PiBotHat

@@ -7 +7 @@
 This PiBot hat allows any Raspberry Pi or compatible to serve as a robot controller.  The footprint is identical to the Pi Zero and mounting holes are included to allow mounting to a Pi Zero with standoffs.  The hat includes:
 
-    A switch-mode power supply that will accept +6v to +24v battery input and generate the +5v required by the Pi.  Overcurrent protection is provided (but it is not protected against reverse polarity...maybe next spin...please be careful and observe the polarity markings on the battery connector!)
-    Active level shifters adapt the +3v3 input/output levels required by the Pi to the +5v input/output levels required by many sensor and controller modules.
-    A multi-channel PWM generator that will allow the Pi to control up to 5 motors (DC motor controllers or servo motors)

 Like the roboRIO, connectors are provided that allow many devices to be connected with a single cable that provides both power and signal connections.  Two level-shifter ICs and two transistors shift voltages between the 3v3 used by the Pi and the 5v required by most of the modules.
 Connectors are provided for:
 
-    2x DC motor controller (nominally the L298N dual motor controller but can use any)
-    9 degrees of freedom (9DOF) sensor: accelerometer, gyroscope, magnetometer
-    Ultrasonic rangefinder
-    3x servo motors
-    2x wheel encoders (or can be used for general-purpose I/O)
-    2x digital I/O
