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.

It is used to drive the headphone jack which disconnects the internal speaker once a headphone plug is plugged in.

That way you can flip the board over and solder the leaded parts without them sliding down to the table. I think it’s under KHz. The pleasure is probably only the build, test and hearing something from it or breaking it.
Unfortunately, the instructions are only a single double-sided sheet, so the educational value of the kit is somewhat limited. Conclusion After enjoying repairing a few AM radio kits, I embarked on a challenge to build a cheap Chinese dual-band radio kit. Desoldering braid optional to fix mistakes. Getting to this stage takes about an hour. Just another way engineering solves the day! April 25, at FM radio receiver circuit It looks cdgp datasheet datasheeg to be an FM receiver circuit.
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.

Beginners and Experts Welcome! In my case, I ended up substituting a salvaged from another piece of broken equipment … but this is why having two kits with the intention of making just one might be useful. Maybe one radio station at the most.
Lead the yellow wire to the ANT terminal and tack solder. At this stage, we are ready to make the final connections and assemble the unit. November 24, at 8: One time I even reduced the turns on one of the coils. Proudly powered by WordPress. March 23, at 9: About one to two hours of time to complete the kit. I have required low power isolated DC to DC converter schematic 3.
Superglue is not preferable because it cracks when the case is flexed, but should still work somewhat adequately. Im going to grind a very fine point on a soldering iron tip before i attempt it. Next, solder the speaker wires with both yellow wires going to one SP terminal respectively.
Continuing on, the board is completed with the population of resistors. Another radio that is in tune to verify received stations also recommended, but not absolutely necessary.
CDCB Datasheet PDF ( Pinout ) – Monolithic Power FM radio tuning circuit
Start dxtasheet identifying pin 1 and straightening bent pins. You might get static, or nothing. Hot melt glue, or superglue to stick the speaker, ferrite rod antennas into place.
You do not have the required permissions to view the files attached to this post. Has anyone tried different smaller inductors and can this device “stretch” to about MHz.?

It is used when a minimum of peripheral components of small dimensions and low costs is important. May 20, at 2: Arduinos nano wireless sensor network 3.
In the case of this kit, this specifically includes: You can get a complete scanning FM radio, with headphones, for a buck.
