Version 2 parts soldered :)
more powerful DSP and ARM + memory ( underside )
ADC and DAC cards are now plugin BUSA & BUSB
On board ARM debugger on underside of board.
only 1 x uSD card because I ran out of DMA capable pins on the STM32F7
but have since discovered if I use a different revision of the chip without DSI
there are more pins available for second uSD card for recording redundancy.
SPI is for analogue pre-amp control
BT for BT module
I am now working on DSP mixer design for new DSP chip & firmware
to be done:
redesign analogue back plane for pre amps and driver cards
design the AES3 IO card option
think about what kind of file system I should use for recording. currently FAT
