Brainstorming Improving Next Version Of digiX Board

(1/4) > >>

gogol:
I open this thread, as digging into the digiX, I stumple upon some questions, which could be improved or extended in one of the next releases.
For an better overview in cases this thread grows over the month, I recommend the following edit rules:

* Post for each new suggestion one message with own subject
* Discussing pros/cons reply to the right subject.

gogol:
As the SAM3X8E allows NRST or NRSTB for reset, make both available.
Right now only NRSTB is available. :-(
If both are available, mark them different on the PCB.
See:

gogol:
Looking to the Electrical Characteristics, the currently used LQFP allows for a max of 130mA on all IOs. The LFBGA allows for 150mA, which might be a better choice, as the digiX allows for much more IO-pins than the DUE.

gogol:
The Due has two crossconnections on digital PIN 4 between PC26 and PA29  and on digital PIN 10 between PC29 and PA28.

Those connections are at least for certain projects counterproductive.  So it might be an advantage, there could be two additional pins for PA28 (digital 77) and PA29 (digital 87) and an solder bridge for both crossconnections, which could be opened, if needed.

gogol:
To allow Pin 52 (PB21) to be used as fourth serial or A12, when using nRF, there should be an jumper, allowing the usage of an alternate PIN for chip-select on the nRF.
Probably PB23 (Pin 102) would be a good choice.
