Description

V4 Upgrade Details:

1. Added shielding cover to the Si4732 receiver section to suppress electromagnetic interference; added ESD protection at the antenna input for chip safety.

2. Hi-Z circuit moved to the front end of the antenna path, powered by more stable VCC_RADIO, to preserve signal resonance and reduce noise.

3. New feature: Wired headphones can now be used as an FM antenna (Note: Headphones are not included in the package. Buyers need to prepare their own. Best results are achieved in strong FM signal environments with longer headphone cables).

4. Left and right audio channels have been swapped; amplifier and speaker parameters have been readjusted to improve sound quality.

5. Upgraded to more durable and higher-quality components: sturdier retractable antenna and non-slip knob caps for better handling.

1. Equipped with ESP32-S3 main control + SI4732 DSP, supports ALL Band broadcasting, LSB, USB, AM, and FM modes, with AGC/ATT function.

2. Features a 1.9-inch IPS high-definition color screen with adjustable backlight brightness and battery level display.

3. Built-in 1W power cavity speaker for loud and clear sound quality.

4. Supports firmware upgrades; pre-installed firmware version is at least VER.2.3.1 (Regular updates are recommended for optimal performance).

5. Built-in headphone amplifier circuit for powerful audio output when using headphones.

6. Integrated Hi-Z circuit to enhance weak signal resolution.

7. Uses genuine ESP32 modules (ESP32-S3-WROOM-1-N16R8), ensuring higher reliability compared to counterfeit modules.

Please note when purchasing:

1. If the numerically controlled metal casing version is chosen, the numerically controlled aluminum alloy material has a certain shielding effect on wireless electromagnetic signals. While improving the performance of receiving interference, it will also lead to a weakening of the connection strength of the wifi signal. Please pay attention to this point before purchasing.


2. Headphones are not included in the shipping list. The headphones in the picture are only used for demonstrating the FM antenna function. Please bring your own headphones!
