Combo 8 is a development tool that combines the functions of a logic analyzer, CKLink Debugger, -Link Debugger, and USB2UART. You can switch functions at by pressing the button during use.<br> When used as a logic analyzer, it supports a maximum sampling rate of 80MHZ, and can cooperate with the host computer to analyze most protocols; when used as a UART module, it supports 4 serial ports at the same time, and supports a maximum baud rate of 20M, which can adapt to most scenarios where serial ports are used;<br> Use as CKLink or DAPLink It can be used to debug RISC-V series chips and ARM series chips, and additionally supports 1 serial port for observing logs.<br> function parameters<br> Logic Analyzer: Combo 8<br> Maximum number of channels: 8CH<br> Maximum sampling rate: 80M<br> Transmission bandwidth: 320Mb/s<br> Sampling mode: Stream<br> Typical configuration: 80M@4CH 40M@8CH<br> Signal input range: 0~3.6V<br> High and low level threshold: VIH 2V VIL Less than 0.8V<br> Note: The maximum transmission bandwidth of Combo 8 under environment is 160Mb/s, and the typical configuration is 80M@2CH 40M@4CH<br> CKLink function parameters<br> JTAG clock rate: 16M<br> Typical dump speed: 1200KB/s<br> Debug serial port: up to 20Mbps<br> DAPLink function parameters<br> Debug serial port: up to 20Mbps<br> Typical burning speed: 110KB/s<br> UART function parameters<br> High speed four serial ports<br> Maximum baud rate: 2x20Mbps+2x1Mbps<br> Total bandwidth: 42Mbps<br> Material: plastic<br> colour: White<br> Package Contents:<br> 1 x Combo 8 Analyzer<br> 1 x USB Type-C data cable<br> Only the above package content, other products are not included.<br> Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
