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!
