# 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) * 4P (+5/0, -5/0) ###### tags: `Regular Meeting` `DeWei`
