is it possible to get the Gerber files for this breakout board?

Hi – I bought an FM transmitter from SparkFun (product URL at bottom). In fact, I bought ~8 of these so far. Ive been unable to affix leads to each of the contacts. Any help is appreciated before I buy 80x more!

Do I even need to solder leads to all 8+7 (15) contacts!?

Please consider changing the name of this item so that it is more clear that this is a TRANSMITTER and not another receiver.

I've realized a small ATtiny85 development, you can find here the electronic scheme: http://www.paratte.ch/Jean-Marc/tiny85_variometer/tiny85_variometer_develop_1.pdf
It's a variometer/altimeter built with a BMP085 Breakout and audio bips are sent via a NS73M Breakout.
All ICs/Breakouts are linked via I2C. Note that the BMP085 Breakout includes 4k7 pull-up on SCL & SDA lines.
This circuit works well but with 2 observations:
1/ SCL line must have a fast rise-up time else the NS73M can't initialize. I've observed that my development ISP cable & custom electronics are too capacitive. I've added another 1k5 pull-up on SCL line to solve the problem.
2/ Because it's a variometer, the BMP085 is permanently asked via I2C bus. And we heard I2C pulses on FM as a light white sound. I think I need to disconnect the NS73M from the I2C bus after initialization to clear the sound.

It would be great to have a board based on the Si4713 which provides RDS encoding as well. That is what i am looking for.

I am having a strange problem with the NS73M board: I run it with an Arduino via I2C. The I2C lines are pulled up to 3.3V via 10k resistors. Everything works great. I can adjust the transmit frequency, adjust the output power etc...However, when I connect an audio source (~100mV) to one of the inputs the I2C communication dies. Sometimes it keeps working for a few commands, usually it is dead right away. When I connect the audio source the audio is transmitted, i.e. this works. But somehow it is influencing the I2C setup. I tried several audio sources including a AD9833 waveform generator chip...always the same. After I2C dies, I have to power down everything for a few minutes. Then I can communicate again...I tried this with two different NS73 boards, i.e. the boards are probably not the problem...Any input will be appreciated! Thanks!

It would be very useful to have a Quickstart Guide for this product, similar to the one you have for the Si4703 Tuner.

For anyone considering this part: It truly is a great FM transmitter! I've made something similar to http://www.km5z.us/FM-Stereo-Broadcaster.php However I notice that some noise of the electronics is picked up in the signal. As I'm not really an expert in this, can anyone give me advise on how I can make sure this doesn't happen? Probably a capacitor somewhere (where??) or shielding of the audio lines? Many thanks!

Anyone interested in the part should try running a half-wave dipole. Monopole is going to be lousy with only a tiny ground plane.

It's an analog transmitter... to use with an embedded digital device it must have a DAC, or at least a tone generator of some kind. The simplest thing you could do on Arduino or similar board is to implement morse code that can be received on FM radio. Use a square wave near 500 Hz. That's a pretty lame application, but analog systems tend to require more analog or relatively sophisticated digital. It would be easier to hook the damn thing directly to a turntable, for example, than it is to get a cool app out of an Arduino.

I had one of these running for about 6 months in a circuit that I prototyped so I could have music in my car. It wasn't the best, but it was good enough for my uses. After about 6 months or so, the transmitter mysteriously died. Everything seems to be operational with everything else, but it just doesn't broadcast anymore.

Any ideas of what could have went wrong? I had it turned on going down the road and suddenly it just turned off. When I got where I was going, I checked it and there was nothing loose or that could've shorted it in anyway. I had a small capacitor over the power lines as well to try to absorb noise. The power basically went USB car adapter -> Arduino -> FM transmitter.

I tried to use this board with Breakout Board for ADMP401 MEMS Microphone (http://www.sparkfun.com/products/9868) to create mini radio station but I cannot get a FM radio to receive any audio out of it. Please help!

Can the transmission span be changed to the woldwide FM band
76 - 108 Mhz by using a different crystal? Or maybe lowered a
bit below 88 Mhz. Any vendors for such a crystal? Thanks!

Does anyone know how/if this would work with an Arduino? If so, does anyone have example code?

hi
previous comment link is change to link.
One more info is that Niigata create a new chip that is NS741 and that support RDS. Unfortunatly that company's website is not so usefull to retrieve needed info.
One more... I'm developing board to directly interface NS73 with ATtiny45 that use VUSB library to directly connect to PC...more info should be provided in next week.

Just got this it is a great little board, easy to solder headers to, and small. But the board is red not green.

As a newbie, I hope someone can help me with my possibly "dumb" question. wht exactly do I need to do to get this one working? aside from an antenna that is? for instance the digital tuning part? how exactly? <br />
thanks!
