-cost comparator, a sensing resistor and a small N-MOSFET. By adding this small amount of circuitry, the TPS61088 is protected from output short circuit and overload conditions.
The MAXREFDES173# IO-Link® temperature sensor uses the MAX14827A IO-Link device transceiver and supports the IQ2 Development™ IO-Link stack.
