Interest thread for F8-B and F32-B
« on: May 31, 2017, 07:46:23 AM »
Some of you may have followed my development of new boards for the BBB.   I've create two separate boards to meet some needs in my own show and I can make them available for others if there is some interest.   They are both "named" after the number of fused local channels available, but both have ability to drive many more channels via differential receiver boards.


The first is the F8-B.   This controller has 8 "local" channels for 3 wire pixels.  It also has one 4 channel differential output to drive 4 channels via a Falcon Differential Receiver Board.   There are two other 4 channel differential outputs that can be configured for either DMX/PixelNet or more string channels.  In addition, there is a 40pin expansion header to drive an F16 expansion board.   This board is small (9cm x 10cm) to fit in a CG-500.   I'm using this to replace my F4-B's that my show has out grown.   


The second is the F32-B.   This has 32 local channels.  It has two "4 channel differential outputs" for driving another 8 channels via the differential receivers, and another two 4 channel outputs for 8 channels of DMX or PixelNet or more strings.   It's 15cm x 15 cm which is slightly too large for CG-500 (although getting 32 outputs out of the  openings in the bottom of a CG500 would likely not work anyway), but is small enough to fit in most other boxes.  For me, this will replace my F16-B's mounted in marine battery boxes that I've outgrown and need more outputs.

Cost:  I believe I can provide a "full kit" for the F8-B for about $35 and the F32-B for about $60 (plus shipping).  That kind of depends on quantity though, if there is only interest in a few boards, the cost would likely be a few dollars higher.  It's all simple through hole stuff so fairly easy to solder.  If you KNOW you will only use 5V pixels, you can also save $5 by not installing the DC/DC converter.   Obviously it needs a BeagleBone of some sort to connect to which obviously adds to the "total cost". 


Anyway, if there is enough interest, I can run a group buy.  Otherwise, I'll just order some boards and parts for myself.

I have a few BBB/BBGs sitting here (since I started using RasPi to drive P10 panels).

I would be in for possibly 4 of the F8Bs.

I'd be in for at least (2) of the F32Bs.

Would be in for 1 of each.

Any idea on number of pixels per output?

I've personally run 490 on an output without a problem (other than tons of power injection).    The current UI limits it to 999.

Just to complicate things a bit:  I got a quote from Elecrow for the F32-B fully assembled.   If it was offered fully assembled at around $80-$85 (plus shipping) instead of as a kit, would that change anything for anyone?   Would people prefer the cheaper "kit" that involves soldering themselves (571 pads according to the quote) to save a little money or is the $20 worth it to folks to have them come assembled?   I haven't inquired about the F8-B yet.

I would be in for 2 of each, and would gladly pay $20 more to have the 32 channel board assembled.  Assuming perhaps $8 for the 8 channel, my preference would also be to have it assembled.  We still have the option to repair them in the future, but my time is more valuable at this point in my life.

I would be interested also in 1 or 2 of the f8-B pre assembled and maybe 1 f32-B assembled

I would also be interested in the assembled boards.

In the past sure I loved doing the soldering, but now I actually like the assembled.
