【Support 60V Input】Supports up to 8 3D printer motherboards with a maximum 60V stepper motor. The motor drive power supply supports up to 60V input (only for the motor drive power supply).

【6 Controllable Fans】Up to 6 controllable fans, two normally open fans, and both support power supply voltage, 12V, 5V options.

【Update Firmware: Klipper/Marlin/RRF】Supports firmware update via DFU mode. This is where the firmware is sent to the board directly from the PC and does not require a bootloader however this method is not recommended for novice users as discussed later in this document.

【Level conversion IC】Supports proximity sensor, jumper optional pull-up resistor, supports more models, supports BL Touch.

Really nice board when used with Klipper

Running 256 microsteps on a V-core 3.1 at 1000mm/s and 10k acceleration runs flawlessly and as quiet as this machine will ever get.

The option to run high voltage steppers is very nice, and the fact you can easily run "normal" and HV steppers at the same time is exceptionally well thought out.

I haven't found any flaws as everything I'm using works completely without issue.
