Awesome board

The board is great. My only issues have been with the gps antenna and the case. The antenna is being detected in marauder and on bruce but cannot get a fix. It sees an antenna is connected. The other issue is the case. The top broke when I unscrewed it to put in the cyd. Luckily I have a 3d printer and was able to print another.

EDIT: After a quick tear down and a reflash of the firmware, everything is now working.
Customer service is great! After posting the review, Trent reached out and was willing to send out a new board to me. Thank you once again for making a great product which I can now wardrive with!

Marauder Battery and Case Review

Mechanically, everything was great and the CYD fitted just fine.

The battery board has unfinished edges and took some.work to get it to fit into the case.

Very minor issue and overall, very happy.

Thanks for the feedback. We made a change to the case so it's not so tight!
