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. 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; 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 compatible with observing logs. function parameters Logic Analyzer: Combo 8 Maximum number of channels: 8CH Maximum sampling rate: 80M Transmission bandwidth: 320Mb/s Sampling mode: Stream Typical configuration: 80M@4CH 40M@8CH Signal input range: 0~3.6V High and low level threshold: VIH 2V VIL Less than 0.8V Note: The maximum transmission bandwidth of Combo 8 under environment is 160Mb/s, and the typical configuration is 80M@2CH 40M@4CH CKLink function parameters JTAG clock rate: 16M Typical dump speed: 1200KB/s Debug serial port: up to 20Mbps DAPLink function parameters Debug serial port: up to 20Mbps Typical burning speed: 110KB/s UART function parameters High speed four serial ports Maximum baud rate: 2x20Mbps+2x1Mbps Total bandwidth: 42Mbps Material: plastic colour: black Package Contents: 1 x Combo 8 Analyzer 1 x USB Type-C data cable 1 x Jump wire 10 x chip clamp Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
