Just what I needed to convert my CD into Bluetooth

For VWCDPIC Audio Interface Adapter

The seller/creator is of the highest integrity, had a slight mix-up on male vs female mini but it was actually good for me. Still, he insisted on refunding. Wow. I really wish he would keep the money! It's worth more! But I got the version (for my US 2002 Eurovan) without preamp. Now I realize that I prefer with preamp, so will buy another.

Great device, great seller.

Fine design of a 328PB UNO configurable as PB or P(A)

For unoPB

The ATmega328PB has some useful additions to the 328P, like a second Rx/Tx, and this board lets you use them. There are options for 328P compatibility, alternate crystals, alternate USB connectors, and an on-board, external, or no USB-TTL.
The board has additional connections for all the UNO pins/headers. I've used Tomas Kovacik's NanoPB and I'm sure this board will be just as good.

Solved my volume problem completely

For Volume fix for audi concert1/chorus1

I got my order in a very short amount of time and soldered it together and it works beautifully.

Very great communication with the seller.
I would 100% recommend.

Great board,

For BM20/BM62 breadboard adapter

Great board (BM20) exposes all pins. Adequately pre-soldered compones as per order. Fair pricing btw!

Ordered twice, quick shipping with adequate protection for transport (from and to EU).

Would definitely order more (different) boards from this seller if they fit my hobby requirements!

Nice module that works with my Skoda Symphony radio.

For VWCDPIC Audio Interface Adapter

Nice module, I did had some issues because the PIC wasn't programmed with the right code. But the seller (Thomas) corrected it right-a-way. It works as expected on my Skoda Symphony radio. nice signal with no distribution at all. Documentation a bit low, but you can build it with some googling and very close look on the pictures.

Highly Recommended

For VWCDPIC Audio Interface Adapter

Audi A6 C5 2000/1 with Symphony 1
Ordered THT kit, works perfectly.
Just add 2 to your software coding to add CDC.
For example, from 00205 to 00207.

Far better than poor quality bluetooth connection, and keeps use of front cd player.

A Better Nano

For NanoPB

The NanoPB is based on the 328PB -- a more capable 328P. There are 2 extra pins on the board, so it generally won't be a drop-in replacement for a regular Nano. As Tomas says, if you like to solder or want learn to solder SMT, then buy the kit. I bought one and had difficulty soldering the CP2102 IC -- it's a QFN package and requires a practiced hand to solder. I would recommend this board and I would recommend buying it assembled.

The board design is good and the provided parts sheet made for quick assembly. As expected the board performed well. A design I have using 2 serial ports can now be made with both as hardware ports.

Thx Donald!

regarding cp2102 I was thinking about option with this chip soldered, but I just do not have time to make it, also when I solder this chip I can solder all components, cose it take 2/3 of time as you say. But you chalange your self, made it and now you can say you can do it in your projects!

I will fix info about drop in replacement, I was talking about breadboard, this is how I use my NANOs.

thx again for input.

Success on Audi TT CDC

For VWCDPIC Audio Interface Adapter

Product works perfectly, and I did not require a pre-amp to run 3.5mm audio.
I cut the pigtail off of a 6 disc changer from a junkyard, and soldered the 3.5mm and adapter directly to the pigtail. This allowed me to plug directly into the 13DIN connection behind the drivers seat, without removing the radio or modifying any wiring in the car.
It took about a month to clear customs to the US.
Thanks Thomas!

Excellent material, quick shipping, nice seller.

For adapter for BK8000L/BK3254 (breadboard friendly)

I didn't had the time to solder yet, but the pcb look real fine.
Great idea to make the adapter breadboard friendly.
Thank you very much!

Perfect solution! Works well!

For VWCDPIC Audio Interface Adapter

Works perfect! Recommended for use or oder with a preamp! Easy to built in. Tiny enough for hide. I use the original box next to the radio to hide the cable.

Perfect stuff, good price, nice seller!

For VWCDPIC Audio Interface Adapter

The item is good quality, the jack cable is a little bit "chinese" (thin cable), but the adapter is work great, the documentation is perfect, the seller communication very fast (and valuable), so I love it! Thanks everything!

Edit: The cable is not problem, works great, just not too nice. :P The quality / price is perfect!

Response from Tomas Kovacik | Sept. 26, 2017
Thx! to audio cable it's brought in EU but as all I'm sure is from china as almost everything. It's actually 3m jack to jack cable split in half, cose if I fabricate this cables used jack will be ugly and bulky, which is not nice at car environment .... so this is compromise to have nice cable

Great product for the price

For VWCDPIC Audio Interface Adapter

Great product, I appreciate excellent communication and also the fact that you can customize - choose between having or not having amplifier or what type of jack you want to have. Installation isn´t hard at all, I wanted to have AUX input on my car pannel so I had to drill a hole, but now it looks really cool. The device itself is smallest possible but works perfectly. I can only recommend ! Thank you for your services

As advertised

Beside a few annoying thing, it's OK

For VWCDPIC Audio Interface Adapter

First when I got it and built it in, it was not working! The seller / assembler has forgotten to solder 3 resistors. 3 components from the 8... It is almost 40% of the components.
They were the series resistors on the communication lines, so after connecting the VWCDPIC to the Mini DIN connector, nothing happened. The device does not even have a feedback LED or something that shows it is powered up. I had to disassemble the crimped cables from the connector house (it is not that easy and may cause permanent damage in the connector / crimps), cut the shrink tube, debug the whole PCB, solder the forgotten components, remake the electronic insulation and reassemble everything. Then it fortunately worked well.
You see, the device is good and the price is very favorable / fair. However I am not criticizing the product, only the fact it was neither double-checked nor functionally tested before shipment. I could solve it because I am an engineer, but what if an average person with lack of technical skills gets it?
One more thing: please use later a bit more detailed / more clear assemble guide not a photocopied, scraped one. You know, home made stuff can also have high quality and look professional...

Great product, works just as described

For VWCDPIC Audio Interface Adapter

Great product, works great - for anyone who wants to keep OEM look headunit and wants to have mp3 playback for way less then 3rd party headunit.
I bought one without preamp module as i have rooted samsung, with moded output level. I recommend testing your phone on some pc speaker system or audio amplifier / receiver / mini hifi, if you get enough level, then you can get by without preamp module.

Again on product, install took me some 15 minutes maybe, that is with removal of passenger side glovebox (for cable routing). Wires are easy to hook into, just take care in order not to mix up some pins.

It is so good i'll be ordering few more for other friends with stock Audi headunits, they will just test how their phones work in my car.

Thanks for this great little device :)

Breathing new life into older VW gamma tape deck!

For VWCDPIC Audio Interface Adapter

This was installed in a 2002 new beetle. Works wonderfully well!

I purchased both preamp and vwcdpic.

Shipping was quick and well packed.

I plugged in as per instructions and grounded both preamp and vwcdpic to tape deck housing.

And BAM! Amazing cd quality sound.

I purchased this because I like the stock look of the deck however I was surprised to learn that this thing (stock vw tape) really pumps!

Well worth the $$$

It's either this or a new stereo + trim piece kit = lots more $$$.
(Plus a crappy looking stereo)
