 ====== MPINO-8A8R ======
-MPINO-8A8R is a all-in-one industrial Arduino with 8 digital inputs and 8 relay outputs. A single PCB integrates 4 analog inputs, 6 PWM outputs, 2 isolated high-speed counter inputs, 4 interrupt inputs, and RS-232·RS-485·UART·I²C communication.

+===== STATUS LED =====
+The MPINO-8A8R 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 D13. In a sketch, use ''LED_BUILTIN'' in place of D13. 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.
+==== Example · Blink the STATUS LED ====
+This example turns the STATUS LED on and off at 0.5-second intervals.
+<code cpp>
+void setup() {
+  pinMode(LED_BUILTIN, OUTPUT);
+}
+void loop() {
+  digitalWrite(LED_BUILTIN, HIGH);  // LED on
+  delay(500);
+  digitalWrite(LED_BUILTIN, LOW);   // LED off
+  delay(500);
+}
