ESP32 TEF6686 Radio PCB Enclosure | Built-in 5000mAH Battery | World Band Receiver FM/AM SW/MW with RDS

The Esp32 TEF6686 radio is a standalone radio device that uses the ESP32 microcontroller and the NXP TEF6686 DSP tuner chip to deliver high-quality sound and performance. The ESP32 TEF6686 is a standalone radio with a built-in battery for high-quality sound and performance. It features a 3.2-inch large screen that displays the frequency, voltage, and other information. It also has a built-in stereo speaker that produces clear and loud sound with minimal distortion. The Esp32 TEF6686 radio has a strong anti-interference ability that ensures stable reception of medium wave, short wave, and FM signals. It also has a built-in LNA (low noise amplifier) that can be switched on or off by a slide switch to improve the signal sensitivity and quality. The enclosure is made of the double-sided PCB with full copper design, which enhances the durability and heat dissipation of the device. The PCB enclosure is sturdy and durable, protecting the device from damage. The Esp32 TEF6686 radio has a voltage display that shows the battery level and reminds you to charge it when it is below 3.3V. The charging voltage is 5V, which is compatible with most USB chargers. The Esp32 TEF6686 radio comes with a telescopic antenna with SMA port, which can be easily attached and detached to your radio. The device has a built-in 5000mAh lithium battery that provides long-lasting power for hours of listening. The Esp32 TEF6686 radio has a compact and portable size of 115 x 106 x 20mm or 4.5 x 4.2 x 0.8 inches and a light weight of 334g/0.7lb, making it easy to carry around and enjoy your favorite radio stations anywhere.
