radio board

Overview

Simple FM radio board:

Equipped with digital automatic gain control circuit, the receiving signal is more stable.

Low power consumption, can be powered by two batteries.

Supports radio station memory function. The next time you turn on the phone, it will automatically restore the radio station and volume when it was last turned off.

Personal test shows that it can be used normally when powered on. It is low cost and easy to carry.
