## Description

Review: Very happy so far - Used this to get an arduino talking to an industrial plc over modicon modbus tcp, possibilities are endless for custom sensors etc, description mentions that all these boards have the same Mac, if it causes me problems or I'm unable to change it will update and lower my review.
Review: Good product, good price, will buy again. - Came bundled with the Keyestudio Uno R3 and both work perfectly. The printing on top of the board (pin numbers, etc.) are a little harder to read than on boards from another manufacturer, but a bright light and a magnifier helped. This is a good product at a good price and I will buy these again.

### ⭐⭐⭐⭐⭐ It Works
*by S***N on September 4, 2018*

I bought the cheaper Smraza board sold on Amazon and it did not work so I returned it and bought another Smraza. The second one did not work, either, so I returned it, too. This one works perfectly!
