Ideally, it would be possible to throw another shaska with an inexpensive CR on this kin, just in case. It happened to me that with such a high power supply of the CR, the micro flew away during the transition of the PSU to the 10.0.0.0.1192.168.1.254 DR and the power supply voltage of the CR increased without load - I had to crush the output voltages of the PSU as much as possible and use the highest-voltage analogue of the personnel m / s that I found on sale.
