ALLNET BrickRknowledge I2C DA converter

The ALLNET BrickRknowledge I2C DA Converter (ALL-BRICK-0177) is a compact module that adds four channels of 12-bit analog output to your BrickRknowledge system. It uses the MCP4728 DAC IC, providing rail-to-rail output with internal or external reference voltage. The I2C interface allows easy integration with microcontrollers like Arduino or Raspberry Pi, with configurable address via onboard jumpers.

This module is ideal for applications requiring precise analog control, such as motor speed regulation, LED dimming, or sensor simulation. The 2.7-5.5V supply range ensures compatibility with both 3.3V and 5V logic systems. Each channel can be independently set to output 0V to Vref, with a typical settling time of 6 µs. The board includes a power LED and all necessary passive components for immediate use.
