1. There are provisions for Cartesian robots and extruders
2. Expansion to accessories such as controls
3. MOSFET for heater/fan output and 3 thermistor circuits
4. Incorporates 5A for additional safety and component protection
5. Additional 11A fuse for heated bed control
6. Fits 5 Pololu stepper driver boards
7. Pololu board pin header sockets, easy to replace or remove for future designs
8. I2C and SPI pins are left for future expansion
9. The MOSFET is hooked up into a PWM pin for generality
10. Servo connectors are used to connect to end stops, motors and LEDs. These connectors are gold plated, rated for 3A and are very compact
