This adapter board is essentially a step-down module with an expanded socket. After 12-16V voltage input, it provides 5V power supply to the FPV analog receiver (students who play time-travel machines all know this) V0.1 superimposed step-down module, in the video signal There is voltage interference V0.2. A wide voltage step-down circuit is directly drawn on the board. The switching frequency of the step-down chip is also relatively high. There is no voltage interference in the video picture. In addition, a 5V power supply switch is added. When the analog receiver is not working, you can use the switch to turn off the 5V power supply (it does not affect the power output of the DC port).
V0.1 had a shell, but V0.2 still has no painting on the shell.
