+# 18V 5A H-Bridge breakout board
-* For driving DC motors, coils and other inductive loads
+* For driving **DC motors**, **coils** or other inductive loads
-* Bi-directional output
+* **Bi-directional** output control
-* Up to 18V, 5A
+* Input **3.0-18V**
-* Works with 1.8 - 5.0V logic
+* Output **up to 5A continuous**, up to 9A pulse
+* Works with **1.8V to 6.0V logic** level inputs
 * Overcurrent protection
 * Short circuit protection
 * Overheat protection
 * Integrated flyback diodes
 * Pretty idiot-proof
+* Uses CP2119L or TMI8260SP integrated circuit
 
 
 # Basic operation

-* Logic HIGH on the FORWARD pin makes the motor spin FORWARD (M+ becomes VIN, M- becomes GND)
+* Logic HIGH on the FORWARD pin makes the motor spin **FORWARD** (M+ becomes VIN, M- becomes GND)
-* Logic HIGH on the REVERSE pin makes the motor spin REVERSE (M+ becomes GND, M- becomes VIN)
+* Logic HIGH on the REVERSE pin makes the motor spin **REVERSE** (M+ becomes GND, M- becomes VIN)
-* Logic HIGH on BOTH pins makes the motor ACTIVELY BREAK (M+ becomes GND, M- becomes GND)
+* Logic HIGH on BOTH pins makes the motor ACTIVELY **BREAK** (M+ becomes GND, M- becomes GND)
-* Logic LOW on BOTH pins makes the motor FREESPIN (M+ floats, M- floats)
+* Logic LOW on BOTH pins makes the motor **FREESPIN** (M+ floats, M- floats)
 
 ## "Analog" control
 * The power of the motor can be precisely adjusted (0-100%) by applying a PWM SQUARE WAVE to the FORWARD/REVERSE pins
