CANABLOX® I2C External Power Injector (CX-INJECT-S)

The CANABLOX® I2C External Power Injector CX-INJECT-S will help you to provide more power to the I2C bus than your host (MCU) can deliver. For example, XIAO modules can deliver up to 200mA reliably on their 3.3V outputs when powered by 5V USB. If your bus devices require more then 200mA in total, you place the CX-INJECT-S module between your XIAO module and the rest of your circuit, and supply external 3.3V from the CX-DCDC-S module to the I2C bus. You connect the "HOST" side of the I2C bus to the MCU module, and the "BUS" side to the rest of your circuit. That way, you can draw up to 1.5A from the I2C bus, instead of only 200mA.

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.
