LabJack provides a good stand-alone controller solution for fast development projects.
LabJack has overall been a good experience. Their products work, and they have available customer support (chat) that makes getting answers easy. We are a sub-contractor that was told to use LabJack T7 controllers in our products. We found out after a while that the T7 was too large for our application (even just the PCB assembly). We had to transition at the last moment to the T4 (board only) and get creative with our many digital I/O (which we had to wire into a matrix to minimize the I/O lines we used). We had planned to use the daughter boards but they also would not fit. Luckily, LabJack had the forethought to provide the DB15 connector with most of the I/Os provided, and we were able to find a flat cable assembly to break them out and wire in our application. The T7 provides the same I/Os on its DB15 connector, which allows you to "move up" from the T4 easily. The I2C interface worked but be sure to provide pull-up resistors! I was impressed with their quality and how well the test program worked with the T4 and T7 to shorten development times and speed up the testing process. If you are short on time, LabJack will get you to the finish line.
