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. # Features * Dimensions: 154mm x 48mm * Based on STM32F407VET6 (168MHz Cortex-M4) * Supports CANBUS & USB communication * **Onboard Power Supply:** * Input: 24V @ 15A max * Onboard DC-DC power supply: 12V @ 3A, 5V @ 3A, 3.3V @ 0.8A * **5-channel Material Feeding Support:** * 5 onboard TMC2209 drivers, supporting 5 stepper motors * 10 general-purpose I/O pins for material insertion/extrusion monitoring * 5 dual I/O connectors for buttons and LED indicators (with level shifting) * **5-channel Hot Air Drying Support:** * 5x fans, support 2/3 fans, 12V/24V selectable, 2A Max * 5x heating interfaces, 5A Max * 5x NTC temperature sensor interfaces for temperature detection * 1x I2C interface for temperature and humidity sensors * 4x general-purpose I/O pins, use for external buffers * 2x Neopixel RGB interfaces for indication or lighting * Onboard BOOT0 and RST buttons * Independent input interface board # Wiring ## Powering The X5 The X5 board needs an input voltage of 24v for both CAN and USB connection methods. This can be supplied via either the DC Barrel Jack or Microfit3 connector on the X5 I/O board. ### DC Barrel Jack The DC barrel jack is 5.5\*2.1, and center-positive. This should be wired directly to 24v PSU of the printer. ![](https://raw.githubusercontent.com/FYSETC/wiki.fysetc/main/docs/images/crisp/chameleon-x5--dc-barrel-jack.png) | Barrel Jack | Value | | ---- | | RED | 24v | | BLACK | GND | ### MicroFit3 The microfit3 is a 2x2 female connector. This connector allows both the 24v and GND connections, as well as the CAN data connections. ![](https://raw.githubusercontent.com/FYSETC/wiki.fysetc/main/docs/images/crisp/chameleon-x5--microfit3.png) | Microfit3 | Value | | ---- | | RED | 24v | | BLACK | GND | | YELLOW | CAN H | | WHITE | CAN L | ## USB To use the Chameleon X5 on a USB connection, power the board with either the DC barrel jack or microfit3 connector and then connect the USB C cable from I/O board to the SBC (Raspberry Pi, Orange Pi, BTT Pi etc) of your printer. ## CAN To use the Chameleon X5 on a CAN connection. Use the microfit3 connector to supply both power and data using the diagram above to connect CAN H and CAN L to the corresponding CAN connection on your printer setup. # Wiring Examples ## 5 ways Heating and Drying example ![](https://raw.githubusercontent.com/FYSETC/wiki.fysetc/main/docs/images/crisp/chameleon-x5--ways-heating-and-drying-example.png) ## Type A usage example ![](https://raw.githubusercontent.com/FYSETC/wiki.fysetc/main/docs/images/crisp/chameleon-x5--type-a-usage-example.png) ## Type B usage example ![](https://raw.githubusercontent.com/FYSETC/wiki.fysetc/main/docs/images/crisp/chameleon-x5--type-b-usage-example.png) ## Type C usage example ![](https://raw.githubusercontent.com/FYSETC/wiki.fysetc/main/docs/images/crisp/chameleon-x5--type-c-usage-example.png) ## X5 I/O Board ![](https://raw.githubusercontent.com/FYSETC/wiki.fysetc/main/docs/images/crisp/chameleon-x5--x5-i-o-board.png) # Jumpers ||| ⚠️Waining ||| The USB 5V jumper is for facilitating firmware updates. Please remove this jumper cap when connecting a 24V power supply; otherwise, the ||| onboard DC 5V will be directly connected to the USB 5V, and if the motherboard malfunctions, it may damage your USB host device. ![](https://raw.githubusercontent.com/FYSETC/wiki.fysetc/main/docs/images/crisp/chameleon-x5--jumpers.png) # Firmware Guide ### Firmware Configuration and Compilation #### Using no bootloader ##### CANBUS communication mode ![](https://raw.githubusercontent.com/FYSETC/wiki.fysetc/main/docs/images/crisp/chameleon-x5--canbus-communication-mode.png) ##### USB communication mode ![](https://raw.githubusercontent.com/FYSETC/wiki.fysetc/main/docs/images/crisp/chameleon-x5--usb-communication-mode.png) ## Firmware Upload ### DFU Mode Firmware flashing can only be performed after entering DFU mode. How to get in DFU mode: 1. hold BT0 button for 2 seconds 2. Hold RST button for 2 seconds 3. Release the RST button 4. wait 2seconds 5. Release the BT0 button "lsusb" check if get in DFU mode ### No Bootloader Mode Upload Command： ```shell cd ~/klipper make flash FLASH_DEVICE=0483:df11 ``` # Attachments * [Schematic files](https://github.com/FYSETC/CHAMELEON_X5/blob/main/SCH/CHAMELEON_X5_SCH.pdf) * [Pinout File](https://github.com/FYSETC/CHAMELEON_X5/blob/main/SCH/CHameleon_X5_V1.0B%20PINOUT.pdf) For more documents including configuration information, please check https://github.com/FYSETC/CHAMELEON\_X5 # Support [Fysetc Discord Server](https://discord.gg/CtENXn9N) # Shop [AliExpress](https://www.aliexpress.com/item/1005011703032478.html)
