From the project
Open Source Hardware JTAG/SWD/UART/SWO interface board
https://github.com/diegoherranz/steppenprobe
- Open Source Hardware and designed in KiCad. - FT2232H-based - Simultaneous operation of JTAG/SWD and UART/SWO. - STDC14 connector: standard Arm Cortex debug connector (1.27 mm pitch) with extra pins for UART. JTAG/SWD and UART on a single connector while being compatible with the standard Arm Cortex debug connector (middle 10 pins). - USB powered: no power supply needed. - USB type-C receptacle: more convenient (reversible) and future-proof (it should be the most common connector during the next few years). - OpenOCD compatible, supported from…
