Stereo AM radio kit / DIY CF210SP electronic production suite For Arduino AM / FM

Introduction to JC210SP Radio Kit 

Overview 

The JC210SP Radio Kit is an AM/FM dual-band radio featuring a novel and unique appearance. It balances practicality and ease of assembly, making it suitable for radio enthusiasts, electronic DIY beginners, and students learning circuit principles—whether for daily radio listening or hands-on electronic practice. 

Core Performance & Circuit Configuration 

1. FM Band (76-108MHz) 

- Core Chip: Adopts the CD9088 chip, with all components using surface-mount technology (SMT) packaging—small size, stable performance, and low signal interference. 

- Receiving Range: Covers 76-108MHz, enabling reception of not only standard FM radio broadcasts but also campus radio signals and audio signals from some TV stations (meets diverse listening needs). 

2. AM Band (525-1605KHz) 

- Core Circuit: Uses the TA7642 direct-amplification integrated circuit—circuit structure is simple, reducing assembly difficulty and ensuring a high assembly success rate. 

- Key Advantages: Good signal selectivity, enabling clear reception of AM radio stations without obvious cross-station interference. 

3. Power Amplifier & Power Supply 

- Power Amplifier Circuit: Equipped with the TDA2822 chip, which delivers loud sound output and excellent audio quality—no distortion even at high volume, enhancing the listening experience. 

- Power Supply: Powered by a 3V DC power supply, compatible with 2 AA batteries (size 5 batteries)—easy to obtain power sources, convenient for portable use.
