From the project
Electronic Leadscrew for Optimum TU-2506V-ELS lathe
This directory contains the schematics and PCB CAD files for the controller boards. To fit in the available space in the lathe casting they are designed as a stack.
The mcu/ subdirectory contains the designs for the MCU carrier board, which basically exists to route signals from the STM32F411 Black Pill board to the adjacent ones via headers. The character VFD display also connects to this board via extended headers.
