Adafruit AS7262 6-Channel Visible Light / Color Sensor Breakout is a smart spectral sensing board built around the AMS AS7262. Instead of giving you only a basic RGB reading, it measures six distinct visible-light bands, making it useful for colour identification, reflected-light experiments, material analysis, and projects that need more detail than a standard colour sensor can provide.
The sensor provides dedicated channels covering violet, blue, green, yellow, orange, and red regions of the spectrum at 450nm, 500nm, 550nm, 570nm, 600nm, and 650nm. Readings are available over I2C as raw 16-bit values or calibrated floating-point values, which makes it easier to move from quick prototyping to more serious measurement workflows.
This breakout is designed as an all-in-one solution, with on-board firmware flash, a 3.3V regulator, I2C level shifting, and a built-in LED flash for reflective sensing. It also includes an on-board temperature sensor and breaks out both I2C and UART interfaces, with UART mode supporting AT commands and offering plug-and-play compatibility with the Adafruit FTDI Friend pinout.

This board goes beyond a bare sensor module by integrating the extra hardware needed for practical use. The pre-programmed flash stores the device firmware, the regulator simplifies power handling, and the level shifting helps when working with common development platforms over I2C.
The built-in LED flash is especially useful when measuring reflected light from surfaces or objects, helping improve repeatability in colour-detection projects. The on-board temperature sensor can also help with diagnostics and compensation in longer-running applications.
Please note: this is a visible-light spectral sensor breakout intended for electronics integration and development use. Interface selection and host-side software setup should be planned before deployment.
This breakout measures visible light in 6 separate spectral bands: 450nm, 500nm, 550nm, 570nm, 600nm, and 650nm. These correspond broadly to violet, blue, green, yellow, orange, and red light sensing channels.
The AS7262 supports I2C by default, and the breakout also brings out a selectable UART interface. It includes a 3.3V regulator and I2C level shifting on board, which helps when integrating it into common microcontroller setups.
Yes, the supplier mentions both Arduino library support and CircuitPython library support for this board. That makes it suitable for quick prototyping on supported development platforms.
The 6 channels can be read as raw 16-bit values or as calibrated floating-point values over I2C. The board also includes an on-chip temperature sensor for monitoring the sensor temperature.
Yes, it has an onboard LED flash intended to reflect light off objects for better color detection. This is useful in reflective sensing applications where ambient light may not be enough.
The supplier states that the UART pinout is plug-and-play compatible with the Adafruit FTDI Friend. The UART mode accepts AT commands when selected.
