Texas Instruments (TI) introduced a simple, easy-to-use, 2-A synchronous buck converter TPS562207 in a SOT563 package. The device is optimized to operate with minimum external component counts and also optimized to achieve low standby current.

This switch mode power supply (SMPS) device employs D-CAP2 mode control providing a fast transient response and supporting both low equivalent series resistance (ESR) output capacitors such as specialty polymer and ultra-low ESR ceramic capacitors with no external compensation components.

The TPS562207 Simplified Application Schematic.

Features

2-A converter integrated 145-mΩ and 86-mΩ FETs
D-CAP2™ Mode Control with fast transient response
Input voltage range: 4.3 V to 17 V

SparkFun’s USB Type-C 5-20V 5A Power Delivery Board Features Qwiic Connector

Posted on 12 March, 202012 March, 2020 by Tope Oluyemi

USB Type-C introduced significant changes to the USB standard. The reversible connector eliminated the issue of trying to plug the connector in the right way every time. Another issue it addressed was allowing the flexibility to have USB power with an adjustable USB voltage from anywhere between 5V and 20V and up to 100W of power. The SparkFun Power Delivery Board takes advantage of the power delivery standard with the use of a standalone controller from STMicroelectronics, the STUSB4500.

SparkFun has now introduced a new method for powering your projects. This is possible through the flexibility of the USB Power Delivery Standard, which is a standalone USB Type-C power board with three configurable power delivery profiles.

Xtopher from SparkFun says

“Traditional power adapters can provide a wide range of current but the voltage stays fixed at 5V.” The company say “With the SparkFun Power Delivery Board’s USB-C connection it has the ability to achieve higher voltages, typically 5-20V and up to 100W of power. The Power Delivery Board uses a standalone controller to negotiate with the power adapters and have them switch to a higher voltage other than just 5V. This uses the same power adapter for different projects rather than relying on multiple power adapters to provide different output voltages.”

SparkFun Power Delivery Board is based on an STMicroelectronics STUSB4500 USB Power Delivery controller, which enables the negotiation of power delivery without an external microcontroller. However, SparkFun states that a microcontroller is still required for configuration, with the settings being stored in a non-volatile storage space on the controller itself. The controller board consists of input and output voltage ranges of 5-20V, with output current clocking up to 5A across three user-configurable power delivery profiles. It has a full USB Type-C Rev. 1.2 and USB Power Delivery Rev. 2.0 certification, and enables integrated VBUS voltage monitoring and PMOS switch gate drivers. Apart from its solderable pin headers, available also is a singular 3.3V Qwiic connector for solder-free connection into SparkFun‘s quick-connect I2C ecosystem. To configure the board, you will need the I2C bus. The Qwiic system makes it easy to connect the Power Delivery board to a microcontroller to set the NVM parameters to power your project via the Qwiic connector. Depending on your application, you can also connect to the I2C bus via the plated through holes for SDA and SCL.

The Power Delivery Board is available now for $24.95 before volume pricing on the SparkFun webshop. Available also is a hook-up guide available on the company’s learning platform. SparkFun has also written a library to control the Power Delivery board for the STUSB4500. You can obtain this library through the Arduino Library Manager. By searching for STUSB4500, you should see one written by SparkFun Electronics and you should be able to install the latest version. If you prefer downloading libraries manually, you can grab them from the GitHub Repository.

Raspberry Pi gets 3D TOF capture

Posted on 11 March, 2020 by mixos

Conrad Electronic is now selling Pieye’s Nimbus 3D time-of-flight (ToF) camera module for Raspberry Pi, expanding its range of accessories for development tools.

The ToF module offers a resolution of 352×288 pixels (100k) and operates in the measuring range of between 0.1 to 3m with a measuring accuracy of ±2%.

“Pieye Nimbus 3D brings the industry-proven time-of-flight technology to Raspberry Pi and is aimed at B2B customers in inventory management and warehousing who, for example, need to monitor fill levels,” explains Markus Pröller from Pieye. “Users in research and development, education, and robotics – such as for gesture control – can also benefit from the camera modules’ features, offered through a cooperation with Makerfactory. Typical users of the Nimbus 3D in the B2C market are makers, hobbyists and inventors as well as model-making enthusiasts.”

The time-of-flight technology integrated into Pieye’s Nimbus 3D determines the distance between the lens and the object via the propagation of modulated light pulses. The camera produces a distance value for each pixel and makes this so-called ‘point cloud’ directly available for evaluation.

Since time-of-flight technology enables 3D measurements with a single sensor, the especially compact design is of great advantage for use as top fixture with Raspberry Pi for object recognition, gesture control or robot navigation.

Handheld Aaronia Bug Finder RF Monitoring Device

Posted on 11 March, 2020 by mixos

Counter-espionage device can be used to check for the latest technology hidden listening devices, covert cameras, and unauthorized mobile phone usage in location such as sensitive locations, and in vehicles to locate hidden GPS tracking devices.

Saelig Company, Inc. announces the availability of the Aaronia Bug Finder RF Monitoring Device, which helps in the detection of hidden audio and video bugs and transmitters. Covering a frequency range of 10MHz – 12GHz, the Bug Finder can tackle the latest innovations in bugging technology that use modulation methods such as FM, NFM, WFM, AM, PCM, PAM, DECT, WLAN, GSM, SS, SSB. Both the 12-point LED display and the Auto-Sense button make settings easy to navigate.

Designed for the ever increasing threat from more sophisticated and higher frequency RF devices, the Bug Finder produces a dynamic acoustic ‘blip’. As the finder gets closer to the RF signal’s source, the frequency of the blip intensifies. When the blip hits a constant note/tone, the blip interval can be reset, enabling the user to refine tracking the source. Included in the kit for focused tracking are two LogPer antennas (900 – 2500MHz and 2000 – 11000MHz) as well as two omnidirectional antennas (20 – 1500MHz and 900 – 12000MHz).

Many other signal detectors depend on a 9V battery as their power supply, limiting the ability to minimize the package size. But the Bug Finder’s metal case houses a 3.7V Lithium polymer battery that not only enables the finder to be considerably smaller and lighter than other alternatives but also allows concealed handheld operation for over 3 hours with a charging time of 1.5 hours.

Features

Frequency range: 10 MHz – 12,000 MHz
Input impedance: 50 Ohm
Display: 12-point LED display
Sound: Internal speaker or headset (2.5 mm headset jack/ mono)
Power-supply: Lithium-Polymer battery (3.7 V)
Operational time: 3h, charging time: 1.5h
Connector: SMA microwave socket
Modulation methods: FM, NFM, WFM, AM, PCM, PAM, DECT, WLAN, GSM, SS, SSB
Settings: Via Auto-Sense button

The Aaronia Bug Finder RF Monitoring Device can be used to check for hidden listening devices, covert cameras, unauthorized mobile phone usage in location such as sensitive meeting rooms and offices, exam halls, hospitals, prisons, and in vehicles to locate hidden GPS tracking devices. Made in Germany by Aaronia AG, Europe’s award-winning, innovative manufacturer of RF site survey tools, handheld spectrum analyzers, antennas and EMC test probes, the Aaronia Bug Finder is available now from Saelig Company, Inc., technical distributor for Aaronia USA.
