CANABLOX® ATmega328 MCU Module for Arduino (CX-AT328-MH)

The CANABLOX® ATmega328 MCU Module CX-AT328-MH is like an Arduino UNO R3 in the CANABLOX® Form Factor "MH" (2x1 Slot) and operating on 3.3V. You program it using the Arduino IDE and selecting the Arduino UNO board. Make sure that external devices use 3.3V logic level.

The on-board CH340K USB-UART provides connection to a host computer for programming, debugging and monitoring. Make sure you install the correct USB driver.

Code example:
Since this module is compatible with Arduino UNO R3 and Arduino Nano V3, you will find plenty of code examples for them. Select Arduino Uno in the board manager.

This is in the bag:
1 x CANABLOX® module
1 x male pin header 4-pin
3 x screw terminal 8-pin
1 x CANABLOX® I2C Cable 10cm

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.
