Overview

The Yahboom color recognition module uses a ZC-CLS381 professional color recognition chip to judge different colors by detecting RGB values. Compared with an ordinary grayscale sensor module, it is less affected by the environment, with a wider recognition range and faster recognition speed. The module communicates via I2C and supports three wiring methods: alligator clip connection, DuPont line connection, or PH2.0 cable connection.

A tutorial video is included below. For product support, contact https://rcdrone.top/ or email support@rcdrone.top.

Key Features

  • On-board ZC-CLS381 professional color recognition chip (RGB-based color judgment).
  • I2C communication (SDA/SCL).
  • Three connection methods: alligator clip interface, DuPont line interface, PH2.0 cable interface.
  • MakeCode graphical programming support.
  • Interface design notes:
    • Side row female interface advantages: not easy to short circuit; flat profile for multi-level connection; does not affect the user experience of button modules.
    • Four-corner alligator clip interface: clips are far apart at the four corners, not easy to short, suitable for fast connection.
    • PH2.0 foolproof interface: keyed insertion for easier use.
  • Default assembly note: the module has been soldered to the DuPont interface and PH2.0 cable interface by default.

Yahboom ZC-CLS381 I2C color recognition module RGB sensor board with VCC/GND/SDA/SCL pads

The ZC-CLS381 chip reads RGB values over I2C to help micro:bit projects detect and classify colors.

Interface feature overview highlighting side-row header, four-corner alligator pads, and keyed PH2.0 connector

Three connector styles make wiring flexible for classrooms, prototypes, and tidy final builds.

Alligator-clip wiring example between micro:bit board and the color sensor module for quick connections

Alligator clips are spaced at the corners to reduce shorts and speed up testing with micro:bit.

DuPont jumper wiring example linking the color sensor module to a controller/expansion board via I2C pins

Use standard DuPont jumpers for breadboards and common development boards that expose SDA/SCL.

PH2.0 cable connection example from the color recognition module to an expansion board with keyed plug

The keyed PH2.0 cable connection helps keep polarity consistent and setup simple.

Optional DuPont jumper wire sets in multiple colors for connecting sensor modules to development boardsOptional PH2.0 cable lead for connecting the module to compatible expansion boards and sensor hubsCompatibility collage showing the module used with multiple main control boards and expansion boards

I2C support makes the sensor easy to integrate across many controllers and expansion boards.

Comparison graphic: grayscale sensor vs Yahboom ZC-CLS381 color recognition module with wider range

Compared with a typical grayscale sensor, RGB-based recognition is designed to be less sensitive to ambient changes.
