The Icstation 108.0MHz Wireless FM Radio Receiver is a DIY kit designed for training welding skills and electronic project design. It features an HD LCD display, automatic station search, and a built-in 5W power amplifier. The device supports a frequency range of 76.0MHz-108.0MHz and includes a power-saving mode.

Operating instructions
Basic Controls:
- Power Switch: Turns the device ON/OFF.
- AUTO Button: Long press to automatically search and store FM stations. Short press to toggle the mute function.
- P+/P- Buttons: Switch between saved FM stations.
- SP+/SP- Buttons: Adjust volume from V00 to V30.
Advanced Settings:
- Campus Broadcasting Band: Keep SP+ and SP- pressed before powering on. Display C1 enables the band; C0 disables it.
- Backlight Mode: Keep P+ and P- pressed before powering on. Display B1 keeps the backlight ON; B0 turns it off after 20 seconds (power saving mode).
Charging: The device uses a red LED indicator for charging and a blue LED for fully charged. Note that the FM radio cannot be played while charging.
Assembly and installation
Installation Tips:





- Prepare necessary tools: Soldering iron (<50W), rosin core solder, wire cutters, wire strippers, and a screwdriver.
- Do not touch components with the soldering iron for more than 1 second to avoid damage.
- Pay attention to component polarity and installation direction.
- Wear anti-static protection during assembly.
Assembly Steps: The assembly involves soldering SMD components (LM4863), resistors, capacitors, and sockets onto the PCB, followed by connecting the speaker and antenna. Finally, the acrylic shell is assembled around the PCB using copper pillars and screws.
Component list
The kit includes essential parts such as the LM4863 Power Amplifier, FM Receiver Module, 18650 Lithium Battery, 5W Speaker, various resistors, capacitors, buttons, and an acrylic housing set. Users should verify all components against the provided list before starting assembly.
