## Zybo-z7

* Building image......

## CDCFE Fanout Baord

### Finished layout

* OPA3692 (Fixed resistor inside buffer)
* OPA2674 (Tuned resistor)
* Pass DRC(Design Rule check) from the EDA-SW (No Err/Warnning)
* Price:
* MF help us merge board -> 10k NTD
* We merge (stamp hole) -> 5k NTD
* Yes....prices have gone up than previous years
