1. The FPC board is equipped with a high-gain, low-noise high-frequency LNA, and no antenna amplifier is required. 2. Using the onboard interface, the board does not need to solder the feeder. 3. The HF bandpass filter is redesigned, and a pre-selection filter is added to effectively shield external interference. 4. Modification is simpler, only one jumper is required.<br><br>Dual antenna solution: V5.0 (high-frequency/audio-frequency dual amplification + dual filtering), can only change the dual antenna solution, the modification is simple (one jumper), and the anti-interference ability is stronger. Due to different batches, there may be differences in product appearance, color, and printed text, which not affect the use.
