Due to different batches, there may be differences in product appearance, color, and printed text, which will not affect the use.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.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.Colour:Orange-YellowMaterial:PCBPackage Contents:1 * Module2 * Donut Antenna(with adapter)1 * USB Programming CableOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
