We’ve had a bear of a time with the RoboRio 2s. We’ve had no issues with RoboRio 1s (this year or in the past).
Maybe this is just the 2 we ordered, but I’m not liking the MicroSD cards much right now. The MicroSD card slot doesn’t seem very robust and doesn’t behave like other devices that have MicroSD cards. Other devices (RPi, Card Readers, etc.) have a “springiness” and you have to be careful when ejecting the card. With our RoboRio2s, we’ve had:
-
Cards fall out of the RoboRio when it is turned over
-
Cards get stuck in the RoboRio MicroSD card slot (get a tweezers to pull them out)
-
Many different errors when imaging the RoboRio (imaged one successfully during beta, but with the new image, we’ve been having issues re-imaging it)
At this point, I don’t know if we’ll run a RoboRio 1 or a RoboRio 2 at competitions the whole MicroSD card issue and the failure modes associated with it are making us uneasy right now.
