DP-666 is a high-sensitivity radio based on for NXP's high-performance automotive-grade TEF6686 chip, which has excellent selectivity and ultra-high sensitivity. This automotive tuner has a wide range of functions and advanced algorithms (CEQ, EMS, 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 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.<br><br>The product appearance and printed words from batch to batch, but not affect the use Color: As Shown Material: plastic<br><br>Package Contents: 1 x Radio 1 x SMA Telescopic Antenna 2 x Donut Antenna 1 x Touch Pen 1 x TYPE-C Cable 1 x Storage Pouch<br><br>Only the above package content, other products are not included.
