I had a crash that pushed the IMU/controller/gyro box right through the center of the main board, so I started looking for a replacement board. I learned that there are original and updated versions of the board, part 33 for 2312 motors, part 96 for 2312A motors. I have 2312 motors that still work, so I thought I'd just get the original board rather than having to get all new motors as well. I found that DJI's site has "not available in your region" for part 33, so I found one at an authorized DJI dealer. It came in a DJI box with a Part 33 label, and it was sealed. It also came with an instruction card on distinguishing between the original and updated versions of the board. Here's the problem, though.. the board in the box doesn't match either. The card shows that original should have a label with first line ending in "A" and updated ending in "B". The board in the box ends in "C" and looks more like a "B" board. For reference, here is an "A" board, part 33: and a "B" board, part 96: Could this "C" board perhaps be compatible with 2312 motors, or is this just a mistake? Thought I'd check here to see if anyone knows about this, wasn't able to find anything in search. Thanks!
