The radio is powered from a 5 V USB mains power supply which is not supplied. Included is a power cable from USB-A to standard 5.5 x 2.1 mm power plug. Dominant on the front panel is the display. It shows '==STEREO RADIO==', but that does not make sense, as the radio has only one built-in speaker and is therefore mono. Above the display is a row of ten LEDs. These form a double LED VU-meter, controlled by two KA2284 chips. Below the display, there are two large red push button switches and four small black push buttons. The left red switch turns the radio on or off. Irritating is that the last settings are not stored in the memory. The radio will always start up at the lowest frequency in the FM band that gives an acceptable signal and with the volume set to 8.
EXCELLENT An insulating washer must be placed in one of the holes (indicated in the image), since when the screw is placed it will short-circuit the conductors of the PCB. REGARDS!
Amazing DIY kit, all components are correct with some spares parts. Sound quality is loud and clear. The only downside is that it can't retain the last radio channel once power off.
Long waiting time till product was in stock. It was possible to cancel the order, however. Arrived in airfoil, some buttons had slightly bend legs. Some additional spare parts! assembly was easy!
radiolina perfetta, mi sono divertito molto a montarla e non ho avuto nessun problema, in più guida perfettamente dettagliata! unica pecca è senza protezione lo speaker!che ho provveduto a mettere io
Güzel bir uğraş, tavsiye ederim.👍 Sesi güzel fakat çok açınca ses biraz bozuluyor.
Great DIY design, No schematic diagram but it is easy to assemble, the LCD not showing the right information but I managed to use it without LCD screen, the sound is clear.
Excellent DIY project. Easy to build, and it sounds really good. I use it every day. It comes with spare parts and really good pack. Don't hesitate about it!! It's a must!!
nice FM radio kit wel works perfect
it has decent sound and reception. And was pretty fun to put together, i had plenty of 10K but too few 1K resistors. It’s no problem though, i’m happy to see it working as intended.
