CANABLOX® Dual UART Serial Interface Module I2C (CX-2UART-S)

ETA: November 10-13, 2025 

The CANABLOX® Dual UART Serial Interface CX-2UART-S is an I2C to serial converter with 2 Channels in the CANABLOX® Form Factor "S" (Single Slot).

Selectable I2C address: 0x49, 0x4D
Max. UART Baud Rate: 115.2kbps

Code example:
Download a demo sketch (tested with XIAO ESP32C6) that sends a text string through UART-A and receives it through UART-B. Just cross-connect TXA with RXB and TXB with RXA and open the serial monitor in Arduino IDE to see the data (text) that was sent and received.
The header and comments within the demo sketches explain in high detail how it works.

This is in the bag:
1 x CANABLOX® module
1 x male pin header 4-pin
1 x screw terminal 5-pin
1 x CANABLOX® I2C Cable 5cm

Note:
Through-Hole (TH) connectors, like the I2C pin header or screw terminals, are included but not factory assembled.

The CANABLOX® ecosystem

CANABLOX® is a modular, clean, stackable ecosystem that replaces the chaos of traditional prototyping with I2C-connected building blocks.

CANABLOX® is not just a hobby tool; it’s a stepping stone from prototype to finished product. With over 60 modules envisioned, from environmental sensors to serial bridges and audio applications, CANABLOX® becomes a platform, not just a product.

Every CANABLOX® module connects directly to a sturdy baseplate or standardized cables, letting you build solid, real-world systems - without the clutter.

All modules use standardized CANABLOX® slot sizes and can be connected either through 4-pin JST-SH cables (compatible with Qwiic and Stemma QT) or by direct mounting onto the baseplate with headers. Every baseplate includes I2C headers (not assembled) and mounting hardware.
