Dual antenna solution: V5.0 (high-frequency or audio-frequency dual amplification and 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. Using the onboard IPEX 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.
