FM Radio Kit

Description

This DIY kit (HU-017A) is a wireless FM radio receiver with a 4-digit 7-segment display. It operates within the global FM receiving frequency band of 87.0-108.0 MHz, making it suitable for use in any country or region. The kit offers two power supply modes, allowing you to use it both at home and outdoors. This DIY electronic product will help you understand circuits and improve your soldering skills.

Features

  • 87.0-108.0 MHz FM Radio: Built-in RDA5807 FM data processor with a standard FM receiving frequency band. The FM frequency can be adjusted using the F+ and F- buttons.
  • Adjustable Volume: Two volume adjustment methods – button and potentiometer. There are 15 volume levels.
  • Active & Passive Audio Output: The kit has a built-in 0.5 W power amplifier to drive 8 Ω speakers directly. It also outputs audio signals to headsets or loudspeakers with AUX interfaces, allowing personal listening and sharing of FM audio.
  • Configured with a 25 cm dedicated FM antenna and a (red) 4-digit 7-segment display for real-time display of FM radio frequency. The transparent acrylic shell protects the internal circuit board. It supports dual power supply methods – 5 V USB and 2x 1.5 V (AA) batteries.
  • DIY Hand Soldering: The kit comes with various components that need to be installed manually. It helps exercise and improve soldering skills, making it suitable for electronics hobbyists, beginners, and educational purposes.
