DCC-EX CSB1 Qwiic to JST I2C Expansion Cable

Direct I2C Expansion Cable for DCC-EX CSB1

Connect compatible JST-based I2C expansion boards directly to your DCC-EX CSB1 using the Qwiic connector found on the EX-MotorShield8874 and other supported DCC-EX hardware.

This pre-configured Qwiic to JST I2C expansion cable provides a simple and reliable way to connect compatible I2C expansion devices directly to the DCC-EX CSB1 command station.

Designed for use with the ACI I2C Expansion Board and other compatible JST-connected I2C modules, this cable provides a ready-to-use connection between the CSB1 Qwiic / STEMMA QT port and JST-equipped expansion boards without requiring custom wiring or connector modification.

Ideal for connecting the ACI I2C Expansion Board to the DCC-EX CSB1, while also supporting other compatible JST-connected I2C devices used for layout expansion and automation.

Each cable is manually prepared and configured to simplify installation, helping reduce wiring complexity while making future expansion of your DCC-EX system easier.

Cables are made to order and supplied in a practical 150mm length suitable for most control panel and layout installations.
