I see that this product has been discontinued.
Are there plans to create an updated replacement for this board?
Would the replacement be designed for the PI B+?
Would it use a different chip?
When might a replacement be available?

Will this help?

Wait until all output written to file descriptor fd has been transmitted."
I am interested in the new board design using the Max13487. Will Sparkfun be carrying these soon? If not does anyone know where I can find one or find the design and parts? I've been messing around with the 485 breakout board now for about a month and it is extremely difficult to get reliable fast communication. At best so far I'm only able to get communication speed to about 1/3 as fast as it should be and I still have some errors. When I use a USB to 485 it works flawlessly, except I don't want to use USB for the finished product.
No public wish lists :(
