Hello Arduino-Forum,
WIZnet proudly presents ....
WIZ820io is an embedded Module using WIZnet's W5200 !!!
The 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
