   Do you mean the green board?   
      
   The blue box is the host for a variety of mezzanine boards. It can   
   host two if they don't have tall parts like this pot core.   
      
   The host has all the power supplies (including PoE) and uP and FPGA   
   and all that stuff. The CPU is a dual-core Raspberry Pi RP2040, which   
   configures the FPGA at powerup.
