3.0 H7 Mainboard Control Board — STM32H723VGT6 550Mhz MCU, Fast 24V/48V Support

This 3.0 H7 mainboard is an H7-series replacement built from the original 3.0 F446 microcontroller design, upgraded for higher speed and voltage handling. The MCU has been upgraded to STM32H723VGT6 running at 550Mhz and the board includes a separate motor power input for improved performance. It also supports up to 60V most (one MOSFET output removed). All motor drivers have been revised to accept optional 24V or 48V power supplies to meet higher-voltage and fast-speed demands. Each driver offers selectable voltages and is fitted with 120uF/63V capacitors dedicated to the motor driver circuitry. Extras include DotStar color LED support and a USB A 5V power output for peripherals. Overall, this mainboard boosts printer capability while adding configurable power options and visual customization.
