CANABLOX® 4-Channel 12-Bit DAC I2C (CX-MCP4728-S)

The CANABLOX® 4-Channel 12-Bit DAC CX-MCP4728-S provides four independent 12-bit DAC outputs with per-channel EEPROM to store settings (code, reference, gain, power-down). It offers an internal 2.048 V reference or VDD as reference, and supports simultaneous update of all channels (LDAC/general call). Ideal for multi-channel control, calibration, and waveform generation. The module is available in the "S" form factor (Single Slot).

Fixed I2C address: 0x60

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.
