+## DESCRIPTION
+
+<mark>M5GO Base</mark>is a base of [M5GO IOT Starter Kit](en/product_documents/m5stack-core/m5go_iot_starter_kit) or [M5Fire](en/product_documents/m5stack-core/m5core_fire).
+
+M5GO Base is composed of battery(600mAh), M-Bus interface, charging indicator(red led), two RGB Bar, PORT B and PORT C.
+
+The charging indicator light will blink when base is charging, but the light will keep on when charge completed.
