Description
This controller used for tune field-oriented control algorythms on BLDC/PMSM motors ******Voltage: 15-48V****** ******Current: 40A****** STM32F334 MCU 2 phase current sensing, dc-bus voltage sensing EN/DIR inputs, PWM-input, UART, CAN interface Encoder/HALL sensors interface !Inernal opAmp in STM32 used like follower for current sense opAmps offset voltage, it must be configured in firmware !Dont support sensorless 6-step mode - this revision havn't phase voltage sensing
