Hello, I ordered and received a OAK-FFC IR from the Luxonis shop website. I cannot find any details on how to correctly hook this up to my OAK-FFC 4P though. The [shop page](https://shop.luxonis.com/products/oak-ffc-ir?_pos=1&_sid=41fba82f7&_ss=r) does not include any documentation links. Any links, docs, pictures, videos, code samples, etc… would be greatly appreciated!

Hi @"hcwiley"#p8281 The IR module should be connected as displayed on the image: [upl-image-preview url=https://discuss.luxonis.com/assets/files/2023-05-16/1684262337-53945-image.png] Hope this helps, Jaka

(note that only newer revisions (R5+) of the OAK-FFC-4P actually have this connector)

Ok, so the OAK FFC 4p I ordered at the same time isn't the [URL=https://i.imgur.com/nMjQWyO.jpg][IMG]https://i.imgur.com/nMjQWyOh.jpg[/IMG][/URL] right revision of the board? There's no mention of this on the page, so that's kind of frustrating. I've now ordered two of the OAK FFC 4P, 2 pairs of 9282, and 2 of the OAK FFC IR. And apparently, y'all sent me the old revision of the OAK FFC 4P without any ability for me to select the latest revision. Can you point me toward the relevant schematic change so I can see about wiring this IR board into the OAK FFC revision that I have? I have a hot air rework station and can assemble what I need to make it work. Or, I'm happy to exchange my whatever revision I have for the new version that actually supports this IR board without intervention.

Hi @"hcwiley"#p8346 , Correct, you can see on the PCBA it's `R4M1E4`, and since `R5...` we have added the support for FFC-IR. Please send an email to support@luxonis.com, I believe we can replace the FFC-4P to the latest ones. Thanks, Erik

hey @"erik"#175 is there any possibility for me to rewire in my shop? One of the reasons I was interested in ordering Luxonis parts is due to the open-source hardware. I don't see any revisions of late on the FFC 4P directory: https://github.com/luxonis/depthai-hardware/tree/master/DD2090FFC_DepthAI_4-camera_FFC Am I missing something? Did y'all change the location of where the schematics changes are being tracked?

Hi @"hcwiley"#p8379 , I think we just forgot to update the designs to the latest, will ping the HW guys to push these revisions out:) I am not entirely sure, but to me it would seem PITA to try to solder wires to different test pads to get the "final cable" out that you can connect the FFC-IR to.

PR here: https://github.com/luxonis/depthai-hardware/pull/400

It looks like the [BOM is incomplete for this revision](https://github.com/luxonis/depthai-hardware/blob/09da77c10fe866e2a91fa5ba56fa7a8dde66ca32/DD2090FFC_DepthAI_4-camera_FFC/Docs/Assembly%20Outputs/BOM/BOM-DD2090_4CAM_FFC_ACTIVE_BOM(Production).xlsx) There is no J12 listed in the BOM and that is the connector that is being used for the IR projector. Am I missing something? [upl-image-preview url=https://discuss.luxonis.com/assets/files/2023-05-24/1684943387-57344-screenshot-2023-05-24-at-104925.png]

Hi @"hcwiley"#p8569 Check this [BMO085 version](https://github.com/luxonis/depthai-hardware/blob/master/DD2090FFC_DepthAI_4-camera_FFC/Docs/Assembly%20Outputs/BOM/BOM-DD2090_4CAM_FFC_ACTIVE_BOM(Production_BMO085).xlsx). Hope it helps, Jaka

I received my new board today and it is rev 5! hooray! are there any more resources you can share with me about using this projector @"erik"#175 or @"jakaskerl"#1112 ? I would love to see docs on setting this thing and how to configure the python SDK to control it. I've been re-reading the [frame-syncing docs](https://docs.luxonis.com/projects/hardware/en/latest/pages/guides/sync_frames.html#hardware-message-syncing) to see if it covers but not seeing anything.

Also, please wear high-quality IR-blocking glasses - lasers are no joke, especially when not tested (without front glass)

The projector is not turning on, I cannot see any IR light coming from it. That modified script code is successfully executing that's good.

Here are some pictures of my setup to help clarify. I have a RPI with an known IR sensitive camera running so I can check if IR is being thrown around.

I'm trying to use my OAK FFC 4p with OAK IR to project a dot pattern

No matter what setting I try the OAK IR will not turn on. I am powering the OAK FFC 4p off the provided power supply, so it's definitely not a power issue.

Hello @erik,

Have there been any updates to this thread? Our modules are due to arrive this Thursday and it appears we will be in @hcwiley's same position.

Hi hcwiley / AlexHendren ,
Sorry about the delay, it was super busy during a conference. What's the current you set the projector to? Hopefully it was high enough, as below 200mA or so, it's not even visible.

hcwiley

No word so far. I'm not sure what else I should be doing here. I can put a scope on the lines going to the IR and see if it's getting a signal. I would love to not have to do this though!

hcwiley

I've set it to max of 1200 and it has no effect

hcwiley

hcwiley FPS: 30.23| 30.00Dot projector brightness: 1100 True

I added a print statement after setting the dot brightness to see the return value.

The API is recognizing and returning true that it is setting the brightness

hcwiley

Hi @pzhine ,
Sorry for not clarifying - it's BP @ 940nm, so same wavelength as the dot projector/illumination LED. So that way the sensor would perceive visible light + 940nm.
