    This only drives to rs485 bus for one state of the transmit data. It won’t work unless somewhere else on the rs485 bus it is biased so the other state is the default. And forget about high speed or long lines. I expected better from Sparkfun… Wouldn’t be hard to wire the driver enable to another pin of the arduino. Most other designs I have seen use digital pin 2. At least one (mentioned below) uses a retriggerable timer circuit so specific code to control the transmit enable line isn’t needed.

No public wish lists :(
