What about integrating a max7456 so the osd can be combined. Perhaps that way one wouldnt need to add extra cables, the "core" vrbrain could run minimosd-extra or whatever as a different task which takes care of updating the osd.

Nice job Roberto! The board looks good, everything is in it's right place and updating the firmware from the mission planner is great!

This is great accomplishment by FOXTEAM and APM community.

Nicely, nicely...
Looking forward to a very light and small package in my mail box with poste italiane on it.

at the moment we don't intend to put an osd on micro brain , we implemented a osd inside our telemetry link with some interesting new features.

@Teddy ,

thank to join us in pre order ...   A lot of guys place a pre order in these days i'm very happy that VRBrain micro like a lot :)

Sure the integration in Mission planner is a good result for integration of Virtualrobotix in APM community :)

Thanks Jiro and Giovanni :)

Hey Roberto, excellent news. micro brain seems to be a really nice FC. I have a couple of questions:

  • input/output cables included?
  • PPM sum supported or "just" s-bus?
  • on the backside there are unsoldered pads, one looks like it might carry a sim card slot, any details on this?



Comment by Roberto Navoni on June 3, 2014 at 1:52pm

Hi Simon,

yes input / output cable is included.

Yes support sbus and ppmsum,too

on the backside there is sd card for data logging supported by Nuttx OS .

Good to see the progress of your team Roberto. Ordered one a few weeks ago and looking forward to it. ;)
