Graviton Pin 27 BLTouch Adapter Black

Pin 27 BLTouch Adapter for Creality Printers

The Graviton Pin 27 adapter adds a dedicated sensor port to Ender 3, Ender 3 Pro, CR-10 and CR-10 Mini mainboards. It plugs between the board and the existing EXT1 ribbon cable so no wire cutting or soldering is required. The black PCB module routes power, ground and signal pins for a standard BLTouch or filament sensor. A firmware update completes the hardware installation.

Plug-and-play reliability under continuous printing

Once installed the adapter maintains a stable connection through long print jobs without the intermittent contact that can follow hand-soldered ribbon taps. The wider power channel on the PCB reduces voltage drop when the probe triggers repeatedly across large beds. Builders who run overnight or multi-day prints gain consistent auto-levelling data without rewiring the loom. The board stays seated even when the carriage vibrates at high speed.

Replaces ribbon-cable splicing for sensor upgrades

This module removes the need to cut the EXT1 ribbon and solder to pin 27, a step that risks damaging the mainboard and voiding the printer's original layout. The jump is worth it when adding a BLTouch or filament run-out sensor to a stock Creality machine and the builder wants a reversible, non-destructive install. It is not for printers that already expose a dedicated probe header or for users who prefer a direct soldered connection.
