BIGTREETECH Manta M8P V2.0
The BTT Manta M8P V2 combines an STM32H723 running at 550MHz with 8 stepper driver slots and an onboard CM4-compatible SBC socket in a single board. Supporting CANFD, high-voltage drivers up to 60V, and direct CB1/CB2/CM4 mounting, it eliminates the need for a separate Raspberry Pi in Klipper setups.
The modern integrated choice for Voron builds — pay more upfront, save on a separate SBC.
Where to Buy
Pros
- STM32H723 at 550MHz is 3× faster than the Octopus V1.1's STM32F446 at 180MHz
- Onboard CM4/CB1/CB2 socket eliminates a separate Raspberry Pi and USB cable
- CANFD support at up to 5Mbit/s — 5× faster than standard CAN bus
- High-voltage driver support up to 60V enables TMC5160 with 48V steppers
- Integrated 5V/3A regulator powers the SBC directly from the main 24V supply
Cons
- At $99, it costs $34 more than the Octopus V1.1 (before adding an SBC)
- CM4/CB1/CB2 sold separately — the SBC socket adds $35-$45 to total cost
- Newer design means fewer community configs compared to the Octopus V1.1
- Similar footprint to the Octopus (170x102mm vs 160x100mm) — no meaningful space savings
Processing Power and SBC Integration
The STM32H723 Cortex-M7 at 550MHz makes the Manta M8P V2 the fastest 3D printer mainboard in its class. For context, the Octopus V1.1's STM32F446 runs at 180MHz — the Manta has over 3× the clock speed. This matters for Klipper's input shaping calculations, which run on the MCU and benefit from faster processing.
The CM4-compatible SBC socket accepts a Raspberry Pi CM4, BTT CB1, or BTT CB2 directly on the board. The CB1 at $35 is the cheapest option and provides an Allwinner H616 quad-core running MainsailOS. The CB2 at $45 upgrades to a Rockchip RK3566 with 2GB RAM and Gigabit Ethernet. Power for the SBC comes from an integrated 5V/3A regulator, so no separate USB power supply is needed.
CANFD and High-Voltage Support
CANFD support distinguishes the Manta M8P from the Octopus V1.1's standard CAN bus. CANFD runs at up to 5Mbit/s in the data phase versus CAN's 1Mbit/s maximum. This bandwidth matters when streaming accelerometer data from an ADXL345 mounted on the toolhead — input shaper calibration generates bursts of data that can saturate a 1Mbit/s link.
High-voltage driver support up to 60V opens the door to 48V stepper systems. Running TMC5160 drivers at 48V instead of 24V doubles the voltage headroom, allowing higher stepper speeds before back-EMF causes missed steps. This is relevant for high-speed printing above 300mm/s where standard 24V systems hit their limits on heavy toolheads.

Who Should Buy This
The integrated SBC socket means one fewer board, one fewer USB cable, and cleaner wiring inside the electronics bay. The STM32H723 handles input shaping calculations with headroom to spare.
CANFD at 5Mbit/s handles accelerometer data from toolhead boards like the EBB36 without bottlenecking during input shaper calibration. Standard CAN at 1Mbit/s can drop packets during ADXL345 streaming.
The Manta M8P at $99 plus a CB1 at $35 totals $134. An Octopus V1.1 at $65 plus a BTT Pi at $30 totals $95. The Manta is better hardware but costs $39 more for the integrated approach.

The Ender 3 needs 4 drivers and a simple host. The SKR Mini E3 V3 at $45 is a drop-in replacement. The Manta's 8 drivers and SBC socket are wasted on a bed-slinger with 4 steppers.

If configuring firmware and wiring stepper drivers feels like a lot, the Bambu Lab A1 Mini prints out of the box for under $200.

Frequently Asked Questions
What SBC modules work with the BTT Manta M8P V2?
The Manta M8P V2 accepts any CM4-compatible module: Raspberry Pi CM4 (any RAM/eMMC variant), BTT CB1 ($35, Allwinner H616), and BTT CB2 ($45, Rockchip RK3566). The CB1 is the most popular budget choice for Klipper.
Is the Manta M8P V2 compatible with Klipper?
Yes. BTT provides pre-built Klipper firmware for the STM32H723 MCU, and the Voron community maintains reference configs. Flash via SD card or DFU. The SBC module runs MainsailOS or FluiddOS for the Klipper web interface.
What is CANFD and why does it matter for 3D printing?
CANFD (CAN with Flexible Data rate) runs at up to 5Mbit/s versus standard CAN's 1Mbit/s. This extra bandwidth prevents data loss when streaming accelerometer data from toolhead boards during input shaper calibration. For normal printing, standard CAN is sufficient.
Should I get the Manta M8P or the Octopus V1.1?
Get the Manta M8P if you want integrated SBC, CANFD, and the fastest MCU. Get the Octopus V1.1 if you already own a Raspberry Pi, want proven community documentation, or are on a tighter budget. Both have 8 driver slots.
Can I use 48V stepper motors with the Manta M8P?
Yes. The high-voltage driver inputs support up to 60V, making it compatible with 48V stepper systems using TMC5160 drivers. This enables higher print speeds by preventing back-EMF-induced missed steps at velocities above 300mm/s.
Does the Manta M8P V2 work without an SBC module?
The MCU runs standalone for motor control, but Klipper requires a Linux host. You can either plug a CB1/CB2/CM4 into the onboard socket or connect an external Raspberry Pi via USB. The onboard socket is the cleaner option.
What stepper drivers does the Manta M8P V2 support?
Any Pololu-form-factor STEP/DIR driver: TMC2209, TMC2226, TMC5160, DRV8825, and more. All 8 slots support UART and SPI configuration. TMC5160 drivers are recommended for 48V high-voltage setups.
