How to Solder and Build an FM Radio | RADIOSOL RDA5807 Kit Step-by-Step

Build your own FM radio from individual electronic components with this step-by-step RADIOSOL assembly tutorial. In this hands-on electronics project, you will assemble the complete radio circuit board, solder the electronic components, install the digital display, connect the speaker and battery terminals, assemble the enclosure, and test the finished radio. The RADIOSOL kit uses an RDA5807 FM radio module, TDA2822 audio amplifier, STC8G controller, 4-digit digital display, resistors, capacitors, switches, antenna, speaker, and other components to create a functional FM radio with automatic station searching and adjustable volume. This project is ideal for electronics students, STEM activities, soldering practice, hobbyists, classrooms, and anyone interested in learning how electronic components are assembled into a working device. In this video, you will learn: • How to identify and install electronic components on a PCB • How to solder surface-mounted and through-hole components • How to identify resistor values using color bands • How to identify electrolytic capacitor polarity • How to correctly orient IC sockets and integrated circuits • How to install an LED with the correct polarity • How to install the RDA5807 FM radio module • How to install a 4-digit digital display • How to connect battery terminals and the speaker • How to assemble the radio enclosure • How to test and troubleshoot solder connections • How to power the radio using batteries or USB CHAPTERS 0:00 Introduction 0:27 AMS1117 Voltage Regulator 0:48 RDA5807 FM Radio Module 1:14 USB Power Socket 1:31 10K Resistor 1:52 1K Resistors 2:18 510 Ohm Resistors 2:41 1 µF Electrolytic Capacitor 3:05 8-Pin IC Socket 3:19 16-Pin IC Socket 3:29 LED Installation 3:48 Toggle Switch 3:59 Audio Output Socket 4:12 104 Ceramic Capacitors 4:32 200K Potentiometer 4:43 100 µF Electrolytic Capacitors 5:13 4-Digit Digital Display 5:33 Tact Switches 5:44 Antenna Installation 5:53 TDA2822 and STC8G Chips 6:40 Battery Contacts and Wiring 7:34 Speaker and PCB Installation 7:58 Initial Power Test 8:11 Volume Adjustment and Case Assembly 8:27 Battery Compartment and Buttons 8:48 Radio Test and Troubleshooting 9:11 Additional Information RADIOSOL FM Radio Soldering Kit Build the complete project with the RADIOSOL kit: https://shop.miniscience.com/RADIOSOL POWER INFORMATION The radio can be powered using three AAA batteries or a USB power source. Do not use USB power and batteries at the same time. Select only one power source. TROUBLESHOOTING If the radio does not operate correctly, first try a new set of batteries or a different USB power source. If the problem continues, carefully inspect all solder joints. One or more solder connections may not be making proper electrical contact. When the radio is assembled and soldered correctly, it should power on and automatically begin searching for FM stations. SAFETY Soldering irons become extremely hot and can cause burns. Work in a well-ventilated area and follow proper soldering safety procedures. Adult supervision is recommended for younger students and beginners.
