I am involved in a project to take the BBB and re-design a few parts of it to provide the following functionality :-
-
2 off Gigabit Ethernet channels.
-
1 off 10 / 100 Ethernet Channel, (this could possibly be done using a 48 Mbit/sec SPI link).
-
A minimum of 4 in, and 10 or 12, (more if possible), out, Audio channels, (probably through one McASP I/F)…
-
24 bit LVDS LCD I/F, using as few I/O pins as possible. We do NOT want the HDMI I/F.
-
4 wire resistive Touch I/F.
-
Keyboard input, serial preferred, USB if necessary.
-
A VGA output would be very useful to complete the Debug I/F.
-
3 off RS232 or 485 Serial links.
-
At least one PWM output, to drive the LCD Backlight.
We want the board to be a “Plug in Module” with all I/F’s going to 0.1" pitch pin headers of some sort, with the probable exception of the Gigabit Ethernet connections. The Carrier Board would provide power supplies, Audio Convertors / Codecs, etc.
We’d like the board to fit on a maximum sized PCB of 100 mm x 140 mm.
The AM3359 has 8 sets of permissible configurable I/O combinations, so one thing we would need to know is “can we have our shopping list within one of the permissible configuration sets ?”.
We’d like to know first of all if our shopping list is feasible, and if so we’d then like to ask if there is anyone out thee who could help us with this design work, particularly with some estimates of the time and costs involved in getting a small batch of prototype boards made up.
Thank you for your time and attention, I hope to hear from somebody soon
