Duh! Why didn't I think of that...? (and I'm being serious...) I do the same on the other boards I follow... I'm still thinking of how I want to build it... I'm transferring all the parts from a Robocat 270, but not sure what I want it ti look like. I think I and going to 3D print spacers and make it clean... we'll see...

Ok... more questions....

I ended up getting the 5V and 12V converters from Pololu, and soldered up everything just as it is in the assembly video, EXCEPT without the OSD. I then see towards the end of the video that the wires for the Vtx (I assume...) are soldered to the "ground" and "video" near the OSD. So in saying that:

1. Where does the power from the Vtx come from, since there's only 2 wires?
2. If I don't use the OSD, I would just run the video right from the camera, no?

And on the camera connector at the front...
1. Again, if I don't use the OSD, does the video wire go direct to the Vtx?

Sorry if I should know the answers to this...

No problem,
The power for the VTX depends on the voltage it needs. Most folks would just power the VTX directly from one of the LIPO voltage pads such as the battery pigtail spot.

If you don't use the OSD, just connect both sets of jumper pads on the bottom of the PDB, that will connect the video pad you connect the camera to directly with the video pad in the back.

Connect both sets shown here:

Ahh... ok... So if I bridge those 2 pads, I can go from the "Video" up front to the "Video" near the buzzer? And I assume the "LiPo" pins, either one, can be connected to VBAT on my FC? And the 5V and ground next to the buzzer will power my FC I assume... I've been looking through the attachments in this thread...

EDIT: This image pretty-much shows what I'm going to set up, and I see the Vtx (which happens to be the exact one I'll be using) is connected along the side, instead of towards the back near the buzzer. So does that side Vtx connection connect to the front camera connection somehow?

Hi
Building my first ZMR Quad .

3S setup with following parts:
Parts on order:
Motors- Racerstar 2205 2600kv
ESC- Racerstar 20a BLHeli_S OPTO 2-4S
PDB- Simple PDB

My quad will be built only with components to get it to fly.

My ESC's don't have BEC so would like to know please which and how many voltage regulators I should get .

Would there be a wiring diagram for my intended setup?

Thank you

Rick

was about to link you to this thread in the ZMR thread, glad you found this. There are tons of resources for getting this board working here!

My board has been shipped. Looking forward to seeing it .

Meanwhile, I've gone through all the pages here to acquaint myself with the project ahead of me. Ive made copies of your color coded schematics
for reference.

I'm planning on doing layout of this board with the components for my build for review and comment.

I still need to get FC and determine which voltage regulator ( s) to use.

Cool, I look forward to seeing what you put together!

Heres my diagram of PDB and photo of FC ( from distributer ) is provided to help identify various connections

This build will only have what is needed to get the quad flying. No plans for FPV .

This is my guess as to what it will look like . I added Pololu 5v Vreg thinking it will be needed.

The LiPo ( + G ) connection on PDB to FC is in question.
Need to verify gauge of wire for motor 1-4 connection at FC to PCB.

Please provide your comments and suggestions.

Thank you

Just regular servo wire for the motor connections, I'm thinking they're 22g.

This is where to connect the LiPo voltage. You can skip the ground connection as you'll already be connecting the ground to the board in other spots.

Thank you for looking over my sketch and providing your input.

Wow... the first post in over 3 months... I hope someone is still around to answer my question/issue...

So I got the PDB wired up exactly like the video, with the voltage regulators and such, and soldered on the ESC's. Then I soldered on the battery connector and fired it up. ESC made their tones and no magic smoke...

So I'm ready to connect my FC (SP Racing F3) and, lucky for me, I listened to just about everyone here and used a multimeter to check voltages. The weird thing is that I get 16V (minus decimals) to both Lipo connectors and all 4 ESC's. any other place on the PDB that I'm supposed to get either 5V or 12V reads 0.0000. What did I do wrong? I took my time soldering, and I think I did a pretty good job at soldering the pins for the regulators. I just don't know what I did wrong.

Oh, by the way, I'm using a 4S 1400mAH battery.

For now, to get this build finished, I am going to piggy-back off of one of the Lipo connectors and use a 5V step-down to power my FC.

Any thoughts?
