First board design

For the first board design I opted for a basic design, like a breakout board. Once the prototype works correctly. But in the future the best option is to integrate a microcontroller to get the measurement and control the motor speed, obtaining this data via I2C, SPI, ...

Main board breakout

It's just a board with a MOSFET to control the motor speed and a pin header for the signals. To carry the rotor signals (VCC,GND,SDA,SCL,XSHUNT+ENCODER) I'm going to use the pins from a SD card slot.
