VESC HD-60T detailed specs (auxiliary power)

Hi! 

I have two VESC HD-60T which I use for a project driving 4 motors, a couple of servos and a Rasberry Pi 4B. I try to figure out if I need additional auxiliary power or if the built-in converter is enough. 

As for the specs I only find the information given by Trampa (https://trampaboards.com/vesc-hd60t-twin-p-29152.html):

- 5V and 3.3V supply for external devices

Does anyone know what DCDC converter chips the HD-60T uses? Primarily the 5V converter. Would need a total of 6A, or 1.5A per motor unit. If the https://github.com/vedderb/bldc-hardware/blob/master/datasheets/tps54160.pdf is used here too, that would in other words seem to be just enough. 

Also, do you anticipate any problems with interconnecting the 5V power from each of the 4 units? Thinking adding a diode to each of the 5V outputs and having a common ground. Not intending on connecting the grounds in more places. Guess it would mean that the negative side of the 4 batteries powering the VESCs would become connected as a result.
