We use these as a connection for our RTK GPS units on our irrigation machines and find them to be very reliable and great value.

Awesome component. It would be better yet if the inputs were 5 tolerant. Same advice for all of your 5V products.

It's not intended for sending photos but I do it routinely. A 320x240 image sends in about 6 seconds. It would be nice if it were faster but when I set it for more than 57.6 KBaud, the image is corrupted. Great product!

Project used Renzo Mischianti's EByte E220 library. E220-900T30D was easy to work with and performed to expectations. Renzo's E220 blog, articles helped with basic configuration, WOR, and structured messaging. Without Renzo's E220 blog articles; project would have failed!
