Awesome kit!
For Indoor & Outdoor Thermometer Kit
A blast to put together, clear and concise instructions and fun to see the animations! There's a very slight flicker on the two smaller displays (min-max), but it's not distracting enough to be a bother. The animations are amazing - I find myself just watching and waiting for the next one to happen. Everything about this kit is well thought out and I couldn't be happier with it!!

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

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