I have a TinyG v8, Everything works perfectly on it. Leads with 4 pin waterproof connectors are soldered to the board and glued in place. I need a board with smoothieware to run my laser for raster images. The TinyG isn't capable of raster imaging (well not very good at it anyway), however it excels at milling, fast operations, and moving heavy loads with it's S-curve acceleration profiles.
