This page covers any general information for the Fly-MMU V1.0 H723 board.
It is currently available through AliExpress.
The Fly-MMU V1.0 is compatible with both Duet 3 boards and STM32H723, STM32H743 and STM32F4 boards with spican modules running 3.5.1 and above.
CAN Termination
If using a single toolboard/expansion board, make sure the CAN jumper is installed, as indicated on the pinout.
If using multiple toolboards/expansion boards, only the last toolboard should have a CAN jumper installed.
Driver Power Source Selection
The drivers can be set to either take power from the main CAN-FD cable or from the HV input. A jumper should be added next to each driver to select the correct power source.
Maximum HV Input voltage
The driver sockets have been tested with 48v.
Initial Installation
The board that you will receive doesn’t have any bootloader or firmware installed so when plugged into a computer, the board will show as an unidentified device. Follow the bootloader installation instructions.
