Diatone PDB for ZMR 250
0I got my Diatone PDB from China about a week ago. Some of the holes do not line up, but that wasn't a surprise since I already did some measurements with members in this forum. I am surprised the PDB has two voltage regulators for 12 and 5 volts and signal lines to allow you to run signals from the FC to the corners of the board to reduce the number of wires / declutter the craft. You can run ESC signal wires or repurpose it for something else.
It also came with four led strips. I tested all four and they are different colors: white, red, green, blue.
Too many lighting options for me :). I was going to put the pdb on top of the arms, but now I'm going to put it at the bottom so I can solder the led strip to the pdb (now I have to worry about rough landings or direct hits to the pdb during hard landings or crashes).
To those who have this board, what colors are you using and for what direction.
I was thinking of putting the white leds in the front or front bottom. The former would be great for fpv with the leds lighting a path for me (like a headlight). If I put it on the bottom it would light up the ground as I hover near it.
Putting Red LEDs in the back so I know it's the rear ( like a car's tail light).
Green at bottom front and blue at bottom rear? Green means go so that's why it's fwd at the bottom.
What do you guys think?

Try rotating your frame 180 degrees - one way the holes were kind of close and the other they were perfect on mine. I didn't figure out the esc wiring traces until i had already built mine so i didn't bother - rotated the fc 90 degrees anyway so the pins and board traces no longer lined up.
I put blue in the rear and green in the front with the expectation that I'm also going to put the white strip facing forward and the red facing rear - exactly the same as what you said.
@djslack Great minds think alike.. lol. I soldered the green in the front and blue in the back. In hindsight, I should have put the esc on the arms. My quad looks a little cluttered. I decided not to use a standoff for the FC but to build a carriage for the two aluminum standoffs that will slide in. I'll put both the cc3d and the rx705 on there. I'll see if I can find a design to rip off on thingiverse or I'll design on myself of chop someone else's design and make it work for me. I'll share it if anyone is interested.
@djslack About the signal wires, I decided to use the wires instead of soldering it onto the board. Lazy I guess. I didn't think of rotating the board to see if it'll be a better fit. thanks.
@garyhgaryh If you're running the escs inboard it might have been more trouble to use the esc traces anyway, since your input side should be back near the middle of the quad. Probably more wires running across things to do it that way than straight from the fc.
@djslack It's also easier just to run the wires vs soldering them and then soldering wires to the FC. I usually go for convenience if it means less work :).
@garyhgaryh @djslack At the moment I intend to use header pins on both ends of the signal traces. I may opt to solder the ESC end once I get into assembly. After all, the power wires for ESC will be soldered, so using pins wouldn't really give me any advantage I guess. But I'm pretty sure I'll stick with pins on the FC side.
