JST XH 2.54mm 4-Pin Both-Sided Connector Cable — Same Side & Reverse Polarity, 22AWG
The 4-pin JST XH 2.54mm both-sided cable is the workhorse extension cable for I2C buses, SPI interfaces, stepper motor connections, and any 4-wire interface that needs to be extended, routed, or adapted between two PCBs. Both ends arrive factory-crimped and ready to insert into XH housings — no additional assembly required. Available in Same Side (straight-through, pin 1 to pin 1) and Reverse Side (mirrored, pin 1 to pin 4) configurations to match the connector orientation required by your specific application.
The 4-pin format is particularly critical in I2C applications, where pin order (SDA/SCL/VCC/GND) must be preserved exactly. A reversed cable on an I2C bus will either fail to communicate or, in the worst case, apply power to a signal line and damage the connected device. Ordering the correct polarity configuration eliminates this risk entirely.
Eight contacts (four per end) are machine-crimped to a defined pull-force specification, inspected, and shipped ready to use. The positive latch lock on both ends ensures the cable stays seated under vibration and repeated handling.

Same Side vs. Reverse Side — Which Do You Need?
Same Side (Straight-Through): Pin 1 connects to pin 1 at both ends. Use for I2C bus extensions, SPI extensions, stepper motor cable extensions, and any application where both connectors face the same direction with identical pinouts.
Reverse Side (Mirrored): Pin 1 connects to pin 4 (and pin 2 to pin 3). Use when connectors face opposite directions, or when the PCB layout requires a mirrored pinout at one end. Common in 3D printer stepper motor extensions and display module connections where the connector orientation is flipped relative to the PCB.
Typical Applications
- I2C Bus Extensions: OLED display extensions, RTC module connections, IMU sensor extensions, environmental sensor leads (SDA/SCL/VCC/GND)
- SPI Interface Extensions: SD card module extensions, display driver connections, ADC/DAC module leads
- 3D Printers: Stepper motor extension cables (X/Y/Z/E axes), BLTouch/CR Touch probe extensions, filament sensor extensions
- Arduino & Microcontrollers: Multi-wire sensor module extensions, shield-to-module connections, breakout board leads
- RC & Drones: Flight controller I2C peripheral extensions, compass module leads, barometer connections
- Robotics: Encoder quadrature lead extensions, motor driver interface cables, servo bus extensions
- Industrial: 4-wire RTD sensor extensions, multi-channel analog input leads, PLC I/O extensions
Compatibility
Both ends are compatible with JST XH series 4-pin housings (JST part: XHP-4) and all 2.54mm pitch PCB headers with XH-compatible locking geometry. Cross-compatible with third-party XH-style connectors.
Housings not included. This listing is for the pre-crimped cable only. Select your required polarity (Same Side or Reverse Side) and length from the variant options above.
