+===== STATUS LED =====
+The MPINO-8A4T-S STATUS LED is an indicator mounted on the board. You can use it to show the operating state of your program.
+The STATUS LED is connected to digital pin D20. In a sketch, use ''LED_BUILTIN'' in place of D20. Set ''pinMode(LED_BUILTIN, OUTPUT)'' before controlling it. ''digitalWrite(LED_BUILTIN, HIGH)'' turns the LED on; ''digitalWrite(LED_BUILTIN, LOW)'' turns it off.
+**Note:** The STATUS LED is on the board and is separate from the external output terminals.
