So do you want to install the new WiFi module on the old version of SBMS0 ?
Here is how the WiFi module for the old SBMS0 looks like and you can see the two optoisolators for IO5 and IO6 (the two 4pin black devices with the P187 written on them)
With the new SBMS0 those two optoisolators where moved to the main board so they are no longer on the new WiFi module and those two pins coming trough the 2x8pin black connector remain unused on the new WiFi module as seen in the photo below. You will need to add the two 1kohm resistors and the two optoisolators if you want to have access to IO5 and IO6 using the new WiFi module on the old SBMS0
