BIGTREETECH's Octopus Max EZ is a 32-bit motherboard with many interfaces for versatile upgrade possibilities. The main board is compatible with Klipper and Marlin as well as with a Raspberry Pi.
- 10 driver ports for versatile applications
- PS5450-5A enables direct power supply with a Raspberry Pi
- eFuse for a fast response and precise protection
- CNC fan voltage is freely selectable between 5, 12 and 24 V
- 3 x 4 pins fan port designed for water cooling
- 550MHz ARM Cortex-M7 STM32H723ZET6
8+2 EZ driver socket
Octopus Max EZ meets the normal operating requirements, but besides these, it also supports various improvements such as upgrading to a dual extruder or running the EZ-MAX31865. It also serves as a replacement in case of a burned-out driver port.
The main board is equipped with fail-safe EZ drivers, and has a protected chip and a pinless design, making it extra safe to use!
EZ5160Pro/EZ2209 can be connected without any trouble. Thanks to the integrated SPI and UART, you don't need any jumpers!
ARM Cortex-M7 STM32H723ZET6 for Marlin and Klipper
The 32-bit 550MHz ARM Cortex-M7 STM32H723ZET6 microcontroller is compatible with both Marlin and Klipper.
TPS5450-5A chip for power supply
The power supply chip supports DC12/24V power input and power output with a maximum continuous current of 5A and a maximum instantaneous current of 6A. The chip also enables a sufficient power supply for a Raspberry Pi.
The motherboard features eFuse, a high-end electronic fuse. When overload occurs, eFuse ensures faster shutdown; when the overload has been eliminated, it ensures automatic restarting. Highly accurate and requiring no special maintenance, eFuse protection detects any circuit failure, meeting incredibly high circuit safety standards.
Advantages at a glance:
- Quick shutdown in case of overload,
- Automatic restart when the overload has been eliminated,
- Operation at low currents,
- Overcurrent protection,
- Short circuit protection,
- Reverse current protection,
- Overvoltage protection,
- Reverse polarity protection.
Safety at the highest level
Octopus Max EZ has some new safety features:
- High-power capacitors support 56V output, MCU is protected by an isolation chip;
- Replaceable fuse with incredibly easy maintenance;
- High-efficiency MOSFET for reducing heat generation and increasing motherboard performance.
Supports a stable connection
►Heatbed (HB) and cartridge heaters (HE0-HE3) with high-performance power supplies: A tight connection between the power cable and the socket lowers the impedance and thus increases the efficiency of the power supply.
►CNC fan connection: freely selectable between 24, 12 and 5 V.
►Proximity switch connector: Support NPN/PNP type, freely selectable between 24, 12 and 5V.
DIY friendly for more upgrade possibilities
►FPC: For connecting a MINI12864.
►ADXL345 Interface: Connection of ADXL345 acceleration sensor to realise Klipper input shaping for higher printing precision.
►More expansion connections: CAN bus interface, simplifies wiring and offers high interface immunity. Supports power failure recovery, filament runout sensor, BLTouch, auto power off, RGB, etc.
►3 x 4 pin fan connector: Designed for water cooling systems.
Optimised user experience
►SD card slot: MCU firmware upgrade via SD card is possible.
►Onboard DIAG pin: easy to configure with a jumper.
►BOOT button: Onboard BOOT button to enable DFU mode for bootloader update.
With PC-grade PCB board, the printer's overall performance, heat dissipation and operation stability are greatly improved.
