| Digital board | 2.56x5.265" | ||
| Power and communication | 2.56x5.240" | ||
| Carrier | 2.56x1.95 | Can we do it smaller? What is the minimum amount of components that need to leave in this board | |
System level power requirements for carrier (what are the specs for the voltage regulator and what is the number of regulators per power)

Goal is to have a decision on the FPGA package and family.
Kintex Ultrascale+ vs Virtex?
Notes:
- FPGA intercommunication
- co-design with the data reduction pipeline
- DFX for streaming pre-processing and eventually microAI, reusable building blocks
