Most likely, the person did not understand what a Fork is and why It is needed. So, we analyze why you should choose a Fork, and not 20 microcontrollers.
Let's go through the entire process of creating a test stand from the beginning to the end. We give ourselves a head start, and think that we live in an ideal world where everything is done the first time, and also remove the preparation of TK(we are in an ideal world).
It all starts with coming up with a scheme of the stand - how we will test this or that feature. At the minimum time cost, it will take us a week. Of course, the time may be reduced if you sleep and see your test stand, but it is always better to get the opinion of another person, so that the ready-made stand really does what you need.
The scheme was invented, drawn/created, and now we need to separate the board. This takes from 2 to 5 days. And even though we agreed that we consider everything to be the standards of an ideal world, there may still be joints in the wiring that, in a good way, we need to check. And fix it. And this is still time, plus or minus 7-10 days.
In total, we have already gathered for 3 weeks in an ideal world, and this is not only we have not tested anything, but we have not even completed our stand.
The board is made, the microcontroller is purchased (we take into account the time for delivery of parts, or for a personal shopping trip - 4-5 days). We begin the establishment of the board, i.e., with a soldering iron and an oscilloscope, we check all the nodes of the scheme. This will take 1-2 days. Then the most interesting thing begins - somehow you need to "communicate" with the stand and get measurements from it in an adequate form. To do this, you write code that takes another week.
Thus, if you calculate the total time spent, you get a month with a tail of only preparatory work. And as you know, time is money, and in production, the person who does all this receives a salary(from $$$ to $$$$ - enter the figure yourself).
