The EPC7C021 demo board is a three-phase motor demonstration board measuring 6.50” x 5.22” that utilizes the EPC7011L7C as the powertrain. The EPC7C021 is designed to be either stand-alone, the phases driven by external PWM signals, or to interface with the EPC9147A microcontroller interface board. The EPC7C006 board, measures 6.50 x 5.22 inches.
