I want to control two hitec hs55 micro servos via a Nodemcu v3. These need at least 4.8 V power supply acc to data sheet.
Hs-55 micro servo:
Voltage range: 4.8-6 V
Current Drain - no-load (4.8V): 150 mA
Pulse Amplitude: 3-5V
From what I found it seems like it can "reliably supply 600 mA".
3.3V pins (standard)
5 V (pin VU), Directly connected from the USB (?)
From what I understand it is generally a good idea to supply power to servos separately, otherwise the board can be damaged. Is this also the case here or would it be OK to connect the supplies to the servos from the VU pin? I'm thinking that there is a possibility it could be ok since it is directly connected to the USB.
For the signals I will use the normal GPIO pins.
Thank you in advance :-)
