UART test headers on PCBs provide access to serial debug consoles on embedded systems. The standard 4-pin 2.54mm header

SWD (Serial Wire Debug, ARM CoreSight) uses just 2 signals (SWDIO and SWCLK) plus power and ground for debugging and pro

cJTAG (IEEE 1149.7) reduces JTAG from 4-5 wires to 2 wires (TMSC and TCKC) using a serialized protocol. Saves PCB space

JTAG boundary scan (IEEE 1149.1) uses a 14-pin or 20-pin header to test PCB interconnects, program FPGAs, and debug embe

LXI (LAN eXtensions for Instrumentation) uses standard RJ45 Gigabit Ethernet and IVI drivers for controlling modern test

PXI Express (PCIe-based) uses a hybrid backplane combining PXI trigger bus with PCIe x4 or x8 high-speed data bus for mo

VXI (VMEbus eXtensions for Instrumentation) uses the VME P1 and P2 backplane connectors for modular test instruments in

GPIB-to-USB adapters (Keysight 82357B, NI GPIB-USB-HS) convert the 24-pin GPIB bus to a USB interface allowing modern co
