🐙【Optional Main Control Chip】Uses 32-bit ARM Cortex-M4 series STM32F446ZET6 or STM32F407ZE main control chip. The two chips support Marlin and Klipper with high frequency.
🐙【Strong DIY Support】This motherboard supports up to 8 stepper drivers with 9 stepper driver outputs in total; And up to 6 PWM fans and 2 always-on fans with the ability to individually select the voltage rail that will drive each fan. Select from Vin, 12V or 5V.
🐙【Motherboard Expansion Function】Support BLTouch, locked-rotor detection, shut down after printing, resume printing after power failure, CAN bus, U disk function, IIC expansion; at the same time reserved WIFI interface, PT100 thermistor interface (optional), dual Z-axis printer.
🐙【TMC2209 Driver Features】The TMC2209 stepper driver is not easy to lose steps and is in an ultra-quiet mode; the module has a large area of heat dissipation pad, which can reduce the temperature of the driver when it is working; the module supports three modes: STEP / DIR and UART.
🐙【TMC2209 Driver Mode】TMC Motor drivers can be used in SPI or UART mode by simply adjusting the onboard jumpers beneath each motor driver. Additionally, you can connect or disconnect the TMC DIAG pin using an onboard jumper allowing you to use hard end-stops or sensorless homing without the need to cut any pins.

BIGTREETECH Octopus V1.1 Control Board for Voron 2.4
Very fast delivery......
This is a great control board that I'm using for my Voron Trident. With fan connections up the wazoo, you'll likely never going to have any sort of issue with IO pins for various trinkets to add to your printer. All jumpers are "defaulted" to 24V which is perfect if you're building a Voron. All JST connectors are snug and secure, so no more accidental unplugging of a stepper here or there.
I don't quite understand what others are stating in their reviews as I found the documentation for the V1.0 board pretty much interchangeable with the V1.1 - and it's super easy to find on the BTT GitHub page.
Paired with a CAN toolhead board, I now have 4 stepper ports and drivers to spare, setting myself up quite nicely for a few experiments / mods for my new printer.
If I were pressed for a negative point on this board, the only thing I can possibly complain about is the CAN connector. I don't understand why it's an RJ45 connector as these don't really feature in any 3D printer I've seen. I can't imagine a 3D printing hobbyist would have this crimper in their toolbox, but perhaps that's just me. (With six various crimpers already in my toolbox...)
Can recommend this.
It`s a really goog quality product I love it and I m really happy with it.
But one information in the prospekt that explains the board is missing:
Which light on the controller board has what for an funktion.
