Brushed Motor The Microchip 12F675 offers a number of interesting facilities that are used in this design. These facilities permit a much better ESC to be designed than is possible with a 12C5xx PIC, without the complexity of designs using larger PICs. Most standard ESCs convert the throttle setting into PWM rates using a simple linear mapping. So that 50% throttle corresponds to a 50% PWM. However, a 50% PWM rate is actually delivering only 25% of the full power to the motor. This is the standard configuration of this ESC also.
