The M5Stack DAC 2 I2C Unit (GP8413) is a compact and high-performance digital-to-analog signal conversion module designed for professional and industrial applications. Also referre d to as the M5Stack DAC 2 or DAC2 Unit, this device offers outstanding precision, scalability, and robust safety features. At its core, the DAC2 Unit utilizes the GP8413 chipset, capable of 15-bit resolution digital-to-analog conversion, outputting two independent analog voltages in the 0–5V or 0–10V range. With up to 0.01% linearity and a voltage error margin of only 0.2%, it ensures highly reliable and stable analog signal generation. Key Features of M5Stack DAC 2 I2C Unit (GP8413) 15-bit High-Precision DAC OutputConverts digital signals into two independent 0–5V or 0–10V analog outputs with exceptional accuracy. I2C Communication (Default Address: 0x59)Easy and reliable data transmission with support for multiple parallel connections thanks to a 3-bit hardware address, enabling up to 8 DAC2 Units on a single I2C bus. High Precision, Minimal ErrorAchieves 0.01% linearity and maintains a low output voltage error (0.2%), delivering professional-grade analog signal quality. Built-in Short-Circuit ProtectionProtects the module by automatically disabling output in case of a short between the output pins and ground. Compact, Reliable, and Expandable DesignPerfect for use in scalable IoT and industrial environments. Communication Protocol The M5Stack DAC 2 communicates using the I2C protocol, with a default address of 0x59. Thanks to address configurability, multiple DAC2 Units can operate simultaneously in complex systems, offering flexibility for advanced designs.
