Description
The Adafruit GP8403 Breakout Board is a versatile DAC board capable of outputting 0-10V analog voltages, making it ideal for devices with wide voltage input ranges such as audio equipment or operational amplifiers. It features a built-in I2C-to-analog signal converter that converts 12-bit digital values into two independent analog voltage outputs of 0–5V or 0–10V. The board also includes a 12V booster, allowing you to power external devices with up to 100mA.

Key Features
- Outputs 0-10V analog voltages
- Built-in I2C-to-analog signal converter
- 12V booster for external power
- Non-volatile memory for voltage settings
- Compatible with STEMMA QT and Qwiic connectors
- Works with 3.3V or 5V logic
