Modular Integrated Klipper Mainboards Manta M8P V2.0, M5P, M4P, and Manta E3EZ

BIGTREETECH innovative Manta series motherboards—Manta M8P V2.0, Manta M5P, Manta M4P, and Manta E3EZ—combine a 32-bit motion MCU with a direct board-to-board mezzanine socket for the BIGTREETECH CB1 or Raspberry Pi Compute Module 4 (CM4).

This all-in-one Klipper architecture completely eliminates cumbersome external USB bridge cables and auxiliary power supplies, preventing serial communication timeouts during ultra-fast printing.

Manta boards feature Gigabit Ethernet ports, HDMI display outputs for native KlipperScreen interfaces, integrated CAN bus transceivers for toolhead communication, and heavy-duty driver sockets supporting standard StepStick and anti-misplug EZ driver form-factors for continuous automated manufacturing.

The clean monolithic layout optimizes cabinet airflow and wiring simplicity.

Trinamic Stepper Drivers TMC2209, TMC5160 Pro, TMC2240, and EZ Series

BIGTREETECH Trinamic-based stepper motor driver modules—including TMC2209 V1.3, TMC5160 Pro V1.1, TMC2240, TMC2226, and TMC2130, alongside the patented EZ driver series (EZ2209, EZ5160 Pro, EZ5160HV, EZ2240)—deliver precision microstepping up to 1/256 and whisper-quiet motion.

Trinamic StealthChop2 and SpreadCycle algorithms dynamically optimize coil currents to eliminate resonance and motor overheating. Sensorless homing via StallGuard technology enables physical-endstop-free axis calibration.

High-voltage EZ5160HV drivers support input voltages up to 60V and continuous currents up to 4.4A RMS for demanding NEMA 17/23 CoreXY gantries, while the anti-static EZ form-factor eliminates accidental short-circuits caused by reversed insertion or static discharges.

High-conductivity heatsinks are included with every module for optimal thermal dissipation.
