I first came to learn about Supermicro's E100-9W platform last year, which I had first written about here. The E100-9W is a fanless kit that is part of Supermicro's Embedded IoT family and targets similiar use cases to the Intel NUC such as Industrial Automation, Retail, Smart Medical Systems, Kiosks and Digital Signage. Although the E100-9W was just released in 2020, it was actually using a much older Intel 8th Generation CPU due to some constraints with Intel's embedded CPU roadmap.
Supermicro did mention last year that a Tiger Lake-based model was in the works and last week, I just got my hands on a pre-production unit for their 2nd generation of this platform called the E100-12T.
