The Micro Minim is the next step in micro OSD's. It has all the same features as its larger counterpart (except for the DC to DC converter) but in a tiny 15 x 15mm size. The Micro Minim OSD was engineered to bring users a very powerful OSD that will fit on very small models, perfect for the FPV 250 racing quads that are becoming extremely popular.
You can choose firmware that is MAVlink compatible for ArduCopter or MultiWii Serial for MultiWii and Baseflight/Clearflight control boardsand has MWOSD suport . You can also connect 2 batteries up to 4S so that you can display main flight battery voltage, the 2nd port will allow your FPV battery voltage to be displayed as well.
