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.

Next, solder the speaker wires with both yellow wires going to one SP terminal respectively. Desoldering braid optional to fix mistakes.

After the fact I saw a Russian youtube vid showing the SM chip being slickly soldered with two swipes of a soldering iron after he applied some flux from a pen dispenser. I think it’s under KHz. Use xatasheet slightly different machine screw to secure the antenna to the rear casing. Do not fit them into the casing until they are cool, otherwise you will melt the plastic casing! Note the orientation, unbend the pins, insert and solder away.
So, I rummaged on eBay looking for radio kits, and surprisingly, there were quite enlish few! The schematic as listed is shown above.
Now, the screws need to be sorted and the dials installed. Get good reception aroun Mhz with correct pointer position. February 5, at 7: Let you know how things go. FM radio cdgp datasheet circuit Thank u for the English datasheet and discussion. If I was doing this again, as I did for my second kit, I would populate the resistors before the capacitors mainly because the clearance to get resistors flush on the board dataheet limited once the capacitors are installed. It is used to drive the headphone jack which disconnects the internal speaker once a headphone plug is plugged in.
De-tuning related to the IF and too weak datasheeet signals is suppressed by the mute circuit. I tried to clean up the solders i think i burned a datashest of the pcb board. Can i sandpaper off the green plastic so i cd0988cb use the copper under that to connect to? Maybe one radio station at the most. Having some kit-building experience helps you avoid basic mistakes like this. A Bus Pirate could sure come in handy. Arduinos nano wireless sensor network 3.
The next step is to align dtaasheet AM band. Id like to mount this and hide it well in one of the early empty radio cabinets ive picked up. Bench-top supply with crocodile clips, fd9088cb output to power receiver during tuning recommended, but not absolutely necessary. Yes you can scratch off some of that green solder mask and solder directly to the tracks if you wish.
Uses a chip, which may be an earlier version of the ? Cdgp, while shopping for some electronics, an interesting FM radio kit came to my attention. Think its a cute little radio for the price and works quite well with local stations both fm and am in dxtasheet Winnipeg area. Unfortunately, the instructions are only a single double-sided sheet, so the educational value of the kit is somewhat limited.
From here, we can mount the two copper air-coiled inductors.
Project: Paeansonic CF210SP CD9088+CD7642 AM/FM Radio Kit
Will see if it works as well as yours did. This goes in one direction at the end of the battery compartment and needs to be slid into place in its rails. This entry was posted in AudioElectronicsRadio and tagged cheapdiyebayelectronicsmade-in-chinaprojectradiorf. Then solder each successive pin taking care datasheer to short out adjacent pins.
Sounds like a demented wasp trying to escape a Coca-Cola can. Once roughly in place, you can take the AM-FM mode switch, cd9088cv the plastic and push it through the exterior casing over the switch. That leaves the TDAwhich is a stereo audio amplifier chip to drive speakers and headphones. Preparation We start by first emptying all components into a plastic bowl so they can be sorted through.
The plastic casing is light, slightly weak to flexing and has a tendency to resonate at certain frequencies causing a buzzing sound at higher volumes. Hot melt glue, or superglue to stick the speaker, ferrite rod antennas into place.
Repeat for finding a known station, but instead ce9088cb the left brass screw — the higher one. Im going to grind a very fine point on a soldering iron tip before i attempt it.
Superglue is not preferable because it cracks when the case is flexed, but should still work somewhat adequately. We start by first emptying all components into a plastic bowl so they can be sorted through. March 23, at Start by identifying pin 1 and straightening bent pins. Sound quality is good. The pleasure is probably only the build, test and hearing something from it or breaking it.

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. I suppose I could disable the scan and just use a very ccd9088cb variable cap. Some of the hardware has a habit of shifting in place during soldering.
