ATS125 High Sensitivity Multifunctional Bluetooth FM Radio TEF6686 Vehicle DSP Tuner with 2.4-inch LCD

ATS125 High Sensitivity Multifunctional Bluetooth FM Radio TEF6686 Vehicle DSP Tuner with 2.4-inch LCD

Description:
- The ATS125 is the latest high-performance, high-sensitivity, and multifunctional Bluetooth version radio produced after the continuation of the ATS20/ATS25/ATS100/ATS120/ATS200 series radios.
- It is an open-source project based on PE5PVB, optimized and combined with the high-performance Bluetooth chip from Jerry, and integrated with the NXP high-performance automotive grade TEF6686 chip for high sensitivity and high fidelity Bluetooth function radio. It has excellent selectivity and ultra-high sensitivity.
- This car DSP tuner has a wide range of functions and advanced algorithms (CEQ, EMS, iMS, PACS, noise eliminator...), software defined radio signal processing, and significant advantages in multi-channel improvement, adjacent frequency interference, weak signal processing, and noise cancellation.
- The radio built on TEF6668_SSP32 not only supports listening to radio stations, but also offers rich advanced features such as almost all RDS (Radio Data System) data display, automatic/manual radio scanning, mute function, battery voltage display, variable themes, multiple languages, radio presets, and more.
- We have redesigned the circuit board based on the mature TEF6686 locomotive front-end receiving circuit, and selected a 2.4-inch LCD color screen with resistive touch on the basis of an open-source project; While ensuring the portability of the machine, it can display rich RDS information (RDS information requires support from local radio stations); Added a numeric keypad for users to quickly input frequencies; Equipped with a large capacity battery of 2500mAH, it supports longer usage time.
- In short, this portable high-sensitivity travel Bluetooth version radio hopes to meet your satisfaction! Due to the continuous optimization and updates of the firmware by both domestic and foreign enthusiasts, new features will be introduced, and the manual may have different functional differences. We apologize for any inconvenience caused.
