Dear Sir,

I want to know which Board is most suitable to acquire bio signals(in terms of voltage) and to display same and need to control some peripheral according to signal after process, if the board is compatible with MATLAB then it will be advantageous

Hi,

What are the voltage ranges in question?

To be more specific - are you looking for a Sitara processor that can do this or for a precision ADC?

I am looking for sitara processor and voltages in term of -0.05 to +0.05 v

I'm afraid that none of the ADC modules inside Sitara devices can fulfill these requirements. Sitara ADC's are 12-bit and can measure voltages in the 0V - 1.8V range. I think you will need an external solution. Here is a link to the TI ADC product page: www.ti.com/.../data_converter.page

AM335X GP EVM and Beaglebone Black, and AM437X GP EVM all have ADC inputs available on external connectors. AM57X processors do not have ADC modules.
