OPL/2 is a fun toy.

For OPL2 Audio Board

I received the opl/2 as a kit. There was instructions on assembly and first use. BUT when it comes time to wire up to your controller, good luck. I first tried using wiring described by the assemble sheet, but no sound. I've spent a few hours trying to diagnosis a hardware problem. Finding the schematic didn't match the hardware. The clock was ok, serial to parallel was ok,
Hmmm not much remained. I was using a Raspberry Pi. I took a look at the source for the demo and saw different pin layout from the assembly sheet. Changed to demo pin connections but still no sound. Then I looked at the OPL lib source and found a third set of pin usage - and they worked. Maybe I should have ask when I found the first inconsistency?
Hardware to schematic or pin usage? It is a fun toy, now that it's producing sound.

Does what it promises! Very good product!

For OPL3 Duo!

I had OPL2 board already, so I had pretty good idea already about what to expect. It’s easy to wire and the sample code is a good starting point for own projects like VGM jukebox and FM synths.

Fantastic little board

For OPL2 Audio Board

The board is easy to solder. It's well documented and designed. Lot's of potential uses, definitely recommended.

nice layout and sounds great!

For OPL2 Audio Board

I bought this board for my Opera Rotas drum machine kit, great clear instructions and well layed out board.
works great and sounds awesome!
Shipping was slow but there is a warning on the page due to covid restrictions.
Thank you!

Awesome board!

For OPL3 Duo!

My plan is to make a diy version of Akemie's Castle, an FM synthesizer using YMF262 chips. While researching the chips, I discovered this product, and ordered it. It came within 1-2 weeks to the US, and I am amazed it survived international shipping. All the examples work perfectly out of the box! Together with the awesome library of examples from DhrBaksteen's Github page, I think my project will be very feasible. Great product and great value, brought to the Arduino ecosystem!

Super nice kit

For OPL2 Audio Board

OPL2 was the first computer generated music I made when I was younger. So nice to have this as a module now. Works perfect.

Jason | Feb. 27, 2021

Works Great!

For OPL3 Duo!

It works as advertised and the documentation is really well put together. Integration was easy and the sound is great!

Shipping time was less than 3 weeks from order to arrival.

Works Great!

For OPL2 Audio Board

I was a little disappointed the YM3812 was sanded and repainted; most are nowadays but I had hopes. The device and documentation are spot on. I have no complaints and it fits my needs perfectly! Didn't have a need to communicate with seller since documentation was well put together. I'm happy with the purchase!

Shipping was less than 3 weeks from order to arrival.

The Way It Should Be™

For OPL2 Audio Board

First time purchase on Tindie; I'm very impressed. The board is good quality, using good quality components. It worked straight after soldering, no fussing around required. The examples in the documentation work very well, I had no issues. If I had to give one slightly negative remark it's that the hole spacing for the mounting holes isn't on a 2.54mm pitch, so it's a bit hard to mount it to a strip board.

I used the board to build a MIDI instrument for my modular synth. The library gives plenty of options to play with the instruments in the library or create your own. Audio quality is good. I haven't heard any appreciable noise (after giving the board proper ground).

The schematic that I found on Hackaday seems to be for an earlier version of the board. I needed some adjustments in the final amplifier to match my synths volume levels, so I had to do some reverse engineering there.

Kilian | Feb. 4, 2021

Again an excellent product

For OPL3 Duo!

After previously having bought the OPL2 board, couldn't resist buying the OPL3 Duo. Excellent board quality again, and very easy to setup with the instructions and examples provided. Got my DRO code ported from the OPL2 version in less than five minutes. Shipment was fast, but then again, I live in the Netherlands too, so no crossing borders.

Alex | Jan. 26, 2021

It's great!

For OPL3 Duo!

Works as advertised, good library + demos on github. Seller is responsive to pull requests + issues on github as well.

Tim | Jan. 22, 2021

double the fun!

For OPL3 Duo!

I admittedly haven't really had too much of a chance to play with this board beyond example sketches to just verify it works, but side-by-siding the demo song against the opl2 audio board, i imagine it must be what it felt like to upgrade a sound blaster 2.0 to an awe32 or adlib gold.

Tim | Jan. 22, 2021

impossibly delightful

For OPL2 Audio Board

This brought me right back to my sound blaster 2.0, precisely as i had hoped. instant nostalgia. very simple to get up and running on an arduino. shipping was unexpectedly fast, precisely 20 days from order to delivery in USA. can't truly rate communication because i've had none with the genius who creates these, but given the quality of everything else i can't imagine it'd be less than stellar, so i extrapolated based on the github repo readme and issue tracker.

