Hello Guys,

for updating to the test board to support the CM3 you will need to change the power chip to the one that is listed on the CMIO schematics on the raspberry pi page

Hello, Guys, First of all, thank you Briarios for this work. Could you explain a few words, why do you recommend using 4 layer setup in Eagle? I know that it is possible with 2 layers as well, and I have some experience with 4 layers. What I don't really get, is how did you planned the layers? I me...

Briarios

Hello Ian, your best option is to download the Board files and then send the Gerbers to your favorite PCB House for them to do the manufacturing. As it will be really expensive for me to send you a board :oops: to give you a quick idea the cost of a single populated board is about $110-150USD as tha...

May want to check what you're quoting guys as it appears to some that I am the bad guy for starting the war

May I suggest allowing the pi community to design the board and then the foundation to vet and confirm the designs?

Briarios

Let me see on what i can do on your idea and get back to you

though may take me a couple of days

As your idea is a pretty good idea

Briarios

Hello again everyone, I have finally managed to put all the parts together, and unfortunately I don't have the steady hands needed for SMD soldering/re flow so there are lot of solder bridges that i can't seem to clear. here are 2 pictures of the finished board anyway so you can see on what my idea ...

Briarios

do an update with rpi-update and see if that solves the issue. other than debug i am not sure what else could be a problem.

Briarios

Hi I don't know if you're still active on this project or on this forum but I'm currently working on a project using your testboard as a template. However, I'd like to add in HDMI and a wifi module and I'm not sure how I might approach this as I'm still new to PCB. Any suggestions will help! Thanks...

Briarios

Solder paste has arrived

so I will be putting stuff together sometime this week and hopefully testing next week haha

Briarios

just a small update. I am waiting on key tools to build this board. I had hoped they would show up last week but nothing yet. Just to let you know I have all the parts and PCB's just now waiting on some tools to get this Prototype up and running.

Briarios

I would suggest to do a reflash with an older version to see if that would work.

Hey Guys, Sorry about the delay, but most of the parts needed have come in :D so I am waiting on a couple of key parts which should be here by the end of the week. but for the time being here are some pictures of the PCB and Stencil and the small smd components 8-) Sorry for the pictures the lightin...

Briarios

Hello Everyone, Sorry for the delay, I had to be in work/life mode for the last week 8-) but just to let you know I haven't forgotten about this and I am just letting you guys know that I have the Blank PCB's made up and they should be arriving in a week or so. once that is done I will then start po...

I could see it being useful for very specific scenarios, but I personally won't need one. The cost of the hat, plus a power injector or PoE-capable switch makes it a bit expensive for my uses. :D I will say having POE won't be for everyone, but there will be some people out there that will like one...

Briarios

It could be interesting, at the right price. I think this is the reference base price for a POE solution: £15.70 http://www.amazon.co.uk/TP-LINK-TL-POE200-Power-Ethernet-Adapter/dp/B0038X3RVA Being 802.3af compliant will be essential in some cases, so that adds value in those applications. Adding a...

Briarios

Why to leave existing ethernet connection unused and duplicate it in the HAT? :) Good question. some people would like to use an A+ as a remote device other people would want to use a device with 2 Network interfaces. I would like to cater to both :D hence why I would like to have a duplicate netwo...

Briarios

I will have to say that those are nice idea's for getting POE onto the raspberry PI. but while they both do similar jobs in splitting the power from the data and then forwarding the data to the PI's network port, what my idea is to have the data go directly into network IC similar to LAN9512 on the ...

Briarios

Hey Guys, I am just doing a Poll to see if there is any interest in having a POE Hat made? As I am thinking about designing a Hat for the A/B+/PI2, the hat will have or hope to have the following items. a) 802.3af compatible POE device that will have the ability to power the Pi via GPIO Max (2Amps)....

Briarios

Ok Just to provide an update. I have sent my designs off to get a quote from a Fab house in China. So i am waiting on a reply, As they have a labour day long weekend this weekend I probably won't hear from them till at least Tuesday.

Briarios

The Only breakout board that I know of that will give you access to the pins is the devboard that comes with the Compute module.

Briarios

Hello Visualecho, tis a valid question you have hmm... I had a look at doing a 2 layer board for the Test board. But after some investigation I had found that the traces for USB and Ethernet would be relativity large for the space I had allocated for it, therefore and after reading documentation abo...

Briarios

Ok So i have had a look at the Switch IC you have posted RaTTuS and while it is great i'm afraid that i can't use it at the moment. I will stick with the Original Realtek chipset for at least the initial Prototype as i have it setup and will think about switching to a Gbit Switch IC once I have conf...

http://www.davicom.com.tw/userfile/24247/DM8806ProductBrief_v1.0_080511.pdf is one that I found this is something that I would consider kickstarted ;-p Thanks for the link RaTTuS, if you have any schematics on it would be great :) but I will definitely look into that and see if I can get that or so...
