DFRobot Gravity 1-Channel 15-Bit I2C DAC Module With Selectable 0-2.5V/VCC Output High-Resolution 15-Bit I2C DAC to Analog Voltage Converter For Analog Control

Description:

This compact, single-channel analog voltage output Digital-to-Analog Converter (DAC) module leverages the simplicity and ubiquity of I2C communication for seamless integration with a wide array of popular 3.3V microcontrollers, including the ESP32, Raspberry Pi, and STM32 families. Boasting a high 15-bit resolution, this module enables fine-grained control over the output voltage, achieving an impressive 0.01% precision. This level of accuracy renders it particularly advantageous for control projects demanding precise analog signal generation. Imagine the smooth, nuanced adjustments achievable in applications like fine motor speed regulation or precise angular positioning.

As part of a versatile DAC series, this module exemplifies a broader family of products designed to generate either voltage or current output signals through convenient I2C or PWM control interfaces. This comprehensive series caters to diverse application needs by offering a spectrum of output signal ranges and providing a choice of three distinct resolutions: 8-bit, 12-bit, and the high-precision 15-bit option featured in this particular module. Furthermore, the series offers flexibility in channel configuration, with both single-channel and dual-channel options available. For applications requiring an even greater number of analog outputs, the modular design allows for the cascading of multiple DAC units, enabling the creation of sophisticated multi-channel output systems.
