3.0 H7 Mainboard Control Board — STM32H723VGT6 550Mhz MCU, 24V/48V Optional Power, DotStar & USB A 5V

The 3.0 H7 mainboard is the H7 upgrade to the original F446-based 3.0 replacement microcontroller, designed to boost printing speed and handle higher voltages. Drivers have been revised to accept 24V/48V optional power supplies for demanding high-voltage, fast-speed operation. Key hardware updates from the F446 version include the STM32H723VGT6 MCU running at 550Mhz, a separate motor power input, and 60V most (one MOSFET output removed). Each motor driver offers selectable voltages and is equipped with a 120uF/63V capacitor to stabilize motor power. Additional features include DotStar color LED support and a USB A 5V power output, giving you both improved performance and extra connectivity for your 3D printer.
