Need a BeagleBoard with ADC pins

Hi,

i'm new with these stuff, previously i'm more into PIC Microcontroller
(Microchip). i have my eyes on SBC, searching for higher performance
embedded system.

is there any BeagleBoard products that have 32 ADC inputs? please show
me... or is there only 2 development boards? (BeagleBoard-xM and
BeagleBone)

if so, is there any possible way such as using any expansion board so
i can get 32 ADC inputs by also using the BeagleBoard-xM as host?

Thanks.

None of them have 32 ADC pins on them. But you can add then via SPI or I2C. You can do this on the BeagleBoard, BeagleBoard-xM, and the BeagleBone.

I have a extension board design (the BeagleDAQ) which sadly has no
website currently due to our broken academic publishing system. The
board has support for four 8-channel 16-bit ADCs capable of sampling at
200kHz (although realistically you'll be getting a few kilohertz at most
due to bus constraints). If you want a board, we can talk. If you can
reduce your channel count a bit, there's also the PandaDAQ[1] which Mark
Haun and I have been slowly working on which I intend on eventually
using in place of my BeagleDAQ design.

What DAC acquisition rate can you get on a beaglebone?

My gut instinct tells me that what you want is a beaglebone with a mux shield/cape.
Arduino has something similar…
