# Regular Meeting (2022.9.19)

* CDCFE Fanout Baord
* Zybo-z7
  * Assembly rootfs
## CDCFE Fanout Baord
* [TestReport for CDCFE-Fanout-Baord V0.1:<br> Measurement and grounding issue](https://hackmd.io/@BelleII-CDC-Trig-NTU-DeWei/HJtU2AUes)
* Next version (if has): 
	* Add over-voltage-protector(OVP), such as *zener diode*
		* Because small size Ceramic(0603) has low max voltage <br>(~7V, our remaining capacitor almost is this max-voltage)
		* A capacitor has been breakdown(short) in last week
	* Sma-input -> u.fl to sma screw into chassis
	  * Since we'd like to apply chassis solved grounding noise
* I will complete Aluminum chassis this week
	* Tapping for power and signal
		* Chassis(thick metal) is necessary for V0.1 fanout board
		* Yes...that's failed design on the *aspect of product*
			* Maybe V0.2 we could condider how to solved ground problem without thick metal chassis
* About connector for chassis 
	* [Power: GX-16 Aerospace connector](https://shopee.tw/GX12-GX16-GX20-%E8%88%AA%E7%A9%BA%E6%8F%92%E5%BA%A7%E6%8E%A5%E9%A0%AD%E6%8F%92%E9%A0%AD%E6%8F%92%E5%BA%A72-3-4-5-6-7-8-9-10-12%E8%8A%AF%E9%9B%BB%E7%BA%9C%E9%80%A3%E6%8E%A5%E5%99%A812MM-16M-i.149365831.7019612924)
