CF210SP DIY Radio Electronic Kit, FM AM Radio Receiver Circuit Board Soldering Training Module for School Teaching Practice

、The DIY Radio Electronic Kit (210SP / CF210SP) is a classic, dual‑band AM/FM radio receiver designed specifically for school teaching, soldering practice, and electronics training. Ideal for students, hobbyists, and beginners, this unassembled kit provides a complete hands‑on experience from component identification to building a fully functional radio. This kit includes a high‑quality PCB, all necessary electronic components: resistors, capacitors, inductors, CD9088 (FM) and TA7642 (AM) integrated circuits, TDA2822 audio amplifier, speaker, telescopic antenna, tuning knob, volume control, and a durable plastic enclosure. The FM band covers 76‑108MHz (standard broadcast, campus radio, and TV audio), while the AM band receives 525‑1605kHz. The circuit design is straightforward, ensuring a high assembly success rate even for novice users. Assembly takes 1–2 hours and teaches core skills: reading schematics, proper soldering techniques (through‑hole and basic SMD), component polarity, and circuit testing. Step‑by‑step instructions guide users from soldering small resistors and capacitors to mounting the ICs, speaker, and antenna. The kit operates on 3V (2×AA batteries), making it safe and portable for classroom or home use.
