DP 666 TEF6686 Radio High Sensitivity Full Band FM AM LW MW SW Shortwave ESP32 RDS 2.8 inch IPS LCD DEEPELEC Please note that we have updated the appearance of the radio since March 2025. The appearance of the shipped products is subject to the following pictures. Main changes: The edge of the shell has changed from a right angle to a rounded corner. Must read before purchase: 1. The DP-666 radio is based on the PE5PVB open source project TEF6686_ESP32 so the DP-666 project source code is open and you can download and compile it yourself. 2. The DP-666 radio is a 2.8-inch IPS display with resistive touch but our firmware does not support touch operation yet. Our firmware is still being improved and there will inevitably be some errors and bugs thank you for your understanding. 3. The DP-666 uses an external antenna a standard SMA male screw female connector and no built-in magnetic rod. The WIFI function is still being improved the Bluetooth function is not yet implemented programmers can study secondary development on their own. 4. We try to make this radio as practical and convenient as possible but it is still a DIY product there will be some flaws and shortcomings perfectionists should buy it with caution thank you for your understanding. DP-666 manual video firmware download: Product Introduction: DP-666 is a high-sensitivity radio based on NXP's high-performance automotive-grade TEF6686 chip which has excellent selectivity and ultra-high sensitivity. This automotive DSP tuner has a wide range of functions and advanced algorithms (CEQ EMS iMS and PACS noise canceller...) SDR(software-defined radio) signal processing especially for improvement of multipath adjacent frequency interference weak signals There are significant advantages in processing and noise cancellation. DP-666 is a radio built on PE5PVB's open source project TEF6686_ESP32. In addition to listening to radio stations the project also supports a wealth of advanced features such as: almost all RDS (Radio Data System) data display automatic/manual station scanning squelch function battery voltage display changeable themes multilingual station presets and more. We redesigned the circuit board with reference to the mature TEF6686 front-end receiving circuit and equipped the DP-666 with a 2.8-inch LCD color screen with resistive touch based on the open source project. While ensuring the portability of the machine it can display rich RDS information (RDS information requires local radio support); a numeric keypad is added to facilitate users to quickly input frequencies; and a large-capacity 5000mAH battery supports longer standby time. In short I hope you will be satisfied with this portable high-sensitivity travel radio! Description Report Item Please note that we have updated the appearance of the radio since March 2025.
