Welcome to the store! 1. The FPC board is equipped with a high-gain, low-noise high-frequency LNA, and no antenna amplifier is required. 2. Using the built-in IPEX interface, the board does not need to solder the feeder. 3. The HF band-pass filter has been redesigned, and a pre-selection filter has been added to effectively protect against external interference. 4. The modification is simpler, only one jumper is required. Dual Antenna Solution: V5.0 (high-frequency/audio-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. Due to different batches, there may be differences in the product's appearance, color, and printed text, which do not affect the use.
