제목 : WIZ108SR(Old HW rev 1.1) Firmware v2.20

WIZnet mainly revised the hardware and software of WIZ107SR with the discontinuance of the main MCU, W7100, in November 2012

Since the hardware of the module for the old and new version are compatible, customers can replace the old version with new version without changing their existing hardware design.

However, the have to use the appropriate firmware according to hardware version. If they upload the wrong firmware, the module will not work properly.

 

This is the old firmware v2.20 for the WIZ108SR Rev1.1(using W7100 chip)
