The Chameleon X5 can be used in various multi-color applications requiring multiple motors to work together, such as Type-A, Type-B, and Type-C systems. It also includes the necessary fan/heating control and temperature detection circuits for heating and drying functions.

It is based on the STM32F407VET6 microcontroller and TMC2209 stepper motor driver chip, with each channel equipped with the necessary I/O interfaces for filament input/output monitoring and status indication (buttons and LEDs) to ensure stable feeding.

The optional 5-channel heating and drying function includes dedicated interfaces for fan control and heating elements, as well as NTC temperature measurement, and also supports I2C sensors, such as temperature and humidity sensors.
