README
README.mdUINIO-Logic-24MHz 逻辑分析仪
UINIO-Logic-24MHz 是一款基于英飞凌（已收购赛普拉斯 Cypress）的 CY7C68013A 型 USB2.0 控制器，以及 Sigork 开源固件方案的逻辑分析仪电路设计。拥有 24MHz 采样频率，以及 8 个采样通道。
设计概要
- 采用 USB Type-C 接口，以及
10 Pin的牛角插座； - CY7C68013A 型 USB 控制器芯片采用了体积较小的
QFN56封装； - AT24C64 微芯 EEPROM 存储器芯片同样采用体积小巧的
TSSOP8封装； - 板载
24MHz无源贴片晶振，阻容贴片元件全部采用0402的小规格封装； - 增加具有三态输出功能的 74HC245 八路信号收发器，提升信号采集的稳定性；
- 低压差线性稳压器可以灵活选用
ME6211C33M5G或者A6303AE5R-33A等SOT23-5封装的 LDO 芯片； - USB Type-C 接口位置新增一组 TVS 瞬态电压抑制二极管；
注意事项
- LED 指示灯
D2连接至 CY7C68013A 的PA0引脚，而D3则被连接至PA1引脚； - 需要结合 Sigork 的开源固件 sigrok-firmware-fx2lafw，并且搭配 PulseView 上位机协同使用；

Questions
How big is the UINIO Logic-24MHz PCB?
It measures 52 × 25.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the UINIO Logic-24MHz use?
55 parts, built around the CY7C68013A-56LTXC, 74HC245C, AT24CS64-XHM-B and ME6211C33M5G-N. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the UINIO Logic-24MHz KiCad files?
From the uinika/UINIO-Logic-24MHz repository on GitHub, at the commit this page was made from: the board is UINIO-Logic-24MHz.kicad_pcb and its schematic UINIO-Logic-24MHz.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the UINIO Logic-24MHz design in my own project?
Its repository states no licence, so its author keeps all rights: ask uinika before reusing the design.
