FM Radio Receiver DIY - 87/108 MHz (Part-1 PCB Assembly)

This is an 87.0MHz-108.0MHz Wireless FM Radio Receiver DIY KIT. It has a built-in 4-digit Red Digital display which can clearly display the receiving frequency.

Feature:
- Automatic memory function after power off
- Support 87Hz-108MHz receiver frequency
- Built-in 5W power amplifier (LM386 IC)
- Output power: 5W*
- Power saving mode (Display off after 5 seconds)
- Product Name: FM Radio Receiver DIY Kit
- Work Voltage: DC 4.5V~5.5V
- Output impedance: 8ohm
- Output channel: Mono
- Receiver Frequency: 87.0MHz~108.0MHz
- Frequency accuracy: 0.1MHz
- Equivalent noise: 30dB
- Work Temperature: -40℃~85℃
- Work Humidity: 5%~95%RH
- Size: 83x69x53mm

*The amplifier of this radio is an LM386, so I think the real power output is 1 Watt

I built this and it worked for a minute now it lights up nothing else can you help me pley

Sadly my chip was broken, currently waiting on a new replacement that is coming in tomorrow. Hopefully the second time I can finally get my radio up and running. Also I really wish I saw your video before I put it together, I would of saved somewhat of a small headache when trying to figure out the best way to put it together.

It turns on and makes noises when I move up and down but no radio coming through. The screen also goes blank after a few seconds! Any idea why?

[arnoldarlante]

What will be the alternative power source because I don't have an exact 5v.

Any idea where I could find the coding for this transmitter?

where is the code ? for microcontroller
