PicoScope 2-Channel 5 and 16GHz Sampler-Extended Real-Time Oscilloscopes

The PicoScope 9402-5 and -16 bring very high-speed performance at less than half the cost of other traditional benchtop solutions with two high-resolution 12-bit channels driven by up to 2.5TSa/s (0.4ps) equivalent-time sampling

Saelig Company, Inc. has introduced the PicoScope 2-channel 9402 Sampler-Extended Real-time Oscilloscope (SXRTO) series with two models available: the 9402-05 and the 9402-16 with 5 GHz and 16 GHz bandwidth respectively.  They complement the already available 4-channel models at a lower price point.  Designed to analyze repetitive or clock-derived signals, they feature two high-resolution 12-bit channels driven by the equivalent-time sampling (ETS) of up to 1.0TSa/s (1.0ps) for the 5GHz model and 2.5TSa/s (0.4ps) for the 16GHz version. The wide-band inputs can accurately measure transitions as fast as 22ps, pulses down to 45ps wide, and permits clock performance and eye diagram analysis of up to 11Gb/s signals (to third harmonic). In addition, the real-time broadband sampling modes can support analysis for other common RF signals such as wireless frequencies of 900MHz, 2.4 and 5.5GHz and upwards.  Pico’s SXRTO instrument architecture reduces the cost of broadband time-domain sampling for repetitive signal or clock-related applications.

In contrast to conventional “sampling oscilloscopes”, the ETS technique supports trigger and pre-trigger capture and the familiarity, convenience and ease of real-time oscilloscope operation. Pico’s SXRTO technology seamlessly transitions to single-event, real-time waveform capture at sampling rates at and below 500MS/s.  Both sampling modes capture to memory of 250,000 samples, beneficial for capturing slower system signals, modulation envelopes, and repetitive pulse patterns.

The USB-controlled PicoScope 9402-5&16 are supplied with PicoSample 4 software, a free touch-compatible GUI, which controls the instrument and presents waveforms, measurements, and statistics on an attached PC display. There is full support for available Windows display resolutions, allowing the inspection of waveform detail or presentation of measurements, for example on 4K monitors or projection, or across multiple monitors.

A wide range of automated and user-configurable signal integrity measurements, mathematics, statistical views, and limits test facilities are included for validation and trending of pulse and timing performance, jitter, RZ and NRZ eye diagrams. Industry-standard communications mask tests such as PCIe, GB Ethernet and Serial ATA are included as standard.  PicoConnect® 900 Series gigabit and microwave passive test probes are recommended for use with the 9402-x, offering a range of bandwidths, division ratios and AC and DC coupling for diverse applications. The PicoScope 9402-x scopes have an active SMA interface to support future configurations and accessories on this product architecture.

Typical applications include: telecom and radar test, service and manufacturing, optical fiber, transceiver and laser testing, RF, microwave and gigabit digital system measurements, signal, eye, pulse and impulse characterization, precision timing and phase analysis, digital system design and characterization, eye diagram with mask and limits test up to 8 Gb/s, clock and data recovery at up to 8 Gb/s, Ethernet, HDMI 1, PCI, SATA and USB 2.0, semiconductor characterization, signal, data and pulse/impulse integrity and pre-compliance testing, etc.

The 9402-x is compact enough to place on a workbench in close proximity to a device under test. Made by Pico Technology, Europe’s award-winning test and measurement manufacturer, the PicoScope 9402-5 and -16 oscilloscopes are available now from Saelig Company, Inc. their USA technical distributor.

One of the major factors while considering this board is the support for video codec. If you are into video transmission or similar projects, this might aid your application as it supports MPEG-1, MPEG-2, MPEG-4, H.263, H.264, AVS, VC-1, VP8, MVC, which is incredible.

This credit card-sized high-performance development board is a DIY product specially for teenagers. However, the XPI-3288 development board is priced at $75 and is currently available for sale on the official product page.

18650 LiPo Battery Manager for Remote Applications

The 18650 LiPo battery manager comes with a fuel gauge and a dual-rail power supply. The dual-rail power provides a 5V rail along with a 3.3V rail dedicated to powering the microcontroller and the display ports of the system. It is termed as an “all-in-one single-cell LiPo battery manager” by Manuel Alfonso for its flexible compatibility with all types of single cells and its various functionalities for battery monitoring operations. However, the 18650 LiPo Battery Manager is dedicated to a form factor that can act as an add-on at the back of the 18650 battery box. Hence, it can be used as a power bank for various projects.

18650 LiPo battery manager features a bq24075 IC from Texas Instruments for battery management and monitoring functionality. The maximum charge current can be controlled via the DIP switch, which outputs 1A, 500mA, and 100mA current readings. The combination of the pin status determines the maximum current value is shown in the table below:

The bq24075 chip’s Dynamic Power Path Management (DPPM) makes the output active “whenever a source is connected to USB or BAT, guaranteeing power to the project even if the battery has died. The input current from USB is shared and balanced between charging the battery and powering the system load at OUT.” In Battery Supplement Mode, if the output current exceeds the limit configured by the DIP switch during the charging process, then the battery provides the system load without any regulation. Hence, the maximum current can be drawn in any condition.

