CDCB Datasheet – Monolithic electric tuning FM radio IC, CDCB datasheet, CDCB pdf, CDCB pinout, equivalent, data. The only English you will find is in the listing description, which isn’t for FM reception, with the only datasheet I could find being in Chinese. The IC type is YD I tracked down a datasheet and put it on my site. Looks like a good project. Use a fine-tipped iron and keep the tip clean.

Of interest is that the reception mode switch actually switches the audio path to the amplifier. The capacitor markings can be hard to read, but are mostly three digit indicating the first two significant figures and number of zeros in pF.

Then, with a molten blob of solder on your iron tip, you use it like a brush and sweep the molten blob of solder down one row of pins. In doing PCB for high frequency circuit, please make sure that you place components datashfet close as possible to cdgp datasheet the lenght of the tracks as short as possible because two parallel tracks may form capacitance and as you know cdgp datasheet capacitor is frequency dependent.

February cd908cb, at 7: Then secure this with the other identical machine screw. Trouble was already spotted c9088cb a loose screw was seen rattling inside the bubble wrap — the components have broken loose and the only thing preventing them from going everywhere was a thin and somewhat torn bubble wrap.

If you have used enough flux, there will be no bridges of solder between the pins – use a loupe or a powerful lens to confirm. There is also a method whereby the tracks can be designed and used as antenna.

May 19, at 8: The values can either be read or checked with a meter. Try not to bend the leads too severely, as datashwet the other protective coating can have detrimental effects on capacitor stability or performance.


May 20, at 2: Go to the help icon in the window of the software you are using and you will see how to work with the PCB software. The next step was to mount the hardware — the headphone jack, the variable capacitor, the volume switch and the band switch. Well, it took 2 months for my kit to arrive, the PCB was bowed, and some of the caps were illegible, but it worked on the first try. Note the temptation to use hot-air reflow techniques.

For this kit, I preferred to do things the opposite way. June englixh, at Adding a load datasueet the auxiliary winding of the TNY circuit 2. Here’s a top view, from the datasheet: Align the switch and use one of the two identical machine screws to fasten. I found the top of the FM band hard to reach, but not impossible with a combination of spreading the coils and adjusting the offset trim on the variable capacitor itself. FM radio receiver circuit PCB cdgp datasheet differ slightly from cdgp datasheet.

Because there were more capacitors, I decided to tackle them first. It is neglish very small surface mount chip. The pleasure is probably only the build, test and hearing something from it or breaking it. The paper substrate also likes to discolour with such heating and smoke. Mechanical Parameters of RC servo 4. Then solder each successive pin taking care not to short out adjacent pins.

In the case of this kit, this specifically includes:. Clean up all the excess flux when you’re done. But at least they did provide the jack. My board looks like this — ready for the population of resistors.

March 23, at I cd9088cn have used the wrong screw for the antenna as it became loose and I ended up replacing it with a self tap of slightly larger size. Next thing was to solder a pair of yellow wires to the positive and negative of the speaker. The AM rod antenna connections can be made by looping out the enamelled wire over the top of the PCB is best and tack soldering the ends to AM terminals.


A Bus Pirate could sure come in handy. Just another way engineering solves the day! The AM reception is being achieved with the CD This entry was posted in AudioElectronicsRadio and tagged cheapdiyebayelectronicsmade-in-chinaprojectradiorf. Maybe one radio station at the most. You do not have the required permissions to view the files attached to this post.

It is used when a minimum of peripheral components of small dimensions englksh low costs is important. Finally figured out K1 and K2 are momentary pushbuttons. After all, it shows just how numbers and drawings can easily transcend the language barrier.

In fact, the case even has a few curves to make it look just that little bit more stylish. Before starting the assembly I recommend you first check that no parts are missing. As mentioned, the instructions were all in Chinese.

Then, do the same with the other row of pins after you’ve allowed the chip to cool off datashfet little. Turn the tuning dial to a known station location, wnglish if you have a second radio, have it playing the same station.

I actually tried this on my second kit and it was a disaster. In the case of this kit, this specifically includes: If you are into building radios, then this. Turn the tuning dial to the lowest frequency longest indicator length and carefully thread the tip of the tongue through the slot while shifting the PCB into place.

Now, the screws need to be sorted and the dials installed.
