I buy them for about $3 each ebay.com/itm/1PC-STM32F103C8T6-ARM-STM32 <https://www.ebay.com/itm/1PC-STM32F103C8T6-ARM-STM32-Minimum-System-Development-Board-Module-For-Arduino/112716388143?epid=23002532325&hash=item1a3e6b972f:g:cs0AAOSwVlVaQ2o0> You can do this with no Meas card by going with USB, i2c or SPI directly back to the Raspberry Pi. You can buy something like this for $28 too. They typically have bigger versions of STM32 on them but for controlling two servo motors with a PID loop the cheaper part is enough. > > -- Chris Albertson Redondo Beach, California _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