Minsung | Jan. 14, 2021

Easy, works perfectly!

For OPL3 Duo!

It's a great product.
I want to thank the creators.
Excellent sound quality, easy assembly, and functionality.

Benjamin | Jan. 13, 2021

Clear sound, simple construction, max value!

For OPL2 Audio Board

Built it, jumpered it, uploaded the test program, and it just works!
If only the rest of life was this easy and fun.

Taehyun | Dec. 4, 2020

Better analog amp quality than OPL2 audio board.

For OPL3 Duo!

It takes 1 month to get board.I think covid-19 situation may affect delivery processes. It is better to provide more option for shipping ( track is required )
Beside of that, overall quality is very good. I love to hear FM sound from OPL3 using my arduino.

Great board

For OPL2 Audio Board

Beautiful and easy to assemble all-through-hole PCB. Great example code available through the Arduino app and on GitHub. It’s especially nice that a second set of chips is optionally available.

Vaclav | Sept. 9, 2020

Easy to build, works perfectly!

For OPL2 Audio Board

Great little kit, comes with nicely done documentation. Easy to build, since all components are THT. The kit I built worked out of the box, the examples and library listed at GitHub page worked with my Arduino Nano Every without problems...
In less than two hours since opening the package with the parts I've been playing my favorite VGM tunes from SD card, that's a success I think! (Again, via an example provided by the library.) Thank you!

Erik | Aug. 31, 2020

This is a pretty cool project and was fun to build

For OPL2 Audio Board

It's a pretty straight forward layout and worked with my Arduino IDE with the Arduino UNO board. The only critique would be to add a second set of power (5V and ground) pins along with a second Data and Shift pins (MOSI and SCK respectively) for hooking up a microSD card breakout board for the UNO, but even without it, it was still easy to hook that up as well. Loving the old Ultima 6 tunes!

Amazing product!

For OPL2 Audio Board

It's quite amazing to hear some of that old game music playing with such clarity through modern speakers. Wish I had, had this setup back in the day. Great product and great communication from a seller that clearly cares about the product they have produced. Now to make a fun project with the board. Thanks

Works perfectly!

For OPL2 Audio Board

Tested with Arduino Uno R3, works perfectly, drums and music.
The hardware works fine directly from the start.
The manual could be improved and we have discussed this.
We ordered immediately more of these boards for educational purpose.
I recommend this board to everyone who likes to add music to the embedded experiments or projects. And yes I am sure it works also on your Raspberry Pi.

Thomas | March 15, 2020

Very useful board

Love it

For OPL2 Audio Board

Arrived very fast, I'm very thankful for this fully assembled kit, saved me so much time. Assembled easy, but the pinout instructions on the printed info (included with the kit) for the Teensy++ 2.0 was A0-> C6 and I got no sound, whereas this page (https://github.com/DhrBaksteen/ArduinoOPL2/wiki/Connecting) has the A0 connecting to E1 and Voila I had Sound !!! I'm aware these settings can be changed in software but this is for people ( like me ) who aren't very familiar with Teensy programming. I had no luck with the OSX version of the Opl3 bank Editor program, but I tried it on a PC running XP. I needed to install the Teensy Usb driver found here: https://www.pjrc.com/teensy/serial_install.exe. got the OPl3 bank editor running, it recognizes my new Com port, I load Instruments.. and every instrument had a slight distortion ( a fizzy/hissing sound) most obvious with quieter instruments. I tried adjusting the volume pot on the board but it's present at any volume.

UPDATE:
Maarten contacted me with info on how to test the LM386 amplifier chip which appears to be damaged making that noise. Now I can hear a beautiful clean signal produced by that fantastic YM3812, I'm so happy now. Thank you Mr. Janssen you are a genius.

Super recomendable

For OPL2 Audio Board

The build is as easy as it can get.

It sounds 100% like the real thing, because it is the real thing, no emulators here.

And it comes with a lots of examples so you can use it with your arduino, teensy, rasperry and even with a OPL3 Bank Editor than runs in the computer. I had a little problem setting up this one ans Maarten has solved the doubth in no time.

Also, the packet arrived in less than a week and the packaging was delicious. So Im so happy with this board and I recommend it to anyone that is reading
