LA1034 mictor adapter
I’ve been looking for a while to purchase a portable logic analyzer, one which has USB connection and half of the job is done by a software application on PC. There are plenty devices like that on the market with different sampling rates, memory sizes, number of channels, features, prices and so on. One important thing which made me looking for reviews was the stability of both hardware unit and software application which comes with it. In the end I decided to pull the trigger on LA1034 made by Intronix. It has been for me a trade between all the characteristics mentioned above.
In the package you can find the hardware unit, a connector with flying leads and the USB cable. The software application should be downloaded from their website, here. The hooks in the pictures are part of an additional order.
Because some boards I’m working with use mictors for signal monitoring, I looked also for an adapter, but what I found was not exactly what I was looking for, so I decided to make one. This is what I’ll describe here below, how to build your own LA-to-mictor adapter. The one I made has at one end the mictor and at the other end a typical 2×19 pins header connector, so it can be used with any logic analyzer. Using the flying leads any combination is available.
The layout is double sided, both connectors are placed inline with the pcb, which will fit the space between their pins. PCB layout is home made using a laser printer and an UV lamp. This procedure can yield layouts with line thickness of 10 mils(0,25mm) and below so I managed to get a good layout for the adapter.
Here below 2 pictures with the final version. I added on both sides a thin layer of liquid plastic to prevent corrosion. At the end I placed 2 pins on GND pads and checked the connectors for short-circuits (especially the mictor).
There are 2 formats, single and double copy. The second one is easier to fit on PCB using the 2 lines in between as reference to the start of PCB board. The matching on the other end (mictor side) is difficult but using the mictor pins as reference, can be successfully accomplished.
