Design a PCB and Firmware for two BLDC wheels (1 month)

I need you to design a main PCB board to operate two-wheel BLDC hub motors and a few auxiliary components e.g. lights. You will also design a small joystick logic to talk with the main PCB board. So we want to use as many pre-built electronic modules as possible to simplify the design task. All the pre-built modules have already been selected. Specific model numbers will be provided in private chat. We also have done preliminary design validation with STM32F407 dev board. What you need to do is design a custom STM32F407 PCB board that links all the modules together, and write firmware to control the modules (with Keil uVision or Arduino language). Simple. The two wheels need to move forward, backward, accelerate, decelerate, turn, and stop. NO self balancing required. There will be auxiliary modules (already pre-built), including BLDC motor shield, IR proximity sensor (just sensor, no logic), LED headlights and tail lights ON/OFF, battery indicator LED's, GPS module (just module, no logic), bluetooth speaker module, beepers, bluetooth lock, solenoid spring actuator (ON/OFF), OFF switch. The following has bluetooth 4.0 connectivity: battery indication, speed adjustment, ON/OFF lock, LED lights, bluetooth speaker. The size of the main controller board + modules must not be bigger than W 70mm L 80mm H 50mm. The mini bluetooth joystick assembly must be small enough to fit inside palm of one's hand. The joystick shall be manipulated by the thumb. Must be waterproof. You will provide: - The code - The gerber files We will prototype your design on our end. Upon validation of the design's functionality, you will be paid. Time is of essence, we would like this project completed in 1 month's time.
