MANTA M8P V1.1: Powerful Motherboard for 3D Printers

Manta M8P v1.1 is a universal 32-bit motherboard with 8 slots for motor drivers. This makes it suitable for Voron 2.4, Trident, and other machines (such as VZBOT) that require control of more than just the standard 4 or 5 motors. It features a slot for easy connection of Raspberry PI CM4 or BTT CB1, simplifying the wiring considerably. Additionally, there's no need for an additional power source for the Raspberry. It offers a wide range of connectors and ports for connecting additional accessories, although compared to the Octopus board, there are fewer of them, as some connectors had to make way to integrate the CB1 connector.

Main Benefits

• High Performance: The heart of the board is a 32-bit ARM Cortex-M0+ STM32G0B1VET6 processor with a frequency of 64 MHz, ensuring fast and stable performance.
• Power Supply: TPS5450-5A power chip supports DC12/24V input voltage with an output current of up to 5A, ideal for Raspberry Pi.
• Flexible Configuration: It offers the possibility of updating the bootloader via DFU, a protective circuit for thermistors, and support for PT1000 without an external module.
• Expandability: The board has rich expansion ports for various modules such as BL Touch, LCD screen, RGB lighting, and automatic shutdown.
• Security Features: Including eFuse circuit protection for quick response and protection against overload and short circuit.
• Dimensions and Compatibility: The product dimensions are 170 x 102.7mm, and it is compatible with a wide range of printers.
• Optional Fan Voltage: 5V/12V/24V
