Powerboard V4 vs V9

[Deniz M.]

Hi everyone, 

A newbie here, while trying to purhasing the parts I actually ordered an older version of the powerboard (v4), believing that this is the most up-2-date version since actually there is a seperate sheet in the master BOM file called Powerboard. And now I digged a little deeper while building it and found out there is a  9th version of the board, I noticed that there is not much difference in terms of voltage levels (in the end all i need is constant 12V DC for Jetson and Hokuyo, please correct me if I am absolutely wrong here). 

TL:DR

In brief, is there any real/practical difference betwen these versions? Would I be messing up things in Slash+NX combo with a v4 powerboard?

Any help is more than appreciated.

Thank you all in advance.

Hello,

   honestly I am not sure about the differences, but if you share the sources you have used, I might be able to tell you that. From what I believe, there were not many changes after v3.

Best,

J.

The v9 uses surface mount components and you need to use a reflow station for some of the parts. I successfully built a couple of v9 boards but it was definitely more difficult and time consuming than a v4 board with thru-hole components would have been. If you already have the parts for a v4 board and you only need 12V then that is probably the simpler path.

• I am building a { SLASH + NX } 
• I will power:
  • NX => 12 Volts DC via powerboard
  • LIDAR (10LX) => 12 Volts DC via powerboard
  • Realsense d435i => USB power (5V 1A i guess) via NX 
  • VESC 6 MKV => battery voltage via y-splitter battery power cable (1 goes to VESC, other connected to powerboard)

• The master BOM file I referenced to: Powerboard sheet (v4)
• OSH Park PCB docs: F1/10_Powerboard, V4.0

• SS of what I have built i.t.o powerboard and its descriptions:
  • Regulate battery (3S LIPO 5000mAh 11.1V) voltage  to 12V (‎102-3892-ND‎)
  • Regulate 12V to 8V (BA7808CP-E2CT-ND‎)
  • Passive circuit elements to help filter output voltage.
  • A LED indicator of output voltage is OK.
  • Cant find (waiting for a digikey order) 2.54mm 2 Pos terminal blocks in my region, so I had to go with these output connectors (called tunic connectors in my region).
  • Cant find (waiting for a digikey order) a toggle switch with 2 pins, so I had to short it for testing purposes.

I don't know why V4 has 8V output, not 5. I am hoping to try a 5V regulator. What advantages does V9 have?
