WIZ750SR-TTL vs WIZ107SR-TTL


#1

Hi,

What is the difference between the WIZ750SR-TTL as compared to WIZ107SR-TTL?
Currently, I’m using the WIZ107SR-TTL, i wonder can i directly switch to use the WIZ750SR-TTL? Is this modules compatible with each other?

Thanks & Regards,
KS Lam

Some of the differences are:

    WIZ750SR is based on Cortex-M0 and WIZ107SR is based on 8051 MCU.
  • Some Pinout function

    WIZ750SR: Commercial (0~70)
    WIZ107SR: Industrial (-40~85) for H/W revision v1.3 or later.
