Description: A radio made of ready-made FM radio module can be made by welding the circuits of power amplifier and level indicator. The power amplifier circuit is composed of imported device PAM8406, and the maximum output power is 3W. Two-channel level indication is composed of KA2284.

Specifications:

Power supply voltage: 5.0V-5.5V, current 500MA-2A. Power amplifier+level indicator PCB board size: 9.5CM2.9CM Shell size: 11.9CM6.6CM*6.6CM * 6.6cm. Horn: 4Ω 5w MAX power of power amplifier: 3W Sound channel: two channels FM receiving frequency adjustment range: 87.0MHz-108.0MHz Weight of complete DIY parts: 280g

Precautions: Do not touch the back components of the module when working, so as not to affect the normal work of the module or cause short circuit to burn the module. This module is a radio sensitive device, and the interference from the power supply or nearby may affect the normal work of the module.
