BIGTREETECH Manta E3EZ V1.0 for Ender 3

The BIGTREETECH MANTA E3EZ V1.0 is a motherboard developed by the 3D printing team of Shenzhen Bigtree Technology Co. to help you to take your Ender 3 to the next level whether that means running Klipper or even Marlin with all of the latest features. This is our first motherboard that incorporates “Manta” technology (B2B connectors for the CB1 or CM4 modules) and “EZ” technology (the ability to use the latest EZ drivers). Simply plug in the CB1 core board and EZ drivers on the motherboard to upgrade your Ender 3 printer to run Klipper. Due to there being no need for an external raspberry pi the Manta series saves you messy cabling and results in a highly compact implementation.

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.
14. The motor power supply supports up to 56V, and for the larger voltage when using EZ5160, an isolation chip is used to protect the main control from burn

The Manta E3EZ is directly compatible with the Ender-3. Since we crammed so much into this board, we were unable to keep the size 100% compatible with other Ender machines and so minor, printable adapters are required. To check if your machine requires an adapter, see this link:
