Excellent new breakout board

[ger21]

A few months ago I was looking for a new breakout board for my UC300ETH, and came across the MB2 from CNC Room in Thailand.
http://www.cncroom.com/break-out-board/smooth-stepper

I'm using it with my UC300ETH and UCCNC, but it's designed to work with Mach3 and Mach4 and an ESS.

It's an extremely high quality board, and has a lot of really great features. It uses 3 ports on the ESS (and UC300), for a lot of inputs and outputs..
Here's some of the features:

24V I/O, with LED's on every pin.
Analog speed control
Differential step and direction
2 relays
Safety circuit

Here's a few pics with mu UC300ETH. I'll be making an adapter plate in a few weeks to mount the UC300 on top of the MB2, but for now, it's just sitting on my desk.

I am successfully using AM26LS31 for differential line driver on my Pokeys board similar to CNCroom boards. It works flawless for almost a year now

Thanks Danilo - I am on my way to build a Bob for the eding cnc CPU5a and was wishing to know what people around are using.

Looks like it's using AM26LS31C.

@Irfan: I use Eding CPU5b with Eding Bob.