18650 LiPo Batter Manager 1

The 18650 LiPo battery manager supports the BQ27441-G1A fuel gauge featuring the Impedance Track Technology. It efficiently predicts battery capacity and other operational characteristics with utmost accuracy. There is a delay of a few seconds for the display of accurate data after powering the board because the IC is in sleep mode and it takes some time to wake up. When there is no load on the output pins, the actual consumption by the MCU and OLED display is shown on the display.

The source code for the system is written on STM32CubeIDE. Toolchain and IDE could be altered from the project manager tab for switching the IDE using a different file from STM32CubeMX. For more information regarding software support, you can visit the GitHub repository for 18650 Manager.

The 18650 LiPo battery manager board is available for $20 USD on Tindie. For more information, visit the product page on Tindie.

E-radionica’s Inkplate 10 is suited for your e-paper typewriter

Inkplate 10

After raising 926% funding on e-radionica’s new design of its first e-paper display – Inkplate 6, the manufacturer has continued its product range to announce the Inkplate 10, an upcoming low-power, easy-to-program open hardware that can come with Wi-Fi support. This upgraded e-paper display is listed for crowdfunding on CrowdSupply with the goal of $12,900.

Compared to its predecessor, the hardware comes with a 9.7-inch display and high screen resolution of 1200×825 pixels with 1.61 second refresh time in black & white mode, and 1.81 second refresh time in grayscale mode. This powerful and energy-efficient design is based around the famous ESP 32 WROVER module, a dual-core microprocessor providing 8 MB RAM, 4 MB of flash memory, and support various wireless communication protocols, including Wi-Fi and Bluetooth 4.0.

Inkplate 10 Product

With its minimalistic design, the e-paper display packs a rich set of interfaces including the USB Type-C port that can be used for programming as well as to power the hardware. The display has additional GPIO pins that come along with support for I²C, SPI, and easyC/Qwiic connectivity. To increase storage, you get an optional MicroSD card reader for storing images to be displayed.

Thanks to the low power consumption that achieves 22 µA sleep states allowing it to last for months on a single battery. To add more to the hardware part, boost with three capacitive touchpads – usable through the optional enclosure. At just 23 x 18 x 1 cm and weighing 260 g, it adds more features than you would ever want at $139.

With easy-to-use experience in mind, the designer has supported the display with Arduino IDE, MicroPython, ESP-IDF, allowing you to just “plug in a USB cable, open the IDE, pull up some sample code, and click upload”.

If you like a good old-fashioned Arduino IDE, our library will have you rendering your own images in five minutes. For higher level programming, we also maintain a MicroPython module that’s just as easy to use. And for the hardened ESP32 programmers out there, we also support ESP-IDF.

If you are interested, the product is up for crowdfunding via Crowd Supply, priced at $179 for the display with a 3D printed enclosure.

This Compute Module 4 Hunter is set to challenge Official CM4 Carrier Board

Compute Module 4 Hunter

Swiss-based founder of Quick-Pick AG, Andreas Eberle, has designed a complete Raspberry system with hardware and software utilizing the power of Raspberry CM4 that lets you use interfaces and industrial communication protocols without the need to buy any additional HATs. This Compute Module 4 Hunter is up for crowdfunding via Kickstarter with the goal of $15,490.

The release of the Raspberry Pi CM4, integrated with the quad-core Broadcom BCM2711 Cortex-A72 chip, lead to the unveiling of the official carrier board to cover all features required. However, the aim of the CM Hunter project is to extend the functionalities through a smaller form factor.

This 4 layered PCB, sizing 79x97mm integrates all the common communication protocols used that include,

  • RS485/Modbus isolated
  •  CAN 2.0B isolated
  •  1-Wire isolated
  •  HDMI 2.0
  •  ETHERNET Gigabit
  •  USB 2.0
  •  2.4 GHz, 5.0 GHz IEEE 802.11 b/g/n/ac wireless  /some CM4 versions/
  •  Bluetooth 5.0, BLE /some CM4 versions

Compute Module 4 Hunter hardware

Supporting all the above protocols gives the user a wide scope of use in various domains.

“You could use this platform for reading sensors, protocols and sharing data files between all communication modules, storing data on USB stick, Cloud servers, etc.”,

the designer notes.

To power the board, the manufacturer provides a 5V USB power adapter like the one you get with your smartphone (delivers at least 2A current). The carrier board is marketed under the highlight of ‘Isolated Communication Modules‘. The integrated MCP2515 CAN controller is used as a serial communication bus for robust and flexible performance in undesired environments.

Compute Module 4 Hunter Fan

If you are working on heavy applications there is a high possibility that requires full CPU power. This, however, leads to heating of the hardware and eventually loses its efficiency. To avoid overheating in such scenarios, the hardware gets a fan driving circuit on board. A 5V 30x30x6mm Maglev FAN that is capable of keeping the CPU temperature below 50 degrees Celsius can be attached. Important to note that the cooling fan is not included in the package and needs to be bought separately.

As mentioned earlier, the Compute Module 4 Hunter is listed for crowdfunding on Kickstarter with a pledge level starting at €10 with no benefits. Going forward, you can get the carrier board for €99 and more.
