Hello,
In my project, I’m using several M5Stack modules:

• ATOMIC PoE Base W5500 with Atom S3 Lite
• Extend I/O 2 Unit (STM32F0)
• 1 to 3 HUB Expansion U006
• Unit RFID2 SKU: U031-B

I’ve noticed that all of these modules feature 5mm diameter holes. Are these intended to serve as clearance holes for screws?

Additionally, how should I attach the ATOMIC PoE Base W5500 with the Atom S3 Lite if the two 5mm diameter holes will be obstructed by the Atom S3 Lite?
