Product Profile
BIGTREETECH MANTA E3EZ V1.0 is a 32-bit motherboard developed by the 3D
printing team of Shenzhen Big Tree Technology Co., Ltd. for Ender-3, Klipper running,
and EZ series drivers. It is compatible with Ender-3 motherboard mounting holes. Simply
plug in the core board, and your Ender-3 will be able to run Klipper, greatly eliminating
the mass wiring between the motherboard and Raspberry Pi, and also greatly saving space
in the chassis. The BTB headers are designed on MANTA E3EZ V1.0, so that customers
can choose to use CM4 or other solutions, thus solving the insane shortage of Raspberry
Pi CM4.
Feature Highlights
1. 32bit 64MHz ARM Cortex-M0+ series STM32G0B1RE MCU.
2. TPS5450-5A power supply chip supports DC12/24V power input, current output
rated at 5A max continuous and 6A max instantaneous, sufficient power supply for
Raspberry Pi.
3. The thermistor circuit is protected to prevent MCU damage from shorted heated bed
and heater cartridge connections.
4. MCU firmware can be upgraded via SD card, or use DFU via Klipper's make flash
command.
5. BTB connectors are adopted between the motherboard and core board, allowing the
choice of other core board solutions in addition to CM4.
6. Onboard SPI and UART mode of EZ driver, which can be used directly without a
jumper.
7. Onboard DIAG pin, easily configurable with jumpers.
8. Support power loss recovery, filament runout sensor, auto power-off, BLTouch, RGB,
etc.
9. High-efficiency MOSFET for less heat generation.
10. Replaceable fuse for easy maintenance.
11. Onboard SPI interface for connecting acceleration sensor to enable Klipper's input
shaping.
12. The temperature sensor interface adopts a high-precision pull-up resistor.
13. Each motor driver module can select the corresponding motor voltage by jumper
caps.
