CHANNEL VISION Mini Digital Stereo FM Radio Module 1054501 receiver

Compact FM Receiver Module

The CHANNEL VISION Mini Digital Stereo FM Radio Module 1054501 is a board-level receiver built for DIY audio projects and short-range wireless voice systems. It integrates a 2×3 W stereo amplifier so no external amplification stage is required. The module runs on a DC 3–5 V supply and covers the 76.0–108.0 MHz FM band with DSP and PLL tuning. Makers and hobbyists who need a self-contained FM front-end will find it fits small enclosures.

Thermals Noise Power

Operating from a low-voltage DC source, the board draws minimal current and produces negligible heat during normal listening. The on-board amplifier delivers 500 mW per channel into typical speaker loads without a heatsink. A blue back-light LCD shows frequency and volume status; the backlight can stay on continuously or time out after 20 seconds. No fan or active cooling is involved, so acoustic noise is limited to the audio output itself.

Upgrade Path

This module replaces discrete tuner ICs and separate amplifier boards in portable radios, intercoms, or campus broadcast receivers. The 30-step digital volume control and auto-squelch simplify firmware work compared with analog potentiometer designs. Builders who need DAB decoding, Bluetooth streaming, or multi-channel surround should look elsewhere; the feature set is limited to FM reception and auxiliary line-level input and output.
