This is the Lumenier Super Mini 5.8GHz FPV Transmitter + 600TVL Camera + Dipole Antenna. This mini Camera / VTX features 5 bands on the 5GHz band, and it has an easy to read LCD on the back of the unit. The easy to read LCD will tell you which band and channel you are currently on. The 25mW of output power on the VTX gives this unit a much stronger FPV signal, allowing for longer range flights and better penetration through object vs. a standard 25mW.
The unit is ultra-lightweight, so it is easy to place on any aircraft without affecting the COG. Most multi-rotors wouldn’t even notice it was there.
