Yes. Make sure to double check that the pinout/wiring is correct

2060-452/998-404 | DigiKey Electronics Order today, ships today. 2060-452/998-404 – 2 Position Wire to Board Terminal Block Horizontal with Board 0.157" (4.00mm) Surface Mount from WAGO Corporation. Pricing and Availability on millions of electronic components from Digi-Key Electronics.

I am not sure about the pin spacing but it's probably a variant of Wago's PCB terminal block series.

Isometric projection view of the ceramic module.

Top view of the ceramic module. The LED dies for each alphanumeric character are arranged in a 5x7 pattern. There are two IC dies at the bottom of the module. The black squares are possibly resistors. The dark grey rectangular object in the middle left of the module is a ceramic capacitor.

The module with power applied. LEDs in rows 1 and 7 are on.

I recently got this mil-spec ceramic hybrid alphanumeric LED display module. Hopefully I'll be able to figure out how to interface with it in a reasonable amount of time. It likely will require some sort of serial interface though so hopes aren't high. Neat thing to look at though.

Is the converter a TPS63070 or similar variant?

The pins of the IC are being aligned to the board's pads by the pogo pins.

The acrylic cover pushes down on the IC so that its pads make contact with the board's pads.

I made a breakout board for a realtime clock IC featuring an embedded TCXO. The IC is temporarily held in place with pogo pins for alignment, and a piece of acrylic is used to help press the IC onto the pads of the board. This allows me to program the IC for use in another PCB project.

Interesting. I would assume, at least for professional equipment, the manufacturer would rather the user buy their 4-port model or switch matrix than just have the ability to easily use software on a lower tier model.

Oof. Hopefully that clock wasn't expensive.

Many years ago I started soldering using these kits: theelectronicgoldmine.com/collections/...

Grasping at straws here but maybe try putting a load on it and see if the output voltage becomes 5v. Some regulators need a minimum load to correctly output the set voltage.

Yes. It's good enough to be a substitute for a press fit implementation.

Screenshot example of a footprint using offset through-hole pads in a layout program from a random forum

One way of dealing with the alignment issue of soldering headers - if you have control over the PCB design - is to make the holes offset from one another such that the pins of the header will be snug against their respective through hole pads.

Thank you. Yes, I designed the PCBs myself. They were made by OSHPark.

No problem. Hopefully you'll be able fix it without much hassle

My initial approach would be Physical integrity of the USB Connector -> Power rails -> Clock sources -> USB Controller

Back view of the box looking at the modified fans to take in air through a filter to create positive pressure

Angled view of the box which shows area to place hand into

My lab room is usually dusty so I got a dental dust box and reversed the fans (for positive pressure) to create a pseudo "clean room" box for certain electronics assembly/testing procedures which require a more dust free environment.

Exactly. The circuitry was limited to the center of the flexible printed circuit board. The rest of the board was void of any parts except for some thin meandering traces to act as a make-shift deformation sensor.

For the prototype, I remember cutting the tennis ball in half and then making a circular flexible printed circuit board whose circumference extended up to the outside edge of the ball. The ball is just glued been together. Soccer ball may be harder because it still has to be air tight.

I had a similar idea in college but it turned out to be a dud due to the amount of deformation the ball undergoes when it is in play. The battery is the biggest problem. I remember my prototype efforts were cut short when the battery ignited.

Return loss of RF Connector is quite good.

I got my hands on one of those solderless mid-board launch 30 degree RF connectors. This is for future use in messing around with designing a PCB using distributed elements without having to solder connectors for testing. The initial "best guess" mounting footprint shows good return loss.

My last guess here for the time being. Lol. Is it for measuring directional power?

With the diodes there my thought would be some kind of variable attenuator assuming a two-port system with the 2-pin header being in place for supplying the bias voltage. Less likely something like a switch or balanced mixer.

Is the bottom right a quadrature hybrid coupler?

I would suggest getting an iron that uses tips which have the heater integrated as the response to load is quicker and the temperature is generally more accurate.

Been in a similar situation before. Are you able to make the front panel out of a different material like PCB?
