================ ST Nucleo F302R8 ================ The Nucleo F302R8 is a member of the Nucleo-64 board family. Configurations ============== ihm07m1_f32 and ihm07m1_b16: ---------------------------- These examples are dedicated for the X-NUCLEO-IHM07M1 expansion board based on L6230 DMOS driver for three-phase brushless DC motors. X-NUCLEO-IHM07M1 must be configured to work with FOC and 3-shunt resistors. See ST documentation for details.
