Color: Orange Yellow Material: PCB V5.0 dual antenna solution (high frequency/low frequency dual gain + dual filtering), can only change the dual antenna solution, the modification is simple (one jumper), and the anti-interference ability is stronger. V5.0 upgrade content: 1. The FPC board is equipped with a high-gain, low-noise high-frequency LNA, and no antenna amplifier is required. 2. Through the integrated interface, the board does not need to solder the feeder. 3. The HF bandpass filter has been redesigned, and a pre-selection filter has been added to effectively shield external interference. 4. The modification is simpler, only one jumper is needed.
