breakout boards what are you using

Yep, definitely a good question, wilfy. I was asking myself that question last week when I managed to fry my previous pcpps board from diycnc. Entirely my fault, nothing wrong with the board.

After an evening of research I went for the v4 version of the same board. Its basic (no opto isolation, no led status indicators, charge pump doesn't directly disable outputs just sets a voltage you can use to do it yourself), and is perhaps a little pricey at £18, but its still the best option I could find. Below is my quick review having wired the new one up.

5v supply on board

So little documentation on the charge pump output (a key feature of the board) and how to use it that i, ummm, don't use it.
Documentation not great (how to connect to it? pull ups or pulldowns? how fast is it? Not much info on the web)
V4 mounting holes are a different pitch to V3
Outputs are inverted compared to V3 (not a huge deal, just re-invert in software)

Like I say, its the best option for my needs and I'm about to buy a spare, but the documentation really needs to be improved.

I too did loads of research when I was looking for a decent BOB and although a little pricey too at £110 delivered but ive had no problems with what is actually a well featured board and has ok documentation as well, Ive had about five now, with no problems ive not bought one for some time now so i suspect there is another version...

Opto-BB-V1
