Motor control circuit based on PIC16F1503T

My open source PCB motor is my attempt to build a tiny brushless motor that is smaller, cheaper, and easier to assemble.
The unique feature of this motor design is that the stator is printed on a 4-layer PCB. The six stator poles are spiral traces wound into a star-shaped structure. Although these coils produce less torque compared to an iron-core stator, the motor is still suitable for high-speed applications.
It also features a 3D printed 4-pole rotor with a diameter of 16 mm and a thickness of 1.7 mm. So the total thickness of this axial flux motor adds up to 5 mm (not including the shaft) and the weight is 1.5 grams.
The idea was inspired by attempts to make smaller and cheaper drones. Mounting the motors to the PCB itself will lower the overall price of any microrobot, making swarm robots more affordable. Details My PCB motor is made from a 6 pole stator and a 4 pole 3d printed rotor printed on a 4 layer PCB. It has an outer diameter of 16 mm and a power rating of 1 watt. 
I came up with this idea when I was trying to design a small compact drone. PCB motors are much cheaper and easier to assemble than other micro brushless motors. My goal is to make the rotor part of the BOM and mount like any other component on the PCB.
