This document describes the RDA5807 FM 87-108MHz Radio Receiver LCD1602 DIY Kit, a self-assembly kit designed for enthusiasts to build their own FM radio receiver. The kit features an RGB spectrum indicator that flashes automatically and a blue LCD1602 display screen for clear frequency indication.
The RDA5807 FM Radio Receiver DIY Kit allows users to construct a functional FM radio. It incorporates a built-in volume adjustment, an RGB spectrum indicator for visual feedback, and a 5W power amplifier for audio output. The device supports a receiver frequency range of 87.0MHz to 108.0MHz, enabling reception of standard FM radio stations. The LCD1602 display screen provides a clear visual representation of the currently tuned frequency.
The kit's operation is straightforward:
The RDA5807 FM 87-108MHz Radio Receiver LCD1602 DIY Kit boasts several key technical parameters:
The kit includes a comprehensive list of components necessary for assembly, such as various metal film resistors (10ohm, 100ohm, 6.8Kohm, 1Kohm, 10Kohm), the RDA5807 FM Receiver (SMD), a crystal oscillator (11.0592MHz), IC sockets (DIP-8, DIP-40), ceramic capacitors (22pF), monolithic capacitors (0.1uF 104), KA2284 LED drivers (ZIP-9), RGB LEDs (5mm), DuPont female and male sockets (16Pin), electrolytic capacitors (4.7uF, 100uF), a DC-005 power socket (5.52.5mm), self-locking buttons (5.85.8mm) with red caps, black buttons (6620mm), an LM386N IC (DIP-8), an STC89C52RC IC (DIP-40), an LCD1602 display screen (blue), a 75ohm antenna (25cm), a 4ohm 5W speaker (22mm), red/black speaker wire (20cm), and a USB-DC005 power wire (100cm). Mechanical components include an acrylic board, M310mm copper pillars, M310mm, M38mm, and M36mm screws, and nuts. The PCB itself measures 82641.6mm.
The RDA5807 FM Radio Receiver is designed for ease of use once assembled. Its compact size (907055mm) makes it portable. The blue LCD1602 display ensures that the current frequency is always visible. The RGB spectrum indicator adds a dynamic visual element to the listening experience, flashing automatically to enhance user engagement. The built-in 5W power amplifier provides sufficient audio output for personal listening.
As a wireless module, it is important to note that the device should not be used in environments with significant signal interference to ensure optimal reception quality.
The kit is primarily a DIY assembly project, and maintenance largely revolves around proper installation and handling of components.
The installation process is detailed step-by-step, covering the placement and soldering of each component, from the RDA5807 FM Receiver SMD to the final assembly of the acrylic casing and speaker. This detailed guidance aims to minimize errors and ensure a successful build.
