In the website's catalogue ther are two options, namely AES-ULTRA96-V2-G (https://www.avnet.com/shop/us/products/avnet-engineering-services/aes-ultra96-v2-g-3074457345638646173/) and AES-ULTRA96-V2-I-G (https://www.avnet.com/shop/us/products/avnet-engineering-services/aes-ultra96-v2-i-g-3074457345642820668/)
Given the notable price tag difference between the two models, I am wondering what are the main differences between the two boards, since none are observed from the description nor the pictures.
