What datasheets have been made available for the roboRIO? I don’t really see anything of actual use here: https://decibel.ni.com/content/docs/DOC-30419, mostly just marketing garbage. I’m guessing it’s fairly similar to the myRIO, but I really don’t want to bank on it. I’m interested in making custom circuits for the MXP expansion, but I don’t know how fast stuff like the SPI bus can rx/tx data. Also, specifics about the ADCs and DACs would be of interest.
I suspect the specifications will be very similar to the myRIO. For the ADC, the roboRIO is 12bit in the range 0-5v, which will give better resolution for most sensors compared to the cRIO (The 9201 is 12 bit in the range of -10 to 10v).
The roboRIO is still in the alpha testing phase. I suspect that NI will release more information later, perhaps during/after Championships.
