Controller schematics and PCB designs

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.

The pwr_io/ subdirectory has the design for the isolated power and I/O board. It has a couple of modular DC-DC converters that provide an isolated supply to the MCU and display, and a separate isolated supply for the spindle encoder and servo control lines.

The ui/ subdirectory has the design for the carrier board for the rotary encoders used on the front panel (you'll need two of these). These connect via cables terminated in IDC connectors on the MCU board.
