Hi Ron

Is very expensive, I mean, pcb size and ICs prices (the USB host controller
is more expensive than Ingenic processor), we can use an external peripheral
conneected to Data, Address and control CPU bus, but this increase the
At present SAKC board is a two layer board, I'm using TQFP chips, so any can
build the board.

You're right, right now I'm designing SAKC for the new Nano version AVT2,
this board have one USB host port.

But, I think that we can use the FPGA on SAKC board to emulate a SD
compatible device and connect with BEN.

 The goal of SAKC is supports all sorts of plug-ins

The  FPGA is ~THE~ distinguishing feature of SAKC

You're right, At present SAKC board has 25 Digital In/Out signals and 8
analog inputs.

I think that the best choice is make the manufacturing process in China,
Here in Colombia is expensive.
