TEA5767 FM Receiver Module

The TEA5767 is a low-power FM radio receiver IC that communicates with Arduino via the I2C bus. It receives FM broadcasts in the 76-108 MHz range, covering all Indian FM stations. With just a TEA5767 module, an Arduino, and a speaker, you can build a fully functional FM radio with digital tuning, station scanning, and frequency display — all for under ₹400 in components.

Unlike the old-fashioned variable capacitor tuning approach, the TEA5767 uses PLL (Phase-Locked Loop) synthesis for precise digital frequency control. You send the desired frequency via I2C, and the IC tunes to it with 50kHz precision. This makes features like preset stations, auto-scan, and favourite lists straightforward to implement in Arduino code.

The TEA5767 module is compact (approximately 12mm x 12mm), operates on 3.3V, and includes an onboard antenna connection point. For Indian FM reception in cities, the included wire antenna provides adequate reception. In rural areas or buildings with thick walls, an external antenna improves signal quality significantly.

Specifications and Features

The specifications and features aspect of a fm radio module project requires careful attention to component selection and circuit design. For Indian makers, the key is balancing cost with performance — using affordable components from Zbotic.in while maintaining audio quality that makes the project worthwhile.

When working with audio circuits, proper grounding and signal routing are critical. Keep audio signal paths short, use shielded cable where possible, and separate power supply wiring from audio wiring. These practices eliminate noise and interference that can plague audio projects, especially in the electrically noisy environments common in Indian homes and workshops with multiple appliances on the same circuit.
