Breakout board for Arduino Mega and Giga

The project consists of the design of number 2 PCBs. The first PCB named A is a breakout board for Arduino Mega and Giga, with a maximum size of 140x120 mm. The second PCB named B is a small board and it connects to PCB A with a flat cable, the size is not defined. In the PCBs there are JST HX - 2.54 or standard pin connectors, mosfets for power outputs, two A4988 modules to control 2 stepper motors and two DRV8833 modules to control 4 DC motors, there is also a 1W LED controlled by one of mosfets. The motor modules and mosfets must be equipped with jumpers to select the 5 or 12 volt power supply. Not all mosfets need to be controlled by pwm pins. All digital inputs must include a 10k ohm resistor, but with the possibility of excluding it. There are also digital and analog inputs, some modules and pins for I2C. I attach some images, they are only indicative of the position of the various connectors. In the first image, the Arduino board connects over to PCB A and it is upside down. In the second image, PCB A is inserted into the Arduino, it remains behind the PCB and perhaps manages to use a little more space. The third image is the legend of the various connectors. I also attached the list of all the connections and modules that need to be draw. I wrote some numbers of the Arduino pins that must be used such as the intterupt pins. PCBs must be 100% compatible with both Arduino Mega and Arduino Giga More information: [login to view URL] Arduino Mega [login to view URL] Arduino Giga [login to view URL]
