board delivers, but misses some finishing user features

The board provides the required interface but leaves off just short of a "full" product. The component designations of the resistors are covered by the parts. Seeing how there is plenty of room on the board, the designators (R1, R2, D1, ...) should be put somewhere you can see them when the parts are installed. Sometimes you're working in a 3.3V system and the resistor values for that environment (47 ohm) for the series resistors on the MIDI output would be a nice-to-have. I don't know that this could hurt performance, but there is a pull down resistor sometimes used in circuits for the provided opt-isolator pulling down that unused pin; I added a 10K pull down to pin that for good measure. Some of the resistors, with a fairly sharp bend in the leads, don't fit easily into the PCB. Again, with room on the board, the spacing should be ample for the insertion of the parts and not cramped for no reason.

Good stuff, easy to assemble, easy to use, but not cheap!

I would buy it again because of short delivery time, but other companies are cheaper. Anyway, it is a good choice, works without problem.

Well done but same shortcomings as the competition

This board is well designed, the instructions are great and it arrived quickly. What I would really like to see in a MIDI Breakout Board is less of the "me too" sameness that so many of these have, and a little more of the "designed better" that this market really needs. I think this is a reasonable request and this designer could easily accomplish it. First it needs to have a buffered output. This is the way the official MIDI spec was written and I won't buy a MIDI Breakout Board again that doesn't have it. By the way, this is the third such board I have investigated. Second, it would not be hard to add optional MIDI activity LEDs. By adding a one 7414 and some high efficiency LEDs both tasks could be accomplished. I hope this designed takes my recommendations to heart. On the other hand, if you just want a minimal board, this will do the trick.
