Color: Orange Yellow Material: PCB 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 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 built-in IPEX interface, the board does not need to solder the power conductor. 3. The HF band-pass filter is redesigned, and a pre-selection filter is added to effectively protect against external interference. 4. Modification is simpler, only one jumper is required. Due to different batches, there may be differences in product appearance, color, and printed text, which does not affect the use.
