There are so many in the under $20 range and even under $5. Any STM32 based development board can connect to a Linux PC using USB, SPI I2C or whatever then the board will have a dozen or two or more pins. It will also have some useful hardware for making pulses and such. Don't make a board "adopt" one. Here is a compromise 1/2 way approach I made for controlling a LIDAR from a Linux PC. The design "adopts" a $3 STM board (it is blue in the drawing) and there is a green PCB I made to conectorize it so the wiring is neat. Making these green boards is easy. For a CNC you would put connectors on for the motors, encoders, limit switchesand power supply and do all the interconnect on the PCB avoiding the typical rat's nest. The PCB cost more to ship then to manufacture. So at most made one of these green boards with just small passive parts and connectors on it. It takes just hours and it low risk then you "plug-in" a STM32 based development board that acts as the brain. https://github.com/chrisalbertson/NeatoLidarInterfacePCB -- Chris Albertson Redondo Beach, California _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
