Hi

Newby to SBCs here.

Are there any prototyping boards available for the GPIO ports for a A20-OLinuXino-LIME2?

I'm thinking something like this which is for Raspberry pi

Thanks!

I feel a bit thick for having to ask this. But looking at the schematic the LIME2 shield product has a line in input but no ADC. My understanding is that the A20-OLinuXino-LIME2 has no ADC itself which is why I was looking into adding an ADC, so how does the SBC take in the analog signal? I must be missing something obvious!

A20 chip has two ADCs but they are not very good - 6-bit, input 0-2V, usually used for buttons. Check the datasheet for LRADC.

You can check also MOD-IO and MOD-IO2 boards if you wish to expand the analog capabilities of the board.
