But what is a big deal in this case is reliability: some of the sensors will be installed in locations where it would be an all-day trip to push the reset button, so it's important that there are no mystery gotchas in the drivers that cause the system to flake out once a week, or even once a quarter.

Hello Arduino-Forum,WIZnet proudly presents ....WIZ820io is an embedded Module using WIZnet's W5200 !!!WIZ820io: http://www.wiznettechnology.com/Sub_Modules/en/product/Product_Detail.asp?cate1=&cate2=&cate3=&pid=1161The W5200 + some externals + crystal is on the Bottom-Side of the small PCB. The footprint is 100mil = 2.54mm pitch.The two 6pin rows are 800mil = 8x2.54mm = 20.32mm wide. The PCB is 23mm wide and 25.62mm = 1inch long, the MagJack app. ~2.5mm overboard.best regards,Joachim Wülbeck
Who will adopt the driver first?
