If possible, I have one more question.
In the photo below there is a missing element, from pin 6 of the microcircuit to ground (pin 4). In the datasheet, to turn on, pin 6 is connected to the power supply with a 604 kilo-ohm resistor, in my case it is the same, only there is also a resistor to ground. On the neighboring microcircuit, which is 3.3 volts, there is the same resistor, I unsoldered it to measure the resistance, but it turned out to be open. According to the datasheet, it should work stably without a resistor with a pull-up to ground, is it necessary to install it and if so, what value should I set? 10 kilo-ohms should be enough, I think. On the 5.0 and 5.2 volt microcircuits, there are no such resistors, since the controller controls the switching on there.
