+
+## Description
+
+**<mark>LEGO+</mark>** is a LEGO DC Motor Driver module. It's built in MEGA328 chip for driving and manage each motor port. The module also owns DC Power port, so that when the load current is too large after driving many motors, you can power those system through external power supply.
+
+LEGO+ module communicates with M5Core through IIC. The IIC address is 0x56.
+
+## Feature
+
+- Input voltage range of DC Power: 6-12V
+
+## Include
+
+-  1x LEGO+ module
+-  1x 10cm LEGO cable
+-  1x DC connector
