#The 7th Lichuang Electronic Competition# The card radio is based on RDA5807FP

Overview

1. Introduction to project functions:
A card radio based on RDA5807FP. FM antenna is installed on board (to be verified). Automatically search for FM radio stations. Volume adjustment function. Can be plugged in headphones or external speakers. The size is 5.5X8.5CM, the size of a bus card.
The headphone part has not yet been implemented, but the hardware supports it.
2. The project properties
are almost completely modeled after the circuit of the video "Bilibili", a radio made with domestic chips.

3. Open source agreement

GPL3.0

4.
The main part of the hardware is RDA5807FP. Then connect to 800A op amp. Just look at the schematic diagram.

5. Competition LOGO verification

6. Demonstrate your project and record it as a video and upload it
